ABSTRACT:
A welding torch handle including electrical control means thus enabling a welder, by the control on the handle, to vary the welding current supplied to an electrode in the torch head fitted to the handle. The handle is characterized by employing a linearly actuated control that can continuously vary current applied to the electrode from 0 amps to the full setting on the welding power supply. This control eliminates foot, hand held, or motor driven controls and provides convenient single-handed current control by the welder.
