Abstract:

A motor controlled rheostat assembly for a welding torch is disclosed. The assembly comprises a power source, a rheostat having a motor operatively connected thereto for controlling power to the welding torch, the rheostat being electrically connected to the power source and disposed remotely from the welding torch, a switch, connectable to the welding torch, having a first position and a second position, wherein when the switch is depressed toward the first position the motor rotates in a first direction to increase the power to the torch, and when the switch is depressed toward the second position the motor rotates in a second direction to decrease the power to the torch, and when pressure on the switch is released in either the first or second position the motor stops to maintain the power supplied to the torch at the desired level.
