Abstract

A stud welding device ( 1 ) with a stud holder ( 3 ) having a pointed region ( 2 ) for holding a weld stud ( 4 ) and a device ( 5 ) designed as an insulating spacing means with a rim ( 7 ). The pointed region ( 2 ) of the stud holder ( 3 ) always remains behind the rim ( 7 ) of the spacing means, thereby preventing electrical contact between the pointed region ( 2 ) and a component ( 6 ). The stud welding device ( 1 ) is reduced in size because it is formed without a support foot.

Claims (3)

1. A stud welding device comprising:

a hollow tubular stud holder shaped for allowing a weld stud to be pushed therethrough and having a pointed region for holding a weld stud that projects from the stud holder, so that the weld stud can be welded to a component, and a device for preventing an electrical contact between the pointed region of the stud holder, and the component, the device being constructed as an insulating spacing means with a rim, wherein:

the insulating spacing means is arranged substantially annularly around the pointed region of the stud holder and is fixed relative to the stud holder, with the pointed region of the stud holder always remaining behind the rim of the spacing means.
