SAFETY PRECAUTIONS
Read and understand this entire section before operat- ing the machine.
WARNING
ELECTRIC SHOCK 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.
WELDING SPARKS
can cause fire or 
explosion
•Keep flammable material away.
•Do not weld on containers that have held combustibles.

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.
