B-1 OPERATION B-1
PRODUCT DESCRIPTION
The SQUARE WAVE™ TIG 175 is a constant current,
single range AC/DC TIG (GTAW) arc welding power
source with built-in arc starter / stabilizer. It also has
stick welding (SMAW) capability.
The SQUARE WAVE™ TIG 175 is recommended for
the TIG (GTAW) and stick (SMAW) welding processes
within its output capacity of 10 to 175 amps, on both
AC and DC polarity.

WELDING CAPABILITY
The SQUARE WAVE™ TIG 175 is rated at 150 amps,
15 volts, at 25% duty cycle on a ten minute basis. It is
capable of higher duty cycles at lower output currents.
It is capable of 175 amps, 27 volts at a lower duty
cycle. If the duty cycle is exceeded, a thermal protec-
tor will shut off the output until the machine cools.
