A modular welding gun includes a frame and an upper and lower yoke both interconnected with the frame. One of the yokes is movable with respect to the frame. An upper weld arm has one end removably interconnected with the upper yoke and the other end designed to support an electrode. A lower weld arm has one end removably interconnected with the lower yoke and the other end designed to support an electrode. An actuator is operable to move the movable yoke between a welding position and a rest position.
