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.
3
SAFETY
ELECTRIC SHOCK
CAN KILL.
3.a. The electrode and work (or ground) circuits are
e
lectrically “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.

• 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. +(09(.',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
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.

SAFETY
ELECTROMAGNETIC
COMPATIBILITY (EMC)
Products displaying the CE mark are in conformity with European
Community Council Directive of 3 May 1989 on the approximation of
the laws of the Member States relating to electromagnetic compatibility (89/336/EEC). It was manufactured in conformity with a national
s
tandard that implements a harmonized standard: EN 60974-10
Electromagnetic Compatibility (EMC) Product Standard for Arc Welding
Equipment. It is for use with other Lincoln Electric equipment. It is
designed for industrial and professional use.
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).

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.
