mig welding? Answered

if you are mig welding and you run out of gas, and you shut the valve off is the line to the welding still pressurized?


If you ran out of gas while you were welding, in theory, the line to the gun would not be pressurized. One way to be sure is to bleed the line of all remaining gas. To do that, close the valve to the tank, and then with the welder on, squeeze the trigger AWAY from your grounded work surface.
