For use with a weld gun comprising a weld gun body, a first weld arm member carrying a first weld tip and extending from the body at a first angle, a second weld arm member carrying a second weld tip and extending from the body at the first angle and generally parallel to the first weld arm member to establish a first weld gun axis, an actuator mounted on the body and operative to impart relative movement to the weld arm members to facilitate movement of the weld tips to positions on opposite faces of a work piece, a transformer carried by the body, a first shunt having a first end electrically connected to the transformer and a second end electrically connected to a first edge face of the first weld arm member, and a second shunt having a first end electrically connected to the transformer and a second end electrically connected to a first edge face of the second weld arm member, a method of converting the weld gun from the first weld gun axis to a second different weld gun axis comprises on each weld arm member, providing a second edge face proximate the first edge faces but at an angle with respect to the first edge faces; providing a removable connection of the weld arm members to the body; disconnecting the weld arm members from the body; disconnecting the second ends of the shunts from the first end edge faces of the weld arm members; reconnecting the weld arm members to the body at a second different angle to the body; and connecting the second ends of the shunts to the second edge faces of the weld arm members. |
