EMF Information

Welding or cutting current, as it flows through the welding or cutting cables, will cause electromagnetic fields. There has been and still is some concern about such fields. However, after examination the committee of the National Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to power-frequency electric and a magnetic field is a human health hazard.” However, studies are still going forth and evidence continues to be examined. Until the final conclusions of the research are reached, you may wish to minimize your exposure to electromagnetic fields when welding or cutting.

To reduce magnetic fields in the workplace, use the following procedures:

1. Keep cables close together by twisting or taping them.

2. Arrange cables to one side and away from the operator.

3. Do not coil or drape cables around your body.

4. Keep welding or cutting power source and cables as far away from operator as practical.

5. Connect work clamp to work piece as close to the cut or weld as possible.

ABOUT PACEMAKERS & HEARING AIDS:

Pacemaker & Hearing Aid wearers consult your doctor first. If cleared by your doctor, then following the above procedures is recommended.

Personal Protection

Welding processes of any kind can be dangerous not only to the operator but to any person situated near the equipment, if safety and operating rules are not strictly observed.

THE WELDING ARC PRODUCES VERY BRIGHT ULTRAVIOLET AND INFRARED

LIGHT. THESE ARC RAYS WILL DAMAGE YOUR EYES AND BURN YOUR SKIN IF YOU ARE NOT PROPERLY PROTECTED. To reduce the risk of injury from arc rays, read,

understand, and follow the safety instructions. In addition, make certain that anyone else that uses this welding equipment, or is a bystander in the welding area understands and follows these safety instructions as well. Helmets and filter should conform to ANSI Z87.1 stan dards.

• Do not look at an electric arc without proper protection. A welding arc is extremely bright and intense and, with inadequate or no eye protection, the retina can be burned, leav ing a permanent dark spot in the field of vision. A shield or helmet with a #10 shade filter lens (minimum) must be used.

• Do not strike a welding arc until all bystanders and you (the welder) have welding shields and/or helmets in place.

• Do not wear a cracked or broken helmet and replace any cracked or bro ken filter lenses immediately.

• Do not allow the uninsulated portion of the wire feed gun to touch the ground clamp or grounded work to prevent an arc flash from being created on contact.

• Provide bystanders with shields or hel mets fitted with an appropriate shade filter lens.

• Wear protective clothing. The intense light of the welding arc can burn the skin in much the same way as the sun, even through light-weight clothing. Wear dark clothing of heavy material. The shirt worn should be long sleeved and the collar kept buttoned to protect chest and neck.

• Protect against reflected arc rays. Arc rays can be reflected off shiny sur faces such as a glossy painted surface, aluminum, stainless steel, and glass. It is possible for your eyes to be injured by reflected arc rays even when wearing a protective helmet or shield. If welding with a reflective surface behind you, arc rays can bounce off the surface and off the fil ter lens. It can get inside your helmet or shield and into your eyes. If a reflective background exists in your welding area, either remove it or cover it with something non-flammable and non-reflective. Reflective arc rays can also cause skin burn in addition to eye injury.

• Flying sparks can injure. Wear proper safety equipment to protect eyes and face. Shape tungsten electrode on grinder wearing proper protection and in a safe location. Keep flammables away and prevent fire from flying sparks.

FUMES, GASSES, AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS, AND

DEATH! To reduce the risk, read, understand, and follow the safety instructions. In addition, make certain that anyone else that uses this welding equipment or is a bystander in the welding area, understands and follows these safety instructions as well.

• Read and understand manufacturers SDS and MSDS.

• Do not weld in an area until it is checked for adequate ventilation as described in ANSI

standard Z49.1. If ventilation is not adequate to exchange all fumes and gasses generated during the welding process with fresh air, do not weld unless you (the welder) and all bystanders are wearing air-supplied respirators.

• Do not heat metals coated with, or that contain, materials that produce toxic fumes (such as

galvanized steel), unless the coating is removed. Make certain the area is well ventilated, and the operator and all bystanders are wearing air-sup plied respirators.

WWW.FORNEYIND.COM

• Do not weld, cut or heat lead, zinc, cad mium, mercury, beryllium, antimony, cobalt, manganese, selenium, arsenic, copper, silver, barium, chromium, vanadium, nickel, or similar met als without seeking professional advice and inspection of the ventilation of the welding area. These metals produce extremely toxic fumes which can cause discomfort, illness and death.

• Do not weld or cut in areas that are near chlorinated solvents. Vapors from chlori nated hydrocarbons, such as trichloroeth ylene and perchloroethylene, can be decomposed by the heat of an electric arc or its ultraviolet radiation. These actions can cause phosgene, a high ly toxic gas, to form, along with other lung and eye-irritating gasses. Do not weld or cut where these solvent vapors can be drawn into the work area or where the ultraviolet radiation can pene trate to areas containing even very small amounts of these vapors.

• Do not weld in a confined area unless it is being ventilated or the operator (and anyone else in the area) is wearing an air-supplied respirator.

• Stop welding if you develop momentary eye, nose, or throat irritation as this indi cates inadequate ventilation. Stop work and take necessary steps to improve ventilation in the welding area. Do not resume welding if physical discomfort persists.

Fire Prevention

FIRE OR EXPLOSION CAN CAUSE DEATH, INJURY, AND PROPERTY DAMAGE!

To reduce these risks, read, understand and follow the safety instructions. In addition, make certain that anyone else that uses this welding equip ment, or is a bystander in the welding area, understands and follows these safety instruc tions as well. Remember: arc welding by nature produces sparks, hot spatter, molten metal drops, hot slag and hot metal parts that can start fires, burn skin and damage eyes.

• Do not wear gloves or other clothing that contains oil, grease, or other flammable

substances.

• Do not wear flammable hair preparations.

• Do not touch the hot weld bead or weld puddle until fully cooled.

• Do not weld in an area until it is checked and cleared of combustible and/or flam mable

materials. Be aware that sparks and slag can fly 35 feet and can pass through small cracks and openings. If work and combustibles cannot be sepa rated by a minimum of 35 feet, protect against ignition with suitable, snug-fitting, fire resistant, covers or shields.

• Do not weld on walls until checking for and removing combustibles touching the other side of

the walls.

• Do not weld, cut, or perform other such work on used barrels, drums, tanks, or other

containers that had a flammable or toxic substance. The tech niques for removing flammable sub stance and vapors, to make a used con tainer safe for welding or cutting, are quite complex and require special educa tion and training.

• Do not strike an arc on a compressed gas or air cylinder. Doing so will create a brittle

area that can result in a violent rupture immediately or at a later time as a result of rough handling.

• Do not weld or cut in an area where the air may contain flammable dust (such as grain

dust), gas, or liquid vapors (such as gasoline).

• Do not handle hot metal, such as the work piece or electrode stubs, with bare hands.

• Wear leather gloves, heavy long sleeve shirt, cuffless pants, high-topped shoes, helmet, and

cap. As necessary, use additional protective clothing such as leather jacket or sleeves, fire resistant leggings, or apron. Hot sparks or metal can lodge in rolled up sleeves, pant cuffs, or pockets. Sleeves and collars should be kept buttoned and pockets eliminated from the shirt front.

• Have fire extinguisher equipment handy for immediate use. A portable chemical fire

extinguisher, type ABC, is recom mended.

WWW.FORNEYIND.COM

• Wear ear plugs when welding overhead to prevent spatter or slag from falling into ear.

• Make sure welding area has a good, solid, safe floor, preferably concrete or masonry, not tiled, carpeted, or made of any other flammable material.

• Protect flammable walls, ceilings, and floors with heat resistant covers or shields.

• Check welding area to make sure it is free of sparks, glowing metal or slag, and flames before leaving the welding area.

• Wear garments free of oil or other flammable substances such as leather gloves, thick cotton shirts with no synthetic materials, cuffless trousers, closed toed shoes. Keep long hair pulled back.

• Remove any combustibles such as lighters and matches before doing any welding.

• Follow requirements in OSHA and NFPA for hot work and have an extinguisher nearby.

High Frequency Radiation

• High Frequency (H.F) can interfere with radio navigation, safety services, computers and

communication equipment.

• It is the user’s responsibility to have a qualified electrician promptly correct any interference

problem resulting from the installation. Electrician should regularly check and maintain installation.

• Stop using the equipment if notified by the FCC about interference.

• Keep H.F. source doors and panels tightly shut and keep spark gaps at correct setting.

Arc Welding

• Computers and computer driven equipment can be harmed with electromagnetic energy.

• Be sure all equipment is compatible with electromagnetic energy.

• Keep welding cables short to reduce interference.

• Follow manual to install and ground machine.

• If interference continues, shield the work area or move the welding machine.

Electric Shock

WARNING: ELECTRIC SHOCK CAN KILL! To reduce the risk of death or serious injury

from shock, read, understand, and follow the safety instructions. In addition, make certain that anyone else who uses this welding equipment, or who is a bystander in the welding area understands and follows these safety instructions as well.

IMPORTANT! TO REDUCE THE RISK OF DEATH, INJURY, OR PROPERTY DAMAGE, DO NOT ATTEMPT OPERA TION of this welding equipment until you have read

BE SURE TO LOCATE THE WELDER ACCORDING TO THE FOLLOWING GUIDELINES:

• In areas free from moisture and dust;

• In areas with ambient temperature between 30° to 90°F;

• In areas free from oil, steam and corrosive gases;

• In areas not subjected to abnormal vibration or shock;

• In areas not exposed to direct sunlight or rain;

• Place at a distance of 12” or more from walls or similar obstructions that could restrict natural air flow for cooling.

Power Source Connection

This welder is designed to operate on a properly grounded 230V, 60HZ, single-phase alternating current (AC) power source fused with a 50A time-delayed fuse or circuit breaker. It is recommended that a qualified electrician verify the actual voltage at the receptacle into which the welder will be plugged and confirm that the receptacle is properly fused and grounded. The use of the proper circuit size can eliminate nuisance circuit breaker tripping when welding.

Do not operate this welder if the actual power source is less than 105 VAC. Contact a qualified electrician if this problem exists. Improper performance and/or damage to the welder will result if operated on inadequate or excessive power.

Before you make any electrical connection, make sure that supply voltage and frequency available at site are those stated in the ratings label of your welder.

The main supply voltage should be within ±10% of the rated main supply voltage. Too low a voltage may cause poor welding performance. Too high a supply voltage will cause components to overheat and possibly fail. The welder outlet must be:

• Correctly installed, if necessary, by a qualified electrician;

• Correctly grounded (electrically) in accordance with local regulations;

• Connected to the correct size electric circuit.

NOTE:

• Periodically inspect supply cable for any cracks or exposed wires. If it is not in good condition, have it repaired by a Service Center.

• Do not violently pull the input power cable to disconnect it from supply outlet.

WWW.FORNEYIND.COM

• Do not lay material or tools on the power supply cable. The cable may be damaged and result in electrical shock.

• Keep the supply cable away from heat sources, oils, solvents or sharp edges.

• If you use an extension cord, keep it as straight as possible. For lengths up to 50 ft. use 12 AWG. For lengths up to 100 ft. use 10 AWG.

Ventilation

Since the inhalation of welding fumes can be harmful, ensure that the welding area is effectively ventilated.

Additional Warnings

FOR YOUR SAFETY, BEFORE CONNECTING THE POWER SOURCE TO THE LINE CLOSELY FOLLOW THESE INSTRUCTIONS:

• An adequate two-pole switch must be inserted before the main outlet. This switch must be equipped with time-delay fuses.

• The ground connection must be made with a two-pole plug compatible with the above mentioned socket.

• When working in a confined space, the welder must be kept outside the welding area and the ground cable should be fixed to the workpiece. Never work in a damp or wet confined space.

• Do not use damaged input or welding cables.

• The welding torch should never be pointed at the operator or other people.

• The welder must never be operated without its panels attached. This could cause serious injury to the operator and could damage the equipment.

Wire Loading

Your MIG welder is designed to accept either 8” or 12” wire spools of mild steel, stainless steel or aluminum according to the type of metal you wish to weld. Wire spools aren’t supplied with the unit

and must be purchased separately.

ENSURE GAS AND ELECTRICAL SUPPLIES ARE DISCONNECTED. Before proceeding,

remove the nozzle and the contact tip from the torch.

• Open the side panel. Loosen the nut (Fig.4) (A) of the spool holder (Position 1) (brake drum). Remove the spacer (E). In the case you are replacing the wire spool, extract it by pushing the snap tongue (D).

• Remove the plastic protection from the spool. Place spool on the spool holder. Mount the spacer again (only for 8” spools) and tighten the lock nut.

Your MIG welder can also accept 4” wire spools. To mount 4” spools:

• Remove the wire spool from the spool holder.

• Loosen the nut, remove the spring and the washer; remove the spool holder from the pivot.

• Insert on the pivot the 4” wire spool; Mount the washer, the spacer and the spring.

• Tighten the lock nut.

TIGHTEN NUT. EXCESSIVE PRESSURE STRAINS THE WIRE FEEDING MOTOR. TOO

LITTLE PRESSURE DOES NOT ALLOW THE WIRE SPOOL TO STOP IMMEDIATELY.

• Loosen and lower the plastic knob (Fig. 5) (A). Release the upper roll (B) of the feeder. Extract the wire from the torch liner.

• When the wire is disconnected, grasp it with pliers so that it cannot exit from the spool. If necessary, straighten it before inserting it in the wire input guide (C). Insert the wire on the lower roll (D) and in the torch liner (E).

WARNING: Keep the torch straight when feeding a new

wire through the liner. Make sure the wire is cut cleanly (no burrs or angles) and that at least 1/2” from the end is straight (no curves). Failure to follow these instructions could cause damage to the liner.

• Lower the upper roll (B) and place the knob (A). Tighten slightly. If tightened too much, the wire gets locked and could cause motor damage. If not tightened enough, the rolls will not feed the wire. NOTE: When changing the wire diameter being used, or replacing the wire feed roll, be sure that the correct groove for the wire diameter selected is inside, closest to the machine. The wire is

WWW.FORNEYIND.COM

driven by the inside groove. Feed rolls are marked on the side identifying the groove nearest that side. Close the side panel of the machine. Connect the power supply cable to the outlet. Turn on the

• switch. Press the torch switch. The wire fed by the wire feeding motor at variable speed must slide through the liner. When it exits from the torch neck, release the torch switch. Turn off the machine. Mount the contact tip and the nozzle.

NOTE: When checking the correct exit of

the wire from the torch do not bring your face near the torch. You may run the risk of being wounded by the outgoing wire. Do not bring your fingers close when working! The rolls, when moving, Replace them

to the feeding mechanism

Replacing the Wire Liner

BEFORE PERFORMING THIS PROCEDURE, BE SURE THE GAS SUPPLY LINE AND

INPUT POWER CABLE ARE DISCONNECTED.

• Disconnect the torch from the machine.

• Place it on a flat surface and carefully remove the brass nut (1).

• Pull the liner out of the hose.

• I

nstall the new liner and mount the brass nut (1)

again.

In case you are replacing a Teflon or graphite wire liner, follow these instructions:

• Install the new liner and insert the wire liner collet (3) and the O ring (4).

• Mount the brass nut (1).

• Cut the wire liner close to the brass nut. NOTE: the length of the new wire liner must be the same as the liner you have just pulled out

of the hose.

• Connect the torch to the machine and install the wire into the feeding system.

How to Choose the Wire Liner for Direct and Euro Connect Torches

There are basically two types of wire liners: Steel and Teflon. Steel wire liners can be coated or noncoated. Coated wire liners are used for air-cooled torches. Teflon wire liners are recommended for aluminum welding as they allow smooth feeding of the wire.

Arrangement For Welding With a Spool Gun

WARNING: Electric shock can kill! Always turn the POWER switch OFF and unplug the power

cord from the AC power source before installing wire.

Before installing any welding wire into the unit, the appropriate drive roll must be placed into position on the wire drive mechanism. Ensure the groove is the proper shape and size for the wire being used. Adjust the drive roll according to the following steps:

1. Open the wire drive cover on the spool gun.

tension arm. Pull the drive tension arm away from the drive roller.

3. If needed, loosen the tension adjusting screw on the drive tension arm. Pull the drive tension arm up to allow access to the drive roll within the wire drive system. Rotate the black drive roll cap counterclockwise and remove it to reveal the metallic drive roll. Pull the drive roll off its shaft. NOTE: The drive roll has two wire size (.030” and .035”) grooves built into it. Ensure the corresponding groove and wire size are used. Replace the drive roll onto its shaft and drive roll cap onto the drive roll.

4. Find the side of the drive roller that is stamped with the same wire diameter as that of the wire being installed. Push the drive roller onto the drive roller shaft, with the side stamped with the desired wire diameter facing you.

5. Reinstall the drive roller cap and lock in place by turning it clockwise.

6. Remove the nozzle and contact tip from the end of the gun assembly.

7. Open the wire spool casing, located at the rear of the spool gun, by turning the retaining knob counterclockwise.

8. Unwrap the spool of wire and find the end of the wire.

9. After checking to make sure that your welder is disconnected from the AC power source, free the leading end of the wire from the spool, but do not let go of it until told to do so, or the wire will unspool itself.

10. Using a wire cutter, cut off the bent portion at the end of the wire so that you are left with a straight section of wire.

11. Unroll about 6” of welding wire from the wire spool.

12. Insert the leading end of the wire into the inlet guide tube (located in the Wire Spool Casing). Then push it across the drive roller and into the gun assembly about 6”.

13. Line the wire up in the appropriate top groove of the drive roller, then push the drive tension arm against the drive roller.

14. Flip the quick release drive tensioner back into position on the drive tensioner arm.

15. Tighten (turn clockwise) the drive tension adjusting knob until the tension roller is applying enough force on the wire to prevent it from slipping out of the drive assembly.

16. Let go of the wire.

17. The welding wire should always come off the top of the spool into the drive mechanism. NOTE: The purpose of the drive brake is to cause the spool of wire to stop turning at nearly the same moment that wire feeding stops.

18. Set the Drive Brake tension. NOTE: It is necessary to release the Drive Tensioner Arm while you are setting the Drive Brake Tension. Make sure you return the Drive Tension Arm to its locked position after adjusting the Drive Brake Tension. a) With one hand, turn the wire spool counterclockwise. This will cause the wire to feed

through the gun assembly continue turning it while adjusting the tension on the spool. b) With your free hand, tighten (turn clockwise) the drive brake adjustment knob. c) Stop tightening when drag is felt on the wire spool that you are turning. Then stop hand-

turning the wire spool. NOTE: If too much tension is applied to the wire spool, the wire

will slip on the drive roller or will not be able to feed at all. If too little tension is applied,

the spool of wire will want to unspool itself. Readjust the drive brake tension as necessary

to correct for either problem.

19. Trim the wire which is sticking out the end of the spool gun to about 1/2” in length.

20. Select a contact tip stamped with the same diameter as the wire being used.

21. Slide the contact tip over the wire protruding from the end of the gun.Thread the contact tip into the end of the gun and hand-tighten securely.

22. Install the nozzle on the gun assembly. For best results, coat the inside of the nozzle with anti-stick spray or gel.

23. Cut off the excess wire that extends past the end of the nozzle.

24. Replace the wire spool casing cover and tighten adjustment knob by turning it clockwise.

Connect the welder power cord to the AC power source. Turn the welder ON. Set the VOLTAGE switch.

25.

Setting the Wire Drive System

WARNING: Arc flash can injure eyes! To reduce the risk of arc flash, make certain that the

wire coming out of the end of the gun does not come in contact with the work piece, ground clamp or any grounded material during the drive tension setting process or arcing will occur.

1. Open the wire drive cover on the spool gun

2. Pull the trigger on the gun.

3. Turn the drive tension adjustment knob clockwise, increasing the drive tension until the wire seems to feed smoothly without slipping.

4. Close the wire drive cover on the spool gun.

5. When set correctly, there should be no slippage between the wire and the drive roller under normal conditions.

Adjusting the Spool Position

Before you begin welding, you may want to adjust the position of the spool so it is most

comfortable for

you. There are three positions to choose from. To change the position of the spool:

1. With a flat tipped screwdriver, loosen the screw which connects the spool casing to the gun.

2. Pull the casing far enough away from the gun to allow the casing to rotate.

3. Rotate the casing to one of the three available positions, making sure that the grooves on the gun are aligned with the grooves on the casing.

4. Push the casing and the gun back together.

5. With a flat tipped screwdriver, tighten the screw which connects the spool casing to the gun.

Operation

Description

The Forney 270 MIG welder is designed for use on jobs involving maintenance and fabrication. It is ideal for applications such as farming, automotive, and repairs. This transformer-based machine is powered from 230 V current and produces 270 A output. The acceptable wire diameters for use on this machine include .024”, .030”, .035”, and .045”. The spool sizes compatible with this machine are 4”, 8”, or 12” and should be loading clockwise, so the wire feeds from the top into the wire feeing system. This machine can weld materials up to 1/2” in thickness.

With welders in the digital series, thanks to a special electronic card it is possible to adjust externally the main welding parameters. The main purpose of these units is to make adjustment of these parameters very easy.

The microprocessor control handles the functions of the PC board that are viewed by means of LED’s while a digital display shows the parameters set and welding current. Units may be used either with the standard torch (supplied with them) or with the Spool Gun.

Thermal Overload Protection

WARNING: If the duty cycle of the welder is exceeded, a thermostat will automatically cut

the power to prevent the machine from overheating. If this should happen do not unplug the machine while it cools down. The thermostat will automatically reset itself and you can continue welding. The thermostat is a protective safety device and no harm will normally be done to the welder unless it is frequently over-loaded, in which case it may eventually become damaged.

Welding Preparation

• Attach the ground clamp to the bare metal to be welded, making sure of good contact;

• Make sure that the wire-roller groove in the roller corresponds to the diameter of the wire being used.

• Plug the machine into a suitable outlet. Completely open the gas cylinder valve. Adjust the gas pressure regulator to the correct

•

flow rate.

Factors to Consider for Best Welding Results

Some experience is required to adjust and use a MIG welder. In MIG welding two parameters are fundamental: the welding voltage and the wire speed. The resulting welding current is a result of these two settings.

• Set the voltage and wire feed controls to positions suitable for the thickness of the material to be welded. Welding current varies in relationship to wire feed speed. For low welding current output, the wire feed speed potentiometer should be set at the low end of the wire feed speed scale. Turning the wire feed speed control potentiometer clockwise will result in increased wire feed speed and welding current. Welding voltage is adjusted to match the wire feed speed (welding current). Progressively select higher voltage positions while increasing wire speed.

WWW.FORNEYIND.COM

Increasing welding voltage leads to a longer arc (without substantially affecting the current). Conversely, a decreased welding voltage results in a shorter arc (the current again is not substancially changed). A change in wire diameter results in changed parameters. A smaller diameter wire requires an increase in wire feed speed to reach the same current. If certain limits are exceeded, a satisfactory weld cannot be obtained. These are:

A) Feeding wire too fast (too high with regard to the welding voltage) results in pulsing within

the torch. This is because the wire electrode dips into the puddle and cannot be melted off fast enough.

B) Setting welding voltage to high (too high with regard to the wire feed speed), will result in

excessive and unstable arc. Increase the voltage even higher and the contact tip will burn.

C) Excessive wire speed can be corrected through the arc voltage increase. The limit of this

adjustment depends on the thickness of the material to be welded (a certain limit exceeded

will result in burn through). Place the torch on the joint you want to weld: the angle between the torch and the nozzle should be around 45°. The distance between the torch and the work piece should be 5-1/2”. Lower the face shield and press the torch trigger to start the arc. When the arc has struck, move the nozzle slowly from left to right along the joint. Adjust the wire feed speed until the arc makes a “crisp” sound (experience will help you to recognize the right sound).

A) Adjust using the trigger “MODE” key for the desired trigger mode. Press the “MODE” key

until the red LED lights up.

- 2T: two time welding (manual). The welding process starts when the torch trigger is pressed and stops when this is released.

- 4T: four time welding (automatic). The welding process starts when the torch trigger is pressed (after a pre-gas time), it continues even if torch trigger is released and stops when this is pressed and released once again after the post-gas time.

- Spot welding with timer: Automatic spot welder with timer. This process allows execution of repeated welding beads. The duration is set through the adjustment knob #66.

B) Adjust the wire speed knob #5.

The display can show numbers from 1 to 99 (1 being the minimum value and 99 the maximum value). The display shows the real welding current and the value of the parameter you selected and adjusted during the regulation phase. After welding, the display will show the welding current value for a maximum of 5 seconds.

Aluminum Welding

The machine should be set up for mild steel except for the following changes:

• 100% ARGON as welding protective gas.

• Ensure that your torch is set up for aluminum welding:

• The length of the torch cable should not exceed 10’ (it is advisable not to use longer torches).

Install a Teflon wire liner. Follow the instructions for changing the renewing of the wire liner.

•

• Ensure that drive rolls are suitable for aluminum wire.

• Use contact tips that are suitable for aluminum wire and make sure that the diameter of the

contact tip hole corresponds to the wire diameter that is going to be used.

For aluminium welding or for welding those materials such as CUSI and for applications where the power source needs to be placed far from the working area the spool gun is particularly suitable. This torch incorporates a wire feeding motor and the welding wire spool. The potentiometer integrated on the handle allows constant regulation of wire speed while an internal device in the welder recognizes and shows the spool gun connection when the green LED on the front of the welder lights up.

Maintenance & Servicing

General Maintenance

• Always weld clean, dry and well-prepared material.

• Hold gun at a 45° angle to the workpiece with nozzle about 1/2” from the surface.

• Move the gun smoothly and steadily as you weld.

• Avoid welding in very drafty areas. A weak, pitted and porous weld will result due to air

blowing away the protective welding gas.

• Keep wire and wire liner clean. Do not use rusty wire.

• Sharp bends or kinks in the welding cable should be avoided.

• Always try to avoid getting particles of metal inside the machine since they could cause short

circuits or other damage.

• If available, use compressed air to periodically clean the hose liner, especially when

changing wire spools. NOTE: Disconnect from power source when carrying out this operation.

• Using low pressure air (3/5 Bar=20-30 PSI), occasionally blow the dust from the inside of

the welder. This keeps the machine running cooler. NOTE: Do not blow air over the printed circuit board and electronic components.

• The wire feed roller will eventually wear during normal use. With the correct tension the

pressure roller must feed the wire without slipping. If the pressure roller and the wire feed roller make contact when the wire is in place between them, the wire feed roller must be replaced.

• Check all cables periodically. They must be in good condition and not cracked.
