ABSTRACT:
A welding gun for replacing the movable contacts of wire spring relays is provided with a pair of jaws relatively movable toward each other to clamp the contact material to the relay arm for welding them together. A manual control member is movable to cause the relative movement over a resilient connection which provides the clamping pressure. The manual control member moves past the point in its travel where clamping is achieved stressing the resilient connection to actuate a switch to initiate the welding cycle. The clamping pressure is thus controlled at the time that welding commences.
