Abstract
A welding gun includes an actuator and welding tips. The actuator includes a stator coupled to a welding robot and a rotor rotatable relative to the stator about an axis of the actuator. The stator includes an axially extending portion and at least one circumferentially extending arm. The rotor includes an axially extending portion and at least one circumferentially extending arm. The welding tips are coupled to an end of the circumferentially extending arm of the stator and an end of the circumferentially extending arm of the rotor. Lengths of the axially extending portion of the stator and the axially extending portion of the rotor can be determined to any length so long as strength and rigidity are assured.
