can kill.
• Do not touch electrically live parts
or electrode with skin or wet cloth-
ing.
• Insulate yourself from work and
ground.
• Always wear dry insulating gloves.
• Read and follow "Electric Shock
Warnings" in the Safety section if weld-
ing must be performed under electrical-
ly hazardous conditions such as weld-
ing in wet areas or on or in the work-
piece.
FUMES AND GASES
can be dangerous.
• Keep your head out of fumes.
• Use ventilation or exhaust to
remove fumes from breathing
zone.

OPERATION

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.

INCLUDED EQUIPMENT

• Work Cable and Clamp.
• Input Cord with NEMA 6-50P Input Plug.
For GTAW (TIG Welding):
• TIG torch, (17 Series) with:
• 12.5 ft (3.8m) one-piece cable.
• 3/32" Collet body.
• 3/32" Collet.
• 3/32" x 7" 2% ceriated Tungsten Electrode.
• Long backcap.
• 7/16" Diameter Alumina gas Nozzle.

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.
