Tig Welding - Vulcan-Hart OMNIPRO 220 Owner's Manual & Safety Instructions

TIg Welding

TO pREVENT SERIOUS INJURy ANd dEATH:
do not weld without grounding clamp.
When the operator is not holding the Torch, it must be sitting on a nonconductive, nonflammable surface.
Only hold TIg Rod with an electrically insulated welding glove.
TO pREVENT dEATH FROM ASpHyXIATION:
do not open gas without proper ventilation. Fix gas leaks immediately. Shielding gas can displace
air and cause rapid loss of consciousness and death. Shielding gas without carbon dioxide can be
even more hazardous because asphyxiation can start without feeling shortness of breath.
NOTIcE: TIG welding is a complicated process,
requiring experience and skill to achieve
successful results. Training beyond the scope of
this manual is required to TIG weld properly.
1. Open gas cylinder's valve all the way.
2. Set Flow Gauge to SCFH value indicated on the
Settings Chart on the inside of the Welder door.
3. Turn the Power Switch to the OFF position, then
plug the Welder into a properly grounded, GFCI
protected, 120 V AC (20 amp rated) outlet or
