GENERAL DESCRIPTION
The Invertec V205-T DC & V205-T AC/DC are indus-
trial 200 amp arc welding power sources that utilize
single phase input power, to produce constant current
output. The welding response has been optimized for
stick (SMAW) and TIG (GTAW). The units are 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
excellent results:
• TIG AC with square, sinusoidal and triangular
waveforms.
• TIG DC (with high frequency or Touch Start TIG
Starting)
• Stick DC
The Invertec V205-T DC is a power source that can
perform the following types of welding with excellent
results:
• TIG DC (with high frequency or Touch Start TIG
Starting)
• Stick 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 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 out-
put currents. It is capable of 140 amps, 15.6 volts at at
100% duty cycle. If the duty cycle is exceeded, 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 weld-
ing 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.
