1. A cap extractor for a welding gun comprising:
a housing;
a pair of springs; and
first and second arms arranged between the springs, each of the first and second arms having teeth configured to engage a welding cap, the first and second arms configured to move relative to the housing by deflecting the springs, the first and second arms are mounted to spaced apart disks, wherein an actuator is pivotally attached to the housing, the actuator operatively connected to the first arm to rotate the first and second arms along with the disks, the actuator configured to articulate relative to the housing during rotation of the first arm in the housing.
