GENERAL 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 weld-
ing (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.
INCLUDED EQUIPMENT
For GTAW (TIG Welding):
• TIG connector (Twistmate adaptor)
• Strain relief boot
For SMAW (Stick Welding):
• Electrode holder with cable and Twistmate plug
For Installation and startup:
• Work Cable and Clamp
WELDING CAPABILITY
The Square Wave TIG 175 is rated at 150 amps, 16
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.

ELECTRIC SHOCK
can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
•
Insulate yourself from work and ground.
• Always wear dry insulating gloves.
•
Read and follow “Electric Shock Warnings”
in the Safety section if welding must be per-
formed under electrically hazardous condi-
tions such as welding in wet areas or on or
in the workpiece.
FUMES AND GASES
can be dangerous.
• Keep your head out of fumes.
• Use ventilation or exhaust to
remove fumes from breathing
zone.
WELDING SPARKS
can cause fire or
explosion
• Keep flammable material away.
• Do not weld on containers that
have held combustibles.
ARC RAYS
can burn.
• Wear eye, ear and body
protection.
