WELDING CAPABILITY
The SQUARE WAVE TIG 175 PRO 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 out-
put currents. It is capable of 175 amps, 27 volts at a
lower duty cycle. If the duty cycle is exceeded, a ther-
mal protector will shut off the output until the machine
cools.
