PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. READ AND UNDERSTAND BOTH THE SPECIFIC INFORMATION GIVEN IN THE OPERATING MANUAL FOR THE WELDER AND/OR OTHER EQUIPMENT TO BE USED AS WELL AS THE FOLLOWING GENERAL INFORMATION.
ARC WELDING SAFETY PRECAUTIONS
1. a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
b. In semi-automatic and automatic wire welding, the
electrode, electrode reel, welding head and nozzle or semi-automatic welding gun are also electrically “hot”.
c. Insulate yourself from work and ground using dry
insulation. When welding in damp locations, on metal framework such as floors, gratings or scaffolds, and when in positions such as sitting or Lying, make certain the insulation is large enough to cover your full area of physical contact with work and ground.
d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection should be as close as possible to the area being welded.
e. Ground the work or metal to be welded to a good
electrical (earth) ground.
f. Maintain the electrode holder, work clamp, welding
cable and welding machine in good, safe operating condition. Replace damaged insulation.
g. Never dip the electrode holder in water for cooling. h. Never simultaneously touch electrically “hot” parts of
electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders.
i. When working above floor level, protect yourself from
a fall should you get a shock.
j. Also see items 4c and 6.
2. a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone. When welding on galvanised, lead or cadmium plated steel and other metals which produce toxic fumes, even greater care must be taken.
b. Do not weld in locations near chlorinated hydrocarbon
vapours coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapours to form phosgene, a highly toxic gas, and other irritating products.
c. Shielding gases used for arc welding can displace air
and cause injury or death. Always use enough ventilation, especially in confined areas, to ensure breathing air is safe.
d. Read and understand the manufacturer’ s instructions
for this equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employer’s safety practices.
e. Also see Item 7b.
3. a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to AS
1674.2-1990 standards.
b. Use suitable clothing made from durable flame
resistant material to protect your skin and that of your helpers from the arc rays.
c. Protect other nearby personnel with suitable non
flammable screening and/or warn them not to watch the arc or expose themselves to the arc rays or to hot spatter or metal.
4. a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Have a fire extinguisher readily available.
b. Where compressed gases are to be used at the job
site, special precautions should be used to prevent hazardous situations. Refer to AS1674 Parts 1 & 2 “Safety in Welding and Allied Processes”, WTIA Technical Note 7 “Health and Safety in Welding” and the operating information for the equipment being used.
c. When not welding, make certain no part of the
electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard.
d. Do not heat, cut or weld tanks, drums or containers
until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapours from substances inside. These can cause an explosion even though the vessel has been “cleaned”. For information purchase AS 1674-1990.
e. Vent hollow castings or containers before heating,
cutting or welding. They may explode.
f. Sparks and spatter are thrown from the welding arc.
Wear oil free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a welding area.
g. Connect the work cable to the work as close to the
welding area as possible. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail.
h. Also see Item 7c.

IMA 578BLA Maxmig 210 Page 3
5. a. Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators, designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.
b. Always keep cylinders in an upright position and
securely chained to an undercarriage or fixed support.
c. Cylinders should be located :
Away from areas where they may be struck or
subjected to physical damage.
A safe distance from arc welding or cutting
operations and any other source of heat, sparks or flame.
d. Never allow the electrode, electrode holder, or any
other electrically “hot” parts to touch a cylinder.
e. Keep your head and face away from the cylinder valve
outlet when opening the cylinder valve.
f. Valve protection caps should always be in place and
hand-tight except when the cylinder is in use or connected for use.
g. Read and follow the instructions on compressed gas
cylinders and associated equipment, and AS 2030 Parts 1 & 2.
6. a. Turn off input power using the disconnect switch at the fuse box before working on the equipment.
b. Install equipment in accordance with the SAA Wiring
Rules, all local codes and the manufacturer’s recom­mendations.
c. Ground the equipment in accordance with the SAA
Wiring Rules and the manufacturer’s recommenda­tions.
7. a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.
b. Operate engines in open, well ventilated
areas or vent the engine exhaust fumes outdoors.
c. Do not add fuel near an open flame,
welding arc or when the engine is running. Stop the engine and allow it to cool before refuelling to prevent spilled fuel from vaporizing on contact with hot engine parts and igniting. Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated.
d. Keep all equipment, safety guards, covers
and devices in position and in good repair. Keep hands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repairing equipment.
e. In some cases it may be necessary to
remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts.
f. Do not put your hands near the engine fan.
Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running.
g. To prevent accidentally starting petrol
engines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate.
h. To avoid scalding do not remove the
radiator pressure cap when the engine is hot.

WELDING, EMF & PACEMAKERS
All welders should follow safe practices that minimise their exposure to electric and magnetic fields (EMF).
For welders wearing implanted pacemakers, safe welding practices are particularly important and additional procedures should be followed by those who have decided to continue to weld. (Hopefully in keeping with a doctor’s advice).
The following procedures will not eliminate exposure to EMF or the possibility of arc welding having an effect on a pacemaker, however if followed, they will significantly reduce exposure to electric and magnetic fields. Electric and magnetic fields are created any time electric current flows through a conductor, however it is not clear whether such exposure affects ones health.
Some researchers have reported that exposure to EMF may cause leukemia or other illnesses. These claims originally arose in relation to high voltage electric power lines and are very much in dispute in the medical and scientific arena, however the best advice is to minimise your exposure to EMF to protect your health should doctors eventually decide there is a risk.
There are four fundamental facts about EMF:
With direct current (DC), the field strength is relatively constant and does not change.
With alternating current (AC), the field strength constantly changes.
The greater the current flow, i.e. the higher the amps, the stronger the field created by the current
The closer the conductor or electrical device is to the body, the greater the exposure to the field.
Minimising exposure
All welders should use the following procedures to minimise EMF exposure.
Route electrode or gun and work cables together. Secure them with tape if possible.
Never coil the electrode lead around your body.
Do not place your body between the electrode and work cables. If your electrode cable is on your right side the work cable should also be on your right side.
Connect the work cable to the work piece as close as possible to the area being welded. (This is also a good practice to eliminate a common problem on welding - a poor work connection.
Do not work next to the welding power source.
Welders with Pacemakers
There is no question that the fields in arc welding can interfere with a pacemakers function. Generally the interference does not permanently damage the pacemaker. Once the wearer leaves the arc welding environment or stops welding, the pacemaker returns to normal functioning. The welding arc has little or no effect on the operation of some pacemakers, especially designs that are bi-polar or designed to filter out such interference.
For a welder or anyone working around electrical equipment the selection of a pacemaker is very important. Get a doctor’s advice about which pacemaker is the least sensitive to interference from welding while still being medically suitable.
In addition to the normal safety precautions, the following additional procedures should be adopted by welders with pacemakers.
Use gas welding when the application is suitable.
Use the lowest current setting appropriate for the application. Do not exceed 400 amps. Low current (75-200 amps) direct current (DC) welding should be used if arc welding is necessary. Do not TIG weld with high frequency.
Do not use repeated, short welds. Wait about ten seconds between stopping one weld and starting the next. When having difficulty starting an electrode, do not re-strike the rod repeatedly.
If you feel light headed, dizzy or faint, immediately stop welding. Lay the electrode holder down so that it does not contact the work and move away from any welding being performed. Arrange your work in advance so that, if you become dizzy and drop the electrode holder, the electrode holder will not fall on your body or strike the work.
Do not work on a ladder or other elevated position or in a cramped, confined place.
Do not work alone. Work only in the presence of an individual who understands these precautions and the possible effect welding may have on your pacemaker.
Do not work near spot welding equipment.
If you have a pacemaker and wish to continue arc welding, discuss this and any other questions you may have with your physician and follow his or her advice. The doctor may wish to contact the pacemaker manufacturer for a recommendation. As mentioned before, the design of the pacemaker significantly affects the degree to which it is subject to interference from a welding circuit. Do not rely on the fact that you know another welder with a pacemaker who has welded for years without experiencing a problem. That welder and his or her pacemaker may be quite different from you and your pacemaker.

Conformance
Products displaying the C-Tick mark are in conformity with Australian/New Zealand requirements for Electromagnetic Compatibility (EMC). They are:
manufactured in conformity with Australian/New Zealand Standard (Emission):- AS/NZS 3652 ‘Electromagnetic Compatibility - Arc Welding Equipment’ (Identical to and reproduced from British Standard EN 50199)
for using with other Lincoln Electric/LiquidArc equipment.
designed for industrial and professional use.
Introduction
All electrical equipment generates small amounts of electromag­netic emission. Electrical emission may be transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions are received by other equipment, electrical interference may result. Electrical emissions may effect many kinds of electrical equipment: other nearby welding equipment, radio and TV transmitters and receivers, numerical controlled machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions may be required when a welding power source is used in a domestic establishment.
Installation and Use
The purchaser/user is responsible for installing and using the welding equipment according to the manufacturer’s instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the purchaser/user of the welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases this remedial action may be as simple as earthing (grounding) the welding circuit (see note below). In other cases it could involve constructing an electro­magnetic screen enclosing the power source and the work complete with associated input filters. In all cases electromagnet­ic disturbances must be reduced to the point where they are no longer troublesome.
NOTE: The welding circuit may or may not be earthed for safety reasons according to national codes. Changing the earthing arrangements should only be authorised by a person who is competent to assess whether the changes increase the risk of injury, eg. by allowing parallel welding current return paths which may damage the earth circuits of other equipment.
Assessment of Area
Before installing welding equipment the purchaser/user shall make an assessment of potential problems in the surrounding area.
The following shall be taken into account: a. Other supply cables, control cables, signalling and telephone
cables above, below and adjacent to the welding equipment;
b. Radio and television transmitters and receivers; c. Computer and other control equipment; d. Safety critical safety equipment, eg. guarding of industrial
equipment;
e. The health of people around, eg. the use of pacemakers and
hearing aids;;
f. Equipment used for calibration or measurement;
g. The immunity of other equipment in the environment. The
purchaser/user shall ensure that other equipment being used in the environment is compatible. This may require additional protection measures;
h. The time of the day that welding or other activities are to be
carried out.
The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.
Methods of Reducing Emissions
Mains Supply
Welding equipment should be connected to the mains supply according to the manufacturer’s recommendations.If interference occurs, it may be necessary to take additional precautions such as filtering the mains supply. Consideration should be given to shielding the supply cable of permanently installed welding equipment in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The shielding should be connected to the welding power source so that good electrical contact is maintained between the conduit and the welding power source enclosure.
Maintenance of the Welding Equipment
The welding equipment should be routinely maintained according to the manufacturer’s recommendations. All access and service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding equipment should not be modified in any way except for those changes and adjustment covered in the manufacturer’s instructions. In particular, the spark gaps of arc initiation and stabilising devices should be adjusted and maintained according to the manufacturer’s recommendations.
Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, running at or close to the floor level.
Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered. However, metallic components bonded to the work piece will increase the risk that the operator could receive a shock by touching these metallic components and the electrode at the same time. The operator should be insulated from all such bonded metallic components.
Earthing of the workpiece
Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of its size and position, eg. ship’s hull or building steelwork, a connection bonding the workpiece to earth may reduce emissions in some, but not all instances. Care should be taken to prevent the earthing of work pieces increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection of the workpiece to earth should be made by direct connection to the workpiece, but in some countries where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected according to national regulations.
Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire welding installation may be considered for special applications.*

2. Remove the cylinder cap. Inspect the cylinder valve for damaged threads, dirt and dust. For cylinders having an external thread fitting, remove any dust and dirt from the threads with a clean cloth.
DO NOT ATTACH THE REGULATOR/FLOWMETER IF CYLINDER VALVE IS DAMAGED! Inform your gas supplier of this condition.
3. Stand to one side away from the outlet and open the cylinder valve for an instant. This blows away any dust or dirt which may have accumulated in the valve outlet.
4. Inspect the regulator/flowmeter for damaged threads and seals, dirt and dust. Remove dust and dirt with a clean cloth.
DO NOT USE THE REGULATOR/FLOWMETER IF DAMAGE IS PRESENT! Have an authorised repair station repair any damage.
5. Attach the regulator/flowmeter to the cylinder valve and tighten the union nut(s) securely with a spanner.
6. Attach the inlet gas hose to the outlet fitting of the regulator/flowmeter, and tighten the union nut securely with a spanner.
7. Before opening the cylinder valve, turn the regulator adjusting knob counter-clockwise until the adjusting spring pressure is released.
8. Open the cylinder valve slowly a fraction of a turn. When the cylinder pressure gauge pointer stops moving, open the valve fully.
9. The regulator/flowmeter is adjustable. Set it for the flow rate recommended for the procedure and process being used before starting to weld.
1.4 Gun and Cable
The Maxmig 150 3m Ergonomic MIG gun and cable provided with the machine has a factory fitted 0.6-1.0mm liner and a 0.9mm contact tip.
1. Lay the cable out straight.
2. Make sure all pins on the gun cable connector are aligned with the proper mating sockets on the front panel gun connector and then join the connectors and tighten the hand nut on the gun cable connector.
Note: If a gun and cable other than the supplied gun is to be used, it must conform to standard European-style connector specifications. See diagram under.
The gun trigger switch must be capable of switching 10 milliamps at 60 volts DC—resistive.
1.5 Output Polarity Connection
The integrated machines are shipped from the factory connected electrode (+)ve. This is the normal polarity for GMA welding. The gun polarity can be changed by placing the flexible lead protruding from the front of the machine to the required output stud, eg. for electrode (-)ve, connect the lead to the (-)ve output stud.
The remote wire feeder machines are connected to the power source via a control/electrode/gas cable assembly. The electrode cable is connected to the required output stud. The control cable connects to the plug in the front panel of the power source.
Connect the work lead to the other output stud.
Gas under pressure is explosive. Always keep gas cylinders in an upright position and always keep chained to undercarriage or stationary support. Refer “Safety in Welding and Cutting” - ANSI Standard Z49-1 and WTIA Technical Note 7 available from the Welding Technology Institute of Australia.
WARNING
Never stand directly in front of or behind the regulator/flowmeter when opening the cylinder valve. Always stand to one side.
WARNING
The gun trigger switch connected to the gun trigger control cable must be a normally open, momentary switch. The terminals of the switch must be insulated from the welding circuit. Improper operation of, or damage to, the machine might result if this switch is common to an electrical circuit other than the machine trigger circuit.
CAUTION
Turn the welder power switch off before installing gun and cable.
WARNING
Turn the welder power switch off before changing polarity.
WARNING
Be sure to keep your face away from the valve outlet when “cracking” the valve.

2. OPERATING INSTRUCTIONS
2.1 Duty Cycle
The machine is rated at the following duty cycles:
(1) Based on 10 min. time period (i.e., for 25% duty cycle, it is
2.5 minutes actual welding and 7.5 minutes with no welding output, but with the input power remaining on keeping the cooling fan operative.)
2.2 Control Panel
a) Power Switch
The mains power switch is incorporated in the “coarse” output voltage control rotary switch. In the “0” positions the input mains power is switched off.
b) Pilot Light
This light illuminates when the input mains power is switched on.
c) Volts Control
The output voltage is controlled by two rotary switches. One rotary switch provides two “coarse” voltage settings as well as switching the mains power on. The other rotary switch provides the user with a selection of eight “fine” voltage settings. The selection between these two switches allows the user to select any one of sixteen welding voltages.
The approximate weld voltages for the switch positions are:
d) Wire Feed Speed Control *
Use this control to adjust the speed at which the electrode wire feeds when welding. This is in effect a current control as the power source will deliver the current necessary to melt the wire. The higher the speed, the more current will be required. Wire feed speed range is approximately 1 to 20 meters/min (40 to 790 inches/min.).
Operation of the gun trigger switches the wire feed motor on and off, depending upon the mode setting. The wire feed motor is dynamically braked to minimise wire overrun after welding has ceased.
Welding voltage is available immediately the gun trigger is operated, but when welding is stopped there is a factory set delay of approximately 1/2 sec. after wire feed has stopped to allow the electrode to burn back slightly and prevent sticking in the crater.
e) Spot Welding *
In spot welding mode welding takes place for a pre-set time and then stops automatically. Welding time is adjustable between 0.5 sec. and 4 sec. by operation of the spot weld control on the front panel. There is a positive click in the extreme anti-clockwise position to indicate that the spot weld feature is “off”.
* Mounted on machine control panel for Integrated units.
Mounted on remote wire feeder for Remote units.

IMPORTANT SAFETY NOTE: In 2T mode {refer 2.2 (h)}, this DC Constant Voltage wire welder provides “COLD” electrode when the gun trigger is not operated. Conversely, the output terminals are “LIVE” when the gun trigger is “activated” when pressed in 2T mode, or triggered on in 4T mode.
IMA 578BLA Maxmig 210 Page 9
f) Gas Purge *
Use the gas purge push button to operate the gas solenoid to purge air from the hose after connecting a new gas cylinder. Gas purge will only operate while the button is held in.
g) Wire Inch *
Use this push button to operate the wire feed motor and “cold” inch the wire.
h) 2T/4T Operation *
A two position switch on the front panel provides two modes of operation of the gun trigger. In 2T mode, the gun trigger is pressed to start welding and released to stop.
In 4T mode, pressing the gun trigger only operates the gas solenoid, allowing shielding gas to flow. Releasing the trigger activates the contactor which starts the wire feed motor and connects welding current to the wire so that welding may commence. To stop welding, the trigger must again be operated; pressing it stops the wire feed, activates the burn back time delay and opens the contactor after the pre-set burn back time. Releasing the trigger stops the gas flow.
To recommence welding, the above cycle must be repeated.
i) Over temperature light
Indicates that the thermostats have operated to protect unit from over temperature.
* Mounted on machine control panel for Integrated units.
Mounted on remote wire feeder for Remote units.
3. Setting Up for Welding
The following items are required:
1) A reel of wire of suitable size and type .
2) A suitable gun and cable assembly with a “Euro” connector and the correct tip and, if necessary gas nozzle for the consumable being used. (A Maxmig 150 MIG gun is supplied).
3) Correct drive rolls for the wire size and type to be used. The wire feeder is supplied with a 0.9/1.2mm hard wire feed roll as standard; drive rolls for other types and sizes are available as spare parts. (see table on page
10).
4) A work return cable and clamp.(supplied)
5) Normal welding accessories including helmet or hand shield with suitable lens, gloves etc.
6) If a gas shielded process is to be used, a cylinder of appropriate gas is required. (Regulator/flowmeter and hose are supplied.) If gas shielding is required, connect the gas hose.
Remember that gas cylinders may explode if damaged, so ensure that all gas cylinders are securely mounted.
Ensure that the correct type and size wire feed rolls are fitted. In replacing wire feed rolls, ensure that the key and keyway are correctly positioned and tighten the knurled locking screw securely.
Fit a spool of appropriate wire onto the 50mm spool hub so that, for the integrated model, as wire is fed the spool turns anti­clockwise when looking at the spool. For the remote unit, the unit spool must turn clockwise as the wire is fed. Carefully release the end of the wire from the spool ensuring that the released end is held to stop the wire from unravelling. Cut off the end kink to give a smooth straight end of wire.
Obtain a gap between the wire feed roll and the pressure roll by lifting the cam latch. Feed the wire end into the guide tube, between the drive rolls, and into the “Euro” connector guide until it protrudes about 20mm out of the front of the “Euro” connector. Close the drive rolls by lowering the cam latch ensuring the rolls firmly hold the wire. Adjust the tension so that wire feeds smoothly.
Do not overtighten.
Fit the gun and cable assembly onto the “Euro” connector by slipping the end of wire into the cable wire hole. Tighten the “Euro” connector lock ring.
Activate the power source, set the wire feed speed to 4 on the dial and press the wire inch push button. The wire feed roll should turn, feeding the wire further up the gun and cable assembly.
Ensure there are no kinks or sharp bends in the gun cable and hold the wire inch button until the wire emerges from the gun. It is good practice to remove the tip when first feeding a new coil of wire, then refitting over the wire and tightening.
Cut off the end of the wire leaving 10mm to 15mm stick-out. Select required polarity. See Section 1.5 - Output Polarity
Connection.
4. Welding
Put into 2T mode. Select the output voltage required to suit the job by setting the
coarse and fine rotary switches. Before beginning welding, ensure the wire protrudes from the
gun tip by approximately 10-15mm. Ensure welding shield and other protective clothing are in place. Present the protruding electrode just off the work. Maintain a steady grip on the gun, protect your eyes with a welding shield, then press and hold the gun trigger to create the arc.
If it is necessary to adjust the weld voltage, stop welding before changing either or both of the rotary switches.
Adjust the wire feed speed as necessary to suit the job. At the completion of the weld, release the gun trigger and pull the gun away from the work to stop the arc.
4T mode should only be used for long welds by experienced operators.
Integrated machine
When the gun trigger is pressed (2T mode) or pressed and released the first time (4T mode), the wire is at welding voltage. The wire should never touch the case of the wire feeder. If it does, it is possible for the wire to arc to the case.
Any wire overrun should be avoided.
WARNING
Page 10 Maxmig 210 IMA 578BLA
Changing Electrode Size and Type
When changing the electrode size or type, ensure the wire feed roll is the correct size and type for the electrode. Wire feed rolls have two grooves each of different sizes. Ensure the roll is located by the key and keyway and firmly secured by knurled screw.
When changing to aluminium welding a new drive roll, cable liner and contact tip should be used.
Also check electrode polarity, as different processes may require different polarities.
Adjust Spool Tension
The spool should stop rotating when the wire feed roll stops. Overrun of the spool can cause the coil of wire to unravel. The spool hub should be tensioned so that it neither drags nor overruns. The tension can be set by adjusting the large nut inside the hub with a tube spanner.
*
The Maxmig 150 gun, with a 1.2mm tip and liner will be required for 1.2mm wires.
5. MAINTENANCE
Safety Precautions
Routine Maintenance
General
In extremely dusty locations, dirt may clog the air passages and cause the welder to run hot. Blow dirt out of the welder with low­pressure air at regular intervals to eliminate excessive dirt and dust build-up on internal parts.
The fan motors have sealed ball bearings which require no service.
Welding Thermal Overload Protection
The Maxmig 210 has built-in protective thermostats that respond to excessive temperature. They open the wire feed and welder output circuits if the machine exceeds the maximum safe operating temperature because of a frequent overload, or high ambient temperature plus overload. The over temperature light on the control panel glows if thermostats open. The thermostats automatically reset when the temperature reaches a safe operating level.
Gun and Cable Maintenance
Cable Cleaning
Clean cable liner after using approximately 150kg of electrode. Remove the cable from the wire feeder and lay it out straight on the floor. Remove the contact tip from the gun. Using an air hose and approx. 350 kPa (50psi) pressure, gently blow out the cable liner from the gas diffuser end.
Flex the cable over its entire length and again blow out the cable. Repeat this procedure until no further dirt comes out.
Gun Tips and Nozzles
The gun tip should be replaced when worn. Replace with the correct size for the wire type and diameter. Too large a tip for the electrode wire will cause arcing within the gun cable and possible jamming of the wire within the cable .
Remove spatter from inside of gas nozzle and from tip after each 10 minutes of arc time or as required.
Drive Rolls and Guide Tubes
After every coil of wire, inspect the wire drive mechanism. Clean it as necessary by blowing with low pressure compressed air. Do not use solvents for cleaning the idle roll because this may wash the lubricant out of the bearing. All drive rolls are stamped with the wire sizes they will feed. If a wire size other than that stamped on the roll is to be used, the drive roll must be changed.
Avoiding Wire Feeding Problems
Wire feeding problems can be avoided by observing the following gun handling procedures:-
1. Do not kink or pull gun cable around sharp corners.
2. Keep the gun cable as straight as possible when welding or loading electrode through cable.
3. Keep gun cable clean by following maintenance instructions.
4. Use only clean, rust-free electrode. LiquidArc electrode has proper surface lubrication.
5. Replace contact tip when the arc starts to become unstable or the contact tip end is fused or deformed.
Input Lead
If the supply cord is damaged, it must be replaced with a special cord, Part No. AS2373-2.
Excessive pressure at the start may cause dirt to form a plug.

GROUND TEST PROCEDURE
Warning: This procedure is only suitable for applications using DC mega testers up to 500V.
Note: This procedure is for ‘machines as built’ many
modifications could have taken place over the life of a particular machine, so details of this procedure may need to be ‘adjusted’ to suit these modifications.
For prompt service contact your local authorised LiquidArc Field Service Shop.
The insulation resistance values listed below are from Australian Standard AS1966.1
If any problems are encountered refer to your nearest authorised LiquidArc Field Service Shop.
1. Disconnect input cable from power supply.
2. Disconnect gun assembly and work cable.
3. Remove the RHS side panel from power source and LHS from traveller (if applicable).
4. Jumper the two (2) AC terminals and the (+)ve terminal of the bridge rectifier, (a total of three (3) places).
5. Disconnect the PCB plug and insert a 20 way shorting plug into the harness.
6. Switch the ‘fine’ control rotary switch to position ‘one’ (1) and switch the ‘course’ control toggle switch to position (1).
7. Primary Test: Connect one lead of the mega tester to the frame of the machine and the other lead to the Active terminal of the input plug. Apply the test. (Min. resistance 1MΩ)
8. Welding Circuit Test: Connect one lead of the mega tester to the frame of the machine and the other lead to the (+)ve output stud. Apply the test. (Min. resistance 1M)

11. Remove all jumpers and reconnect all leads and plugs.
12. Refit all panel work previously removed.
ELECTRIC SHOCK CAN KILL
Changing Settings for Wire Burnback and Motor Acceleration
If Electrode Wire Burnback or Motor Acceleration need to be altered from factory settings, because of the welding procedure being used, locate the PCB in the power source or in the traveller.
On the PCB there is a trimmer labelled ‘R.T.S.’, this trimmer controls the wire burnback time. It adjusts a time period from when the drive motor stops until the power source and gas solenoid are switched off. [Approximately 0.1 seconds (when fully counter-clockwise) to approximately 1.1 seconds (when fully clockwise)]. Factory setting is mid-position.
Another trimmer on the PCB is labelled ‘Rampa’, this trimmer controls the acceleration rate of the drive motor from stationary to the set wire feed speed. Maximum acceleration when fully counter-clockwise to minimum acceleration when fully clockwise. This is particularly important when welding aluminium wire. The factory setting is fully clockwise.
Procedure for Replacing PC Boards
Before replacing a PC board suspected of being defective, visually inspect the PC board in question for any visible damage to any of its components and conductors on the back of the board.
1. If there is no visible damage to the PC board, install a new one and see if this remedies the problem. If the problem is remedied, reinstall the original PC board to see if the problem still exists. If the problem no longer exists with the old PC board:
a. Check the PC board harness connector pins for
corrosion, contamination, or looseness.
b. Check leads in the plug harness for loose or
intermittent connection.
2. If PC board is visibly damaged, before possibly subjecting the new PC board to the same cause of failure, check for possible shorts, opens or grounds caused by:
a. Damaged lead insulation. b. Poor lead termination, such as a poor contact or a
short to adjacent connection or surface. c. Shorted or open motor leads, or other external leads. d. Foreign matter or interference behind the PC board.
3. If PC board is visibly damaged, inspect for cause, then remedy before installing a replacement PC board.

CUSTOMER ASSISTANCE POLICY
The business of The Lincoln Electric Company is manufacturing and selling high quality welding equipment, consumables, and cutting equipment. Our challenge is to meet the needs of our customers and to exceed their expectations. On occasion, purchasers may ask Lincoln Electric for advice or information about their use of our products. We respond to our customers based on the best information in our possession at that time. Lincoln Electric is not in a position to warrant or guarantee such advice and assumes no liability, with respect to such information or advice. We expressly disclaim any warranty of any kind, including any warranty of fitness for any customer’s particular purpose, with respect to such information or advice. As a matter of practical consideration, we also cannot assume any responsibility for updating or correcting any such information or advice once it has been given, nor does the provision of information or advice create, expand or alter any warranty with respect to the sale of our products.
Lincoln Electric is a responsive manufacturer, but the selection and use of specific products sold by Lincoln Electric is solely within the control of, and remains the sole responsibility of the customer. Many variables beyond the control of Lincoln Electric affect the results obtained in applying this type of fabrication methods and service requirements.

WARRANTY LIMITATIONS
Certain conditions warranties and obligations are implied by law (for example under the Trade Practices Act 1974) and cannot be excluded or modified ("the statutory warranties").
Where the statutory warranties do apply then any express warranties given by Lincoln (the "express warranties") are given in addition and without derogation from the statutory warranties. Apart from the express warranties and (in cases where they apply by law but not otherwise) the statutory warranties Lincoln gives no warranties whether express or implied by operation of law or otherwise in respect of any goods manufactured or supplied by Lincoln or by its authorised distributor.
Any warranty whether express or statutory and the term of any such warranty as set out herein commences on the date Lincoln or Lincoln’s authorised distributorship forwards the goods from the premises of Lincoln or Lincoln’s authorised distributor to the purchaser.
In respect of any claim under the warranty herein provided a purchaser must furnish Lincoln with written notice of any claim under the warranty within the time period of the warranty as further specified herein.

a) The cost of replacing the goods; b) The cost of obtaining equivalent goods; or c) The cost of having the goods repaired whichever remedy in its absolute
discretion Lincoln chooses.
Upon request by Lincoln the purchaser must permit Lincoln to inspect the goods the subject of any claim under this warranty and Lincoln may at its absolute discretion repair or replace the goods F.O.B. at its own premises or at such other premises as Lincoln may designate provided that all freight charges to and from Lincoln’s premises or such other premises as Lincoln may designate shall be paid by the purchaser.
Subject to the express and statutory warranties hereinbefore provided Lincoln provides no other warranties in respect of the manufacture or sale of goods and in particular Lincoln shall have no responsibility or liability in respect of:
