GENERAL DESCRIPTION
The Invertec V205-T AC/DC 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 impor-
tant.
The Invertec V205-T AC/DC is a power source that
can perform the following types of welding with excel-
lent results:
TIG (with high frequency or Touch Start Tig Starting).
• TIG AC with square, sinusoidal and triangular
waveforms
• Tig DC
The following items can be connected to the 6 pin
socket on the front panel:
• Remote control potentiometer for Stick welding.
•
Remote Foot Amptrol or Hand Amptrol
• Arc Start Switch
NOTE: See Accessories section of this manual for
product numbers and complete description.
WELDING CAPABILITY
The Invertec 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 exceeded, a thermal protec-
tor 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 weld-
ing with such popular electrodes as Fleetweld 35,
Fleetweld 37, Fleetweld 180 and Excalibur 7018.
LIMITATIONS
The V205-T is not recommended for pipe thawing.
