Abstract:
1. Apparatus for remote control of welding wire feeding speed and welding current parameters in a welding device comprising: A welding torch including a variable trigger control and switching means to select which said parameter is varied by said trigger control; a wire speed control relay operatively connected to said switching means and said wire feed speed control, a current control relay operatively connected to said switching means and said welding current control; a master wire speed controller operatively connected to said wire speed control relay; a master welding current controller operatively connected to said current control relay; wherein said switching means selectively engages either said variable wire speed feed control, said variable welding current control, or both to be controlled by said variable trigger control; wherein further the non-selected control is fixed to a preselected value set by said master wire speed and said current control.
