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
better 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 ground-
ed 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):
NOMINAL
115V
208V / 230V
Fuse the input circuit with time delay fuses or delay type¹ circuit
breakers. Using fuses or circuit breakers smaller than recom-
mended 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 individ-
ual 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.
