Welding gun having non-threading contact tip

摘要

A welding gun adapted to secure a contact tip within the welding gun without threading the contact tip and without the use of tools. The contact tip may be adapted to abut a surface of a first member disposed within the welding gun. The surface may be a surface of a gas diffuser. The surface may be adapted to abut the contact tip. The contact tip also may be adapted for abutment with a second member to urge the contact tip toward the first member. The second member may be a portion of a nozzle adapted to abut the contact tip to urge the contact tip toward the surface of the first member. A method of assembling a welding gun also is provided. The method may include disposing a contact tip between a first and a second member and capturing the contact tip between the first and second members.
