ABSTRACT:
The control unit comprises an elongated body having a forward torch mounting portion. Rearwards of the torch the body houses a linear potentiometer which includes an upstanding control arm for its movable contact. An off-on switch is located within said body, in a position to be contacted and operated by the control arm. A thumb button controlled sliding control member is attached to the control arm. In use, the user grips the mid portion of the body and places his thumb on the thumb button. He uses a simple linear movement of his thumb to both control the linear potentiometer, for varying the welding current, and to operate the off-on switch, for turning the arc welding machine on and off.
