WARNING
Mar ‘95
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.
1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.

ARC RAYS can burn.
4.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 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.
ELECTRIC SHOCK can
kill.
3.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.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
In addition to the normal safety precautions, if welding
must be performed under electrically hazardous
conditions (in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings or
scaffolds; when in cramped positions such as sitting,
kneeling or lying, if there is a high risk of unavoidable or
accidental contact with the workpiece or ground) use
the following equipment:
• 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 Items 6.c. and 8.
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. When
welding with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are
also required when welding on galvanized steel.
5.b.
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.c. 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.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. MSDS forms are available from
your welding distributor or from the manufacturer.
5.e. Also see item 1.b.

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.
CYLINDER may explode
if damaged.
7.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.
7.b. Always keep cylinders in an upright position securely
chained to an 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,

Mar ‘95
WELDING 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 sparks 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.

PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suivantes:
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien s’isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une grande
partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
d.Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
2. Dans le cas de travail au dessus du niveau du sol, se protéger
contre les chutes dans le cas ou on recoit un choc. Ne jamais
enrouler le câble-électrode autour de n’importe quelle partie
du corps.
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du rayonnement de l’arc et des projections quand on soude ou
quand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
l‘arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection libres
de l’huile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
8. S’assurer que la masse est connectée le plus prés possible
de la zone de travail qu’il est pratique de le faire. Si on place
la masse sur la charpente de la construction ou d’autres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant
d’opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de
l’électricité et aux recommendations du fabricant. Le dispositif
de montage ou la piece à souder doit être branché à une
bonne mise à la terre.
2. Autant que possible, I’installation et l’entretien du poste seront
effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la debrancher à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

MACHINE GROUNDING AND HIGH FREQUENCY INTERFERENCE PROTECTION
The welder must be grounded. See your local and national
electrical codes for proper grounding methods.
The high frequency generator, being similar to a radio
transmitter, can be blamed for radio, TV and electronic equipment interference problems. These problems
may be the result of radiated interference. Proper
grounding methods can reduce or eliminate radiated
interference.
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). Tape the
leads together when practical.
3. Be sure the torch and work cable rubber coverings
are free of cuts and cracks that allow high frequency leakage.
4. Keep the torch in good repair and all connections
tight to reduce high frequency leakage.
5. The work piece must be connected to an earth
ground close to the work clamp, using one of the
following methods:
Read entire installation section before starting
installation.
Safety Precautions
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 sides 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 V200-T cannot be stacked.
LIFTING AND MOVING
The Invertec V200-T has a lift handle on the top of the
case and also comes with a lift-carrying strap for convience.
TILTING
Place the machine directly on a secure, level surface.
The machine may topple over if this procedure is not
followed.
ENVIRONMENTAL RATING
• The machine has a protection rating of IP23. Keep
the machine dry when possible. Do not place it on
wet ground or in puddles.
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
• Turn the input power OFF at the
disconnect switch or fuse box
before working on this
equipment.
• Do not touch electrically hot
parts.
• Always connect the V200-T to a power supply grounded per the National Electrical
Code and any local codes.
WARNING
A-3
INSTALLATION
INVERTEC V200-T
A-3
a) A metal underground water pipe in direct con-
tact 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 cover and all screws securely in place.
7. Electrical conductors within 50 ft (15.2m) of the
welder should be enclosed in grounded rigid metallic conduit or equivalent shielding, wherever possible. Flexible metallic conduit is generally not suitable.
8. When the welder is enclosed in a metal building,
the metal building should be connected to several
good earth driven electrical grounds (as in 5 (b)
above) around the periphery of the building.
Failure to observe these recommended installation
procedures can cause radio or TV and electronic
equipment interference problems and result in unsatisfactory welding performance resulting from lost high
frequency power.
INPUT CONNECTIONS
Be sure the voltage, phase, and frequency of the input
power is as specified on the rating plate, located on
the rear of the machine.
Supply line entry provision is in the case rear panel.
A power cord is provided and wired into the machine.
Follow the power cord connection instructions.
Incorrect connection may result in equipment damage.
The Invertec V200-T is internally connected for a 460
volt input. The input switch has a lock pin which restricts
movement for 460 selection only. See figure A.1.
To connect the V200-T for 230 volt input, the following
input reconnect needs to be completed.
1. Disconnect the machine from the input supply.
2. Remove the wraparound by removing the shoulder strap brackets and wraparound screws.
3. Provide access to the line switch by bending the
insulation back.
4. When the insulation is bent back, two sleeved
leads will become visible.
5. Remove the sleeving from both leads.
6. Connect the large lead to push-on terminal
labeled “3” on the adjacent PC board.
7. Connect the small lead to terminal 15 of the line
switch.
8. Reposition insulation to cover line switch.
9. Re-install wraparound.
10. Move the lock pin to allow switch movement for
230 V selection only.
Connect the green w/ yellow strip lead to ground per
U.S. National Electrical Code. Connect the black and
white leads to power.

OUTPUT CONNECTIONS
Refer to Figure A.2 for the location of the output terminals.
A quick-disconnect system using Twist-MateTMcable plugs is
used for the welding cable connections. The electrode and
work cables will require these plugs. Refer to the relevant
instructions following for more information on connecting the
machine for either welding process.
OUTPUT CONNECTION FOR STICK
WELDING
First determine the proper electrode polarity for the electrode to be used. Consult the electrode data for this information. Then connect the output cables to the output terminals corresponding to this polarity. For instance, for DC(+)
welding, connect the electrode cable (which is connected to
the electrode holder) to the “+” output terminal and the work
cable (which is connected to the work clamp) to the “-” output terminal. Insert the connector with the key lining up with
the keyway, and rotate approximately 1/4 turn clockwise;
until the connection is snug. Do not over tighten.

(GTAW) welding. The Lincoln LA-9 (K859-1 or K859-5 only
with no gas valve) or LA-17 and LA-17V (K860-1 or K860-5
without gas valve and K860-9 or K860-13 with gas valve)
are recommended for use with these machines for this purpose; however, any similar TIG torch can be used. To attach
the Twist-Mate Plug to a Lincoln Torch, slide the rubber boot
onto the torch cable (enlarge the boot opening if necessary),
screw the fitting on the torch cable into the brass connector
snugly and slide the boot back over the brass connector.
Turn the Power Switch “OFF”. Connect the torch cable quick
connect plug into the DC- Output Receptacle on the front of
the welder and turn it clockwise until it is tight. This is a
quick connect terminal and also provides the gas connection
for the shielding gas to the torch.
To avoid receiving a high frequency shock, keep the TIG
torch and cables in good condition.
__________________________________________
Next, connect the work cable (which is connected to the
work clamp) to the “+” output terminal in the same way.
The machine can easily be switched between stick and TIG
welding at any time by simply swapping the stick (electrode)
and TIG (torch) cables, and reversing the connection polarity if required.

GENERAL DESCRIPTION
The Invertec V200-T is an industrial 200 amp arc
welding power source which utilizes single phase
input power, to produce constant current output. The
welding response of this Invertec has been optimized
for stick (SMAW) and TIG (GTAW). The unit is ideal
for industrial applications where portability is important.
OPERATIONAL FEATURES
The Invertec provides continuous total range output
current adjustment. Additionally, a “hot start” system
has been built into the welding current control, and
provides a higher striking current to assist ignition of
the arc.
WELDING CAPABILITY
The Invertec V200-T is rated at 200 amps, 28 volts, at
20% duty cycle on a ten minute basis. It is capable of
higher duty cycles at lower output currents. It is capable of 120 amps, 25 volts at at 100% duty cycle. If the
duty cycle is exceeded, a thermal protector will shut
off the output until the machine cools.
LIMITATIONS
The V200-T is not recommended for pipe thawing.
The V200-T should not be powered from the auxiliary
power supply of an engine welder. Special protection
circuits may operate causing loss of output.

Power Switch/Voltage Selector Switch - Controls
the power input to the machine. This rotating switch is
used to turn the machine on and off as well as to
select the input voltage. The switch is located on the
top right rear panel. When power is applied to the
machine the Power LED is on.
Welding Current Potentiometer - Potentiometer
used to set the value of the current required by the
welding process. This current setting will be displayed
on the Digital Display. When an Amptrol is used to
remotely control the welding current, this setting controls the maximum welding current when the Amptrol
is fully depressed.
Voltage out of spec/ Overheated LED - This LED
will light up when:
A) The input supply voltage is not within limits
pre-set for correct operation.*
B) The machine is overheated as detected by
the internal thermostat.
* Note that input voltages that exceed 20% of nominal
may cause internal damage to the machine.
Output Terminals - These quick disconnect terminals
provide connection points for the TIG Torch and work
cables or electrode and work cables. For TIG welding,
connect the torch to the DC- terminal and the work
cable to the DC+ terminal. For stick welding positive
polarity connect the electrode cable to the positive terminal and the work cable to the negative terminal. To
weld negative polarity reverse the electrode and work
cables.

Start/Crater Potentiometer - This potentiometer is
used to adjust the START CURRENT and CRATER
CURRENT for TIG welding only. This potentiometer
also adjusts the ARC FORCE when in STICK welding
mode.
Slope Up and Slope Down Time Potentiometers -
These potentiometers are used to adjust the Slope Up
and Slope Down Times respectively for TIG welding
only. The adjustable range for both timers is 0 to 10
sec.
Post Flow Time Potentiometer - This potentiometer
is used to adjust the gas postflow after the arc is extinguished when using a TIG process. The postflow time
is 0 - 50 sec.
Pulse Frequency/TIG Spot Timer Potentiometer -
This potentiometer is used to adjust the Pulse
Frequency when the TIG Process Switch is in the
PULSER position and to adjust the TIG Spot Time
when the TIG Process Switch is in the TIG SPOT
position. The Pulse Frequency range available is 300
Hz to 0.5 Hz. The Pulse Frequency on the V200-T is
actually adjusted in terms of the pulse period, which is
the inverse of the frequency. Increasing the knob (cw),
increases the period and because of their inverse
relationship, decreases frequency. Therefore, at the
maximum period setting (fully cw, or “10”) the frequency is at minimum (0.5 Hz) and at the minimum period
setting (fully ccw or “0”) the frequency is at maximum
(300 Hz). The spot time range is adjustable up to 10
sec.
Pulse Duration Potentiometer - This potentiometer
is active only when the TIG Process Switch is in the
PULSER position. It controls pulse duration or length
of time for pulse within the selected pulse frequency
(see above). Use this potentiometer to select the relative amount of peak and background current for the
selected overall frequency.
Pulse Amplitude Potentiometer - This potentiometer
is active only when the TIG Process Switch is in the
PULSER position at that time it controls pulse amplitude or height. Use this potentiometer to adjust the
background current as a percentage of the peak (or
maximum) current level.
TIG Process Switch - This switch is used to select
the type of TIG process to be performed. In the
PULSER position - Pulsed TIG welding, in the OFF
position - continuous TIG welding and in the TIG
SPOT position - spot TIG welding.
Welding Process Switch - This switch is used to
select the type of welding process to be performed. In
the 2S position - Two step TIG welding, in the 4S
position - 4 step TIG welding and in the STICK position - Stick welding. See the section on 2 step and 4
step explanation later in this section.
LOCAL/REMOTE Switch - This switch is used to
select where current can be adjusted. In the LOCAL
position current is controlled by the Welding Current
Potentiometer. In the REMOTE position any hand or
foot amptrol connected to the Remote Control
Connector will control the current setting. In both
modes, however, the current potentiometer on the
case front sets the maximum welding current available.
Gas Available LED - This LED will light when gas is
available in the TIG welding modes only.
Power LED - Indicates inverter is ON. After 5 minutes
without use, the inverter will go into a sleep mode and
the LED will go off. Any activity on the output will
immediately “Wake” the inverter up, the LED will come
back on and normal operation will resume.

OPERATING STEPS
WELDING IN TIG MODE
1. Connect the TIG torch and cable quick connect
plug to the DC- output receptacle. This receptacle
also contains an integral gas connection for the
torch. Connect the work cable to the DC+ receptacle and to the work piece.
2. Set the Welding Process Switch to “2S” when
using a hand or foot amptrol. When using an arc
start switch, “2S or “4S” can be used.
3. Set the TIG Process Switch to the desired position.
4. Connect an optional Amptrol or Arc Start Switch to
the Remote Control Connector
.
5. Turn on the cylinder gas valve and adjust the flow
regulator to obtain desired flow.
6. Turn the power switch to “230” or “460” as appropriate for your input voltage. NOTE: There will be a
0.5 second gas flow when the power is turned on.
7. Set the Current Control on the control panel to the
maximum desired amps.
8. Depress the Amptrol or Arc Start Switch to energize
the torch and establish an an arc with the work
piece.
NOTE: When the
TIG Process Switch
is set to
“2S” or
“4S” TIG position
, depressing the remote control will
start a 0.5 second gas pre-flow before energizing the TIG
torch. When the remote control is released the TIG torch
is de-energized and gas flow will continue for the set post
flow time (0 - 50 sec.).
REMOTE CONTROL OPERATION
A Foot Amptrol™ is optional with the V200-T for
remote current control while TIG welding. An optional
Hand Amptrol may also be used. An optional Arc
Start Switch may be used to start and stop the welding if no remote control of the current is desired. Refer
to the Accessories section of this manual.
Both the Hand and Foot Amptrol work in a similar
manner.
For simplicity, the following explanation will
refer only to “Amptrols”, meaning both Foot and Hand
models. The term “minimum” refers to a foot pedal in
the “up” position, as it would be with no foot pressure,
or a Hand Amptrol in the relaxed position, with no
thumb pressure. “Maximum” refers to a fully
depressed Foot Amptrol, or a fully extended Hand
Amptrol.
When the welder is in TIG modes activating the
Amptrol energizes the electrode terminal and varies
the output welding current from its minimum value of 1
amp, to the maximum value set by the Current Control
on the control panel. This helps eliminate accidental
high current damage to the work piece and/or tungsten, and gives a fine control of the current. When the
welder is in the stick mode a remote control has no
effect and is not used.
It is important to note that, in some cases, the tungsten will not start an arc at the minimum current
because the tungsten may be too large or cold. To
start an arc reliably, it is important to depress the
Amptrol far enough so that the machine output current
is near the tungsten operating range. For example, a
3/32” tungsten may be used on DC- to weld the full
range. To start the weld, the operator may have to
turn the current control up and depress the Amptrol
approximately 1/4 of the way down. Releasing the
Amptrol to its minimum position may not start the arc.
Also if the current control is set too low, the arc may
not start. In most cases, a large or cold tungsten will
not readily establish an arc at low currents. This is
normal. In DC-, the V200-T will start a 3/32, 2% thoriated tungsten electrode at 15 amperes provided the
electrode tip is properly grounded and not contaminated.

OPERATION
B-6
EXPLANATION OF 2 STEP AND 4
STEP MODES
(See figure B.2 and the explanations that follow)
2 STEP
2 Step mode can be used with either an arc start
switch or a hand or foot amptrol. The welding cycle
begins when the torch switch is held closed and ends
when the switch is released.
4 STEP
4 Step mode should only be used with an arc start
switch. The welding cycle begins when the torch
switch is pressed and then released. The cycle is
ended by a further press and release of the switch.
The pre-gas flow is followed by an increase in the
welding current from the level set by the Start/Crater
Current Potentiometer, to the value on the display
set with the Welding Current Potentiometer. The
rate of increase is determined by the setting of the
Slope Up Time Potentiometer.
The slope out phase begins with the release of the
torch switch in the 2 STEP mode or with a second
press of the switch in the 4 STEP mode.
During this phase, the welding current falls to the
crater current set on the Start/Crater Current
Potentiometer. The speed at which the welding current decreases is determined by the setting of the
Slope Down Time Potentiometer.
The power source comes equipped with a restart
capability. Any change required in the restart timing
can only be made by an authorized service center.
(See Figure B.2 - 4 Step Mode).
In the TIG-SPOT mode the UP/ DOWN-SLOPE controls and the PULSER function are disabled.
The welding cycle takes an "ON-OFF" type shape with
the welding current jumping very rapidly from 0 to the
nominal value.
PULSER FUNCTION
Pulsed welding is selected by using the TIG Process
Switch. In this mode the output is modulated to pro-
duce a series of current pulses. By this means precise control of heat input and penetration can be
achieved on critical applications. The pulse frequency,
duration and amplitude may be adjusted by means of
the respective potentiometers.

machine to sit for at least 5 minutes to allow time for
the process to take place.
------------------------------------------------------------------------
ROUTINE MAINTENANCE
1. Perform the following preventive maintenance
procedures at least once every thousand hours of
use. It is good practice to keep a preventive maintenance record; a record tag attached to the
machine works best.
2. Remove the machine cover (requires a 3 mm hex
key) after allowing the minimum 5 minute power
off requirement to let the input capacitors discharge.
Failure to observe this discharge time requirement
could result in severe electrical shock hazard.
------------------------------------------------------------------------
3. Keeping the machine clean will result in cooler
operation and higher reliability. Be sure to clean
the following areas with a low pressure air
stream.
• Printed circuit boards
• Power switch
• Fan blades
• Louvers
• Heat sink fins
• Output terminals
4. Examine capacitors for leakage or oozing. If any
leakage is noticed, take the unit to an authorized
Lincoln Field Service Shop.
5. Examine the case for breakage. Repair or
replace the case as required. Keep the case in
good condition to ensure that high voltage parts
are protected and correct spacings are maintained.
6. Install machine covers and fasteners.
REPLACEMENT OF INTERNAL
FUSE
The Invertec has additional protection provided to
some circuits through an internal fuse. For replacement of that fuse proceed as follows:
1. Turn off the power to the unit and remove the
input plug.
2. Allow the machine to stand for 5 minutes to let
the input capacitors discharge.
3. Remove the machine cover.
4. Replace the blown fuse with a new 0.5A 500V
slowblow fuse.
NOTE: If the fuse blows again after power is restored,
the cause could be an internal breakdown in
the power unit. In this case, take the unit to an
authorized Lincoln Field Service Shop.

The Procedure Handbook of Arc Welding
With over 500,000 copies of previous editions published
since 1933, the Procedure Handbook is considered by many to
be the “Bible” of the arc welding industry.
This printing will go fast so don’t delay. Place your
order now using the coupon below.
The hardbound book contains over 750 pages of welding
information, techniques and procedures. Much of this material
has never been included in any other book.
A must for all welders, supervisors, engineers and
designers. Many welding instructors will want to use the book
as a reference for all students by taking advantage of the low
quantity discount prices which include shipping by
4th class parcel post.
$15.00 postage paid U.S.A. Mainland
How To Read Shop Drawings
The book contains the latest information and application
data on the American Welding Society Standard Welding
Symbols. Detailed discussion tells how engineers and
draftsmen use the “short-cut” language of symbols to pass
on assembly and welding information to shop personnel.
Practical exercises and examples develop the reader’s
ability
to visualize mechanically drawn objects as they will appear
in their assembled form.
187 pages with more than 100 illustrations. Size 8-1/2” x
11”
Durable, cloth-covered board binding.
$4.50 postage paid U.S.A.

such as distortion; and supplemental information on arc
welding applications, speeds and costs. Practice materials,
exercises, questions and answers are suggested for each
lesson.
528 pages, well illustrated, 6” x 9” size, bound in simulated,
gold embossed leather.
