Read and understand the following safety highlights. For additional safety information, it is strongly recommended that you purchase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box 351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.
BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
FOR ENGINE POWERED EQUIPMENT.
1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.
1.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors.
1.c. Do not add the fuel near an open flame welding arc or when the engine is running. Stop the engine and allow it to cool before refueling 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.
1.d. Keep all equipment safety guards, covers and devices in position and in good repair.Keep h
ands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repairing equipment.
1.e. In some cases it may be necessary to remove safety guards to perform required maintenance. Remove guards only when n
ecessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts.
1.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.
1.g. To prevent accidentally starting gasoline engines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate.
1.h. To avoid scalding, do not remove the radiator pressure cap when the engine is
hot.
ELECTRIC AND MAGNETIC FIELDS MAY BE DANGEROUS
2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines
2.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding.
2.c. Exposure to EMF fields in welding may have other health effects which are now not known.
2.d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit:
2.d.1. Route the electrode and work cables together - Secure them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and work cables. If the electrode cable is on your right side, the work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close as pos­sible to the area being welded.
2.d.5. Do not work next to welding power source.

• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically “hot”.
3.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.
3.e. Ground the work or metal to be welded to a good electrical (earth) ground.
3.f. Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.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.
3.i. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.
3.j. Also see It ems 6.c. and 8.
ARC RAYS CAN BURN.
4.a. Use a shield with the proper filter and cover plates to protect your e
yes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.
4.c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
FUMES AND GASES CAN BE DANGEROUS.
5.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. +(09(.',0*

5. b. The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits.
5.c. Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritating products.
5.d. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.
5.e. 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. MSDS forms are available from your welding distributor or from the manufacturer.
5.f. Also see item 1.b.

SAFETY
Page 5
WELDING AND CUTTING SPARKS CAN CAUSE FIRE OR EXPLOSION.
6.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 s
parks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations. Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1) and the operating information for the equipment being used.
6.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.
6.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 vapors from substances inside. They can cause an explosion even though they have been “cleaned”. For information, purchase “Recommended Safe Practices for the Preparation for Welding and Cutting of Containers and Piping That Have Held Hazardous Substances”, AWS F4.1 from the American Welding Society (see address above).
6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode.
6.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.
6.g. Connect the work cable to the work as close to the welding area as practical. 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.
6.h. Also see item 1.c.
6.I. Read and follow NFPA 51B “ Standard for Fire Prevention During Welding, Cutting and Other Hot Work”, available from NFPA, 1 Batterymarch Park, PO box 9101, Quincy, Ma 022690-9101.
6.j. Do not use a welding power source for pipe thawing.
CYLINDER MAY EXPLODE IF DAMAGED.
7.a. Use only compressed gas cylinders containing t
he 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 m
aintained in good condition.
7.b. Always keep cylinders in an upright position securely chained to a
n undercarriage or fixed support.
7.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.
7.d. Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.
7.g. Read and follow the instructions on compressed gas cylinders, associated equipment, and CGA publication P-l, “Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association 1235 Jefferson Davis Highway, Arlington, VA 22202.
FOR ELECTRICALLY POWERED EQUIPMENT.
8.a. Turn off input power using the disconnect switch at the fuse box before working on the equipment.
8.b. Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manufacturer’s recommendations.
8.c. Ground the equipment in accordance with the U.S. National Electrical Code and the manufacturer’s recommendations.

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 affect many kinds of electrical equipment; other nearby welding equipment, radio and TV reception, 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.

The 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 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. In other cases it could involve construction of 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 authorized by a person who is competent to access whether the changes will increase the risk of injury, e.g., by allowing parallel welding current return paths which may damage the earth circuits of other equip­ment.

Before installing welding equipment the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account:
a. other supply cables, control cables, signaling 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 equipment, e.g., guarding of industrial equipment;
e. the health of the people around, e.g., the use of pacemakers and
hearing aids;
f. equipment used for calibration or measurement
g. the immunity of other equipment in the environment. The user shall
ensure that other equipment being used in the environment is compatible. This may require additional protection measures;
h. the time of day that welding or other activities are to be carried out.
T
he 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.

Mains Supply
Welding equipment should be connected to the mains supply a
ccording to the manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of 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 adjustments covered in the manufacturers instructio ns. In particular, the spark gaps of arc striking and stabilizing 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 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, not connected to earth because of its size and position, e.g., ships 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 the work piece 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 a direct connection to the work piece, 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.

SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Only qualified personnel should perform this installation.
• Turn the input power OFF and unplug the machine from the receptacle before work­ing on this equipment. Allow machine to sit for 5 minutes
minimum to allow the power capacitors to discharge before working inside this equipment.
Insulate yourself from the work and ground.
Always wear dry insulating gloves.
• Always connect the V205-T to a power supply grounded according to the National Electrical Code and local codes.
-------------------------------------------------------
SELECT SUITABLE LOCATION
The Invertec will operate in harsh environments. Even so, it is important that simple preventative measures are followed in order to assure long life and reliable operation.
• The machine must be located where there is free circulation of clean air such that air movement in the back and out the front will not be restricted.
• Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown.
STACKING
The Invertec V205-T DC & V205-T AC/DC can not be stacked.
TILTING
Place the machine directly on a secure, level surface. The machine may topple over if this procedure is not followed.
ENVIRONMENTAL AREA
Keep the machine dry. Do not place it on wet ground or in pud­dles.
MACHINE GROUNDING AND HIGH FREQUENCY INTERFERENCE PROTECTION
The Capacitor Discharge Circuit used in the high frequency gener­ator, may cause many radio, TV and electronic equipment interfer­ence problems. These problems may be the result of radiated i
nterference. Proper grounding methods can reduce or eliminate
radiated interference.
The Invertec V205-T DC & V205-T AC/DC have been field tested under recommended installation conditions. It complies with FCC allowable limits for radiation.
Radiated interference can develop in the following four ways:
1. Direct interference radiated from the welder.
2. Direct interference radiated from the welding leads.
3. Direct interference radiated from feedback into the power lines.
4. Interference from re-radiation of “pickup” by ungrounded metallic objects.
Keeping these contributing factors in mind, installing equipment per the following instructions should minimize problems.
1. Keep the welder power supply lines as short as possible and enclose as much of them as possible in rigid metallic conduit or equivalent shielding for a distance of 50 feet (15.2m). There should be good electrical contact between this conduit and the welder case ground. Both ends of the conduit should be con­nected to a driven ground and the entire length should be con­tinuous.
2. Keep the work and electrode leads as short as possible and as close together as possible. Lengths should not exceed 25 ft (7.6m).
WARNING

INSTALLATION
V
205-T DC & V205-T AC/DC
3. Be sure the torch and work cable rubber coverings are free of cuts and cracks that allow high frequency leakage. Cables with high natural rubber content, such as Lincoln Stable-Arc
®
b
etter resist high frequency leakage than neoprene and other
synthetic rubber insulated cables.
4. Keep the torch in good repair and all connections tight to reduce high frequency leakage.
5. The work terminal must be connected to a ground within ten feet of the welder, using one of the following methods.
a) A metal underground water pipe in direct contact with
the earth for ten feet or more.
b) A 3/4” (19mm) galvanized pipe or a 5/8” (16mm) solid
galvanized iron, steel or copper rod driven at least eight feet into the ground.
The ground should be securely made and the grounding cable should be as short as possible using cable of the same size as the work cable, or larger. Grounding to the building frame electrical conduit or a long pipe system can result in re-radiation, effectively making these members radiating antennas.
6. Keep all panels securely in place.
7. All electrical conductors within 50 ft (15.2m) of the welder should be enclosed in grounded, rigid metallic conduit or equivalent shielding. Flexible metallic conduit is generally not suitable.
8. When the welder is enclosed in a metal building, several earth driven electrical grounds connected (as in 5b above) around the periphery of the building are recommended.
Failure to observe these recommended installation procedures can cause radio or TV interference problems.
INPUT CONNECTIONS
Be sure the voltage, phase, and frequency of the input power is as specified on the rating plate, located on the bottom of the machine.
ELECTRIC SHOCK can kill.
• Have a qualified electrician install and service this equipment.
• Turn the input power OFF and unplug the machine from the receptacle
before working on this equipment.
• Allow machine to sit for 5 minutes
minimum to allow the power capacitors to discharge before working inside this equipment.
• Do not touch electrically hot parts.
• Machine must be plugged into a receptacle that is ground­ed according to the National Electrical Code and local codes.
• Do not remove or defeat the purpose of the power cord ground pin.
------------------------------------------------------------------
RECONNECT PROCEDURE
The Invertec V205-T DC & V205-T AC/DC auto reconnect to either 115V or 230V supply.
This machine is capable of operating within the following input voltage ranges (Table A.1):
TABLE A.1
Fuse the input circuit with time delay fuses or delay type¹circuit breakers. Using fuses or circuit breakers smaller than recom­mended may result in “nuisance” shut-offs from welder inrush currents even if not welding at high currents.
The Invertec Power Source is recommended for use on an individ­ual branch circuit.
¹
Also called “inverse time” or “thermal/magnetic” circuit breakers. These circuit breakers have a delay in tripping action that decreases as the magnitude of the current increases.

230V INPUT
The equipment is provided with a 230/115V cable, 6.6ft.(2m) in l
ength with a 230V 6-50P attachment plug.
The Invertec V205-T performs best when connected to 230VAC inputs. This input allows full output of the machine (200 amps).
115V INPUT
A suitable 115V attachment plug must be installed on the power cord to use the V205-T with a 115V input supply. The rated output of the V205-T is available when connected to a 30A branch circuit. When connected to a branch circuit with lower amp rating, lower welding current and duty cycle must be used. An output guide is provided below. The values are approximate and must be adjusted downward if the fuse or circuit breaker trips off. Other loads on the circuit and fuse/circuit breaker characteristics will affect the available output. Do not exceed these welding conditions:
15A branch circuit
10% duty cycle Stick: 75A TIG: 105A
20A branch circuit
10% duty cycle Stick: 90A TIG: 130A
ATTACHMENT PLUG INSTALLATION
Connect the white (neutral) wire under terminal clamp with silver screw, and black (hot) wire under terminal clamp with brass screw. Connect green wire under terminal clamp with green screw.
Failure to wire as instructed may cause personal injury or damage to equipment. To be installed or checked by an electrician or qualified person only.
------------------------------------------------------------------
In all cases, the green or green/yellow grounding wire must be con­nected to the grounding pin of the plug, usually identified by a green screw.
Attachment plugs must comply with the Standard for Attachment Plugs and Receptacles, UL498.
The product is considered acceptable for use only when an attach­ment plug as specified is properly attached to the supply cord.
For use on engine drives, keep in mind the above input draw restrictions and the following precaution.
ENGINE DRIVEN GENERATOR
The Invertec V205-T DC & V205-T AC/DC can be operated on engine driven generators as long as the 230 volt auxiliary meets the following conditions:
• The AC waveform peak voltage is below 400 volts.
• The AC waveform frequency is between 45 and 65Hz.
The following Lincoln engine drives meet these condi-tions when run in the high idle mode:
• Ranger 250, 250 LPG, 305 G, 305 D
*
• Vantage 300, 400, 500 & Air Vantage 500
* Some engine drives do not meet these conditions (e.g. Miller Bobcats, etc). Operation of the Invertec V205-T AC/DC is not rec­ommended on engine drives not conforming to these conditions. Such drives may deliver unacceptably high voltage levels to the Invertec power source.
*
Ranger and Vantage Engine Drives require the full KVA Adapter Kit (K1816-1)

WELDING CAPABILITY
T
he Invertec V205-T DC & V205-T AC/DC is rated at 200 amps, 18 volts, at 40% duty cycle on a ten minute basis. It is capable of higher duty cycles at lower output currents. It is capable of 140 amps, 15.6 volts at at 100% duty cycle. If the duty cycle is e
xceeded, a thermal protector will shut off the output until the machine cools. See Technical Specifications in A-1 for other rated outputs.
The Invertec V205-T is recommended for stick welding with such popular electrodes as Fleetweld 5P and 5P+ (E6010), Fleetweld 35 (E6011), Fleetweld 37 (E6013), Fleetweld 180 (E6011) and Excalibur 7018.
LIMITATIONS
The V205-T is not recommended for pipe thawing.
REAR CONTROL PANEL (FIGURE B.1)
• I1: Off/On switch turns on the electric power to the welder.
It has two positions, "O" off, and "I" on.
------------------------------------------------------------------
* With "l1" in the "I" (ON) position, the welding machine is opera-
tional and there is voltage between the positive (+) and negative (-) Terminals in stick welding. In TIG, the welding process needs a trigger closure command at the remote control connection.(Usually via an Arc Start Switch or Foot Amptrol)
* The welder is connected to the supply even if the “l1” (Power
Switch) is in the "O" (Off) position, and therefore there are elec­trically live parts inside the power source. Carefully follow the instructions given in this manual.

8. Tig Trigger Sequences - For the V205-T AC/DC, TIG welding
can be done in either the 2-step or 4-step mode which is selected with the Trigger Mode Push Button.
2-Step Sequence
With the Trigger Mode switch in the 2-step position, the follow­ing welding sequence will occur. This sequence is shown in (2-
step diagram 1)
1. Press and hold the Arc Start Switch to start the sequence.
The machine will open the gas valve to start the flow of the shielding gas. After a 0.5 second preflow time, to purge air from the torch hose, the output of the machine is turned ON. At this time the arc is started.
After the arc is started the output current will be increased from the start current to the welding current. Both the start current and increase, or upslope time are presettable. The default start current is 15 amps and the default upslope time is 0.2 seconds.
2. Release the Arc Start Switch to stop welding.
The machine will now decrease the output current at a con­trolled rate, or downslope time, until the Finish current, (also commonly referred to as Crater Current) is reached and the out­put of the machine is turned OFF. Both the Downslope Time and the Finish Current are can be preset.
After the arc is turned OFF, the gas valve will remain open to continue the flow of the shielding gas to the hot electrode and work piece. The duration of this postflow shielding gas is adjust­ed by the Postflow Parameter.
Possible variations of this standard sequence is shown in (2 step diagram 2). It is possible to press and hold the TIG torch trigger a second time during downslope to restart. After the trigger is pressed the output current will increase to the welding current. This operation is shown in (2 step diagram 2).
4-Step Sequence
With the 4-step Selected, the following welding sequence will occur.
1. Press and hold the Arc Start Switch to start the sequence.
The machine will open the gas valve to start the flow of the shielding gas. After a 0.5 second preflow time, to purge air from the torch hose, the output of the machine is turned ON. At this time the arc is started.
After the arc is started the output current will be at the Start cur­rent. This condition can be maintained as long or as short as necessary.
If the Start current is not necessary, do not hold the TIG torch trigger as described at the beginning of this step. Instead, quick­ly press and release the trigger. In this condition, the machine will automatically pass from Step 1 to Step 2 when the arc is started.
2. Release the TIG torch trigger to start the main part of the weld.
The output current will be increased from the start current to the welding current. Both the start current and increase, or upslope time are presettable. The default start current is 15 amps and the default upslope time is 0.2 seconds.
3. Press and hold the TIG torch trigger when the main part of the weld is complete.
The machine will now decrease the output current at a con­trolled rate, or downslope time, until the Finish current is reached. Both the Downslope Time and the Finish Current are presettable. This Finish current can be maintained as long or as short as necessary.

- Press the SETUP/Parameter "Item 4" push button again to pass to another parameter, or wait five seconds and the Weld Current LED will come on again.
14. VRD (Voltage Reduction Device) Status Lights - Voltage reduction device can be enabled from the set-up menu and an output voltage limit can be set that reduces the output open circuit voltage when not welding to that limit. If enabled when the machine is sitting idle the Green VRD on light will illuminate to indicate the voltage is reduced below the set limit. If the VRD device is not enabled (factory default) from the set up menu or while welding the red VRD off light will illuminate.
Note: The green VRD on light will illuminate in TIG mode until the output is
triggered even when VRD is disabled.

DC TIG WELDING
(see FIGURE B.3) The TIG (Tungsten lnert Gas) welding process is based on the presence of an electric arc between a non-consumable electrode (pure or alloyed tungsten with an approximate melting tempera­ture of 3370°C) and the workpiece. An inert gas (typically argon) atmosphere protects the weld pool.
To avoid inclusions of tungsten in the joint, the electrode should not contact the workpiece. For this reason the arc is started through a Hi. Freq. generator.
For situations requiring no Hi. Freq., Touch Start Tig reduces the short-circuit current to keep tungsten inclusions to the minimum.
To improve weld bead quality at the end of the weld it is important to carefully control the downslope of current and ensure proper gas coverage over the weld.
FIGURE B.3
WELDING POLARITY
DC El ectrode Negative Polarity (Direct Current S traight Polarity)
(see Figure B.4) While Welding, there is a continuous flow of electrons from the electrode to the workpiece.
This is the most used polarity, ensuring limited wear of the elec­trode, since the majority of the heat concentrates on the anode (workpiece). Narrow and deep welds are obtained with high travel speeds.
Most materials, with the exception of aluminum and magnesium, are welded with this polarity.

n this case, there is a continuous flow of electrons from the work­piece to the electrode. The reverse polarity is used for welding alloys covered with a layer of refractory oxide.
With this polarity the electrode functions as anode and is subject­ed to a high degree of heat; the workpiece is bombarded by posi­tive ions sent from the electrode which break the surface oxide.
In Electrode Positive Polarity, high currents cannot be used, since they would cause an excessive wear of the electrode.
NOTE: (The Invertec V205-T DC & V205-T AC/DC cannot be used for Electrode Positive TIG welding without special adapters.)
FIGURE B.5
D.C.- Pulsed TIG
(see Figure B-6)
The use of pulsed direct current allows better control of the weld pool during certain operating conditions.
When compared with traditional TIG welding performed at the same average current, pulsed welding results in a smaller heat affected zone which results in fewer deformations and reduced chance of cracking and gas entrapment.
Increasing the frequency constricts the arc, increases stability and improves weld quality.
FIGURE B.6
A.C. (Alternating Current) (AC/DC model only)
(
see Figure B.7)
Alternating Current welding is typically used for Tig welding alu­minum (and its alloys) or magnesium. The polarity alternates between Electrode Positive and Electrode Negative (EN). During the positive half-wave the oxide is broken. During the negative h
alf-wave, the electrode cools, the workpiece melts and penetra-
tion occurs.

OPERATION
STEEL TIG WELDING
The TIG process is very effective for welding both carbon steel and a
lloy steel, especially in applications requiring precision results. DC Electrode Negative Polarity is required. Since this process does n
ot include the removal of impurities, proper cleaning and prepa­ration of the edges is required.
FILLER MATERIAL:
T
he filler rods must deposit welds with mechanical characteristics appropriate for the application.
COPPER TIG WELDING
Since TIG welding is a process characterized by high heat concen­tration, it is particularly suitable for welding materials with high thermal conductivity, like copper. As with steel, the DC Electrode Negative Polarity is employed, with argon as protective gas. Considering the fluidity of molten copper, the use of backup sup­port may prove useful.
FILLER MATERIAL:
In order to avoid the oxidation of the molten material, filler materi­als containing phosphorus, silicon or other deoxidating materials are typically us ed . The mechanical properties can also be improved through the use of silver.
TIPS FOR AC TIG WELDING
(AC/DC model only)
AC Inverter TIG power sources offer two significant advantages over conventional Silicon Controlled Rectifier (SCR) / transformer power sources:
1. The AC wave balance can be set to a higher percentage elec­trode negative which minimizes tungsten heating and erosion.
2. The AC frequency can be varied to "focus" the arc. Increasing the AC frequency above 60Hz will narrow the cone shape arc from the tungsten’s tip. Decreasing the AC frequency below 60Hz will broaden the cone shape arc from the tungsten’s tip.
The two above benefits can be used to maintain a tight focus of the arc for precise heat control and tight joint access. Because of the AC inverters abilities in these areas the following recommen­d
ations are made as a starting point:
• A 2% Thoriated tungsten is recommended instead of the Pure tungsten that is normally recommended for AC we lding. Thoriated tungstens emit electrons easier and therefore will improve starting.
• Sharpen the tungsten to a point. Normally it is recommended to pre-ball a pure tungsten when AC welding with a convention­al power source. However, the AC inverter with it’s extended AC balance control minimized tungsten heating thus allowing for a pointed tungsten to be used.
• Set the AC Balance control to maximum 85% electrode nega­tive. This can be reduced if the material welded is heavily oxi­dized, however starting at maximum and adjusting to less is desired.
• Set the AC Frequency in the 100 to 120 Hz range. This is a "Sweet Spot" for most aluminum applications.

OPERATION
PROTECTIVE GAS
Both argon and helium work when welding aluminum. Argon is preferred, due to its lower cost and consumption rate. This gas a
lso tends to stabilize the arc, thus making it easy to operate. For some applications, however, the use of helium, or argon-helium blends, is recommended due to better weld penetration and faster travel speed. Helium is especially suitable for welding thick work­pieces. The recommended gas flow rates are shown in table 5.
TABLE 5
TIPS FOR IMPROVED TIG STARTING
1. Start Current:
For the best AC or DC TIG starting characteristics it may be neces­sary to adjust the start current on the front panel depending on the tungsten size. In general, larger tungsten requires more energy to establish an arc than smaller tungsten. As an initial guideline, set the start current according to the following recommendations:
Tungsten Size (in.) Start Current (Amps)
0.020, 0.040 1/16th 6-10 Amps 3/32 th 10-12 Amps 1/8th 12-15 Amps
2. DC Strike Current:
Aside from start current, DC strike current can also be adjusted from the set-up menu to get a hotter or softer start when DC TIG welding. Strike current is an initial spike of current that lasts a few milliseconds before the machine goes to start current. In general, the factory default of 40 amps works for most applica­tions. If welding on very thin materials with small diameter tung­sten, strike current can be turned down to minimize burning through the weld material. Like wise for larger diameter tungsten strike current can be turned up to put more energy in the tung­sten.
3. AC TIG Start Power:
For AC TIG welding AC start power can be adjusted from the set­u
p menu to aid starting if required. The V205-T AC/DC when set to AC TIG will try to initiate the arc with positive polarity until the arc is established. Positive polarity puts more energy into heating the tungsten but the drawback is that is can cause the tungsten to ball excessively or to super heat. Note super heating of the tung­sten can be noticed if the tungsten is glowing red or orange during starting. Start Power can be adjusted within two ranges:
Range Mode
0.5 to 1 Manual Setting
1.2 to 5.0 Incremental setting
If start power is set within the incremental range mode, the machine tries to start electrode positive at a relative setting of 1. If the arc fails to establish it will repeat the start sequence each time by incrementing the amount of electrode positive energy by 10% more (0.1) up to the start power limit setting or until the arc estab­lishes. For comparison a start power limit of 2 if reached will have twice the energy of the starting point of 1. If the tungsten has too much of a ball on it or appears to be super heating during starts the start power limit can be turned down. In the manual setting range, the start power will not keep incrementing up to a limit. Instead the start power stays at whatever level is set. For example a setting of 0.5 will start the machine with half the normal starting energy of 1.
