ABSTRACT:
A welding gun that prevents rotation of the electrode, including a cylinder and a reciprocating piston assembly having a pair of pistons. In addition to the conventional connecting rod, the pistons are interconnected by an anti-rotation rod radially offset from the connecting rod. The anti-rotation rod extends through a partition fixed within the cylinder, thereby preventing the piston assembly from rotating within the cylinder. The welding gun also includes an internal proximity switch for detecting when the piston assembly is fully retracted.
