METHOD OF CONVERTING A GAS TUNGSTEN ARC WELDING SYSTEM TO A PLASMA WELDING SYSTEM

摘要

A welding system includes a gas tungsten arc welding power source having a welding arc contactor, a plasma welding torch, and a gas console that supplies gases to the plasma welding torch. The welding system also includes a coolant flow switch connected in series with the welding arc contactor. Power is not provided from the gas tungsten arc welding power source to the plasma welding torch when the coolant flow switch is not actuated.
