ABSTRACT:
A welding gun apparatus for resistance welding including a longitudinal guide track provided on a pair of fixed plates. The longitudinal guide track extends in a substantially vertical direction and is engaged with both the lower end portion of a carriage for holding a movable electrode arm having a movable electrode and the upper end portion of a piston rod by pins. An arciform guide track formed in the carriage is engaged with pins secured to the respective fixed plates. The longitudinal guide track and the arciform guide track forces the movable electrode arm to move upwardly in a substantially vertical direction at a first stage and then upwardly and obliquely when a workpiece is fed from, and a new workpiece is fed into, a welding station. The carriage is moved smoothly between the welding station and a retracted station, and a sliding portion is prevented from being worn.
