ABSTRACT:
Disclosed is a welding gun which includes a mounting block, a motor mounted to the welding block and a barrel through which welding wire is fed by drive rollers turned by the motor. There is a passageway through the welding block which has a valve therein for controlling the flow of a shielding gas through the passageway and through the barrel. A speed control mechanism device is mounted within a removable casing that encloses the block, motor, and speed control mechanism. The speed control includes a knob which is turned by the welder and includes a tactile response element that better enables the welder to determine the correct setting for the desired speed of the wire even though wearing a glove.
