ABSTRACT:
A stud welding tool has an improved plunge dampener and an improved lifting mechanism assembly. The plunge dampener is mounted in a front cover of the tool for easy assembly and disassembly. A threaded member controls movement of the dampener to adjust the amount of free travel of a stud and chuck assembly during a plunge stroke in a welding cycle. The lifting mechanism is mounted in a housing as an assembly. The housing is located in a bore or recess in the welding tool body and held in place by a main plunge spring in the tool. The housing and lift mechanism is easily installed and removed for replacement or repair.
