ABSTRACT:
A welding gun for wire spring relays has jaws designed to clamp the wire contact arm with the end of the wire on which the contact is to be welded projecting a predetermined amount through the jaws. Mechanism on the gun brings the contact against the clamped wire (to which it is to be welded) with a predetermined spring pressure, the mechanism increases the pressure between contact and wire by a consistent amount before initiating the welding operation.
