  • Small.
TIG Welding Gun - Back Caps
TIG Welding Gun – Back Caps

The back cap applies pressure on the collet. This holds the Tungsten electrode in place.

A new Tungsten electrode is normally about 7″ (175mm) long. As the Tungsten electrode gets shorter, you can change the back cap to a smaller size. A smaller back cap allows the TIG torch to be used where space is restricted. So keep some shorter Tungsten electrodes back for this purpose, rather than using them up completely.

  • Make sure the back cap fits your particular TIG torch before purchasing.
