Bossweld long Back Cap

Bossweld Long Back Cap, 9/20 Series fits 9 and 20 series TIG torches. It is the long version, for use with a full-length tungsten electrode. It is supplied in a pack of 2.

The back cap screws onto the rear of the torch head. It seals the head and clamps the tungsten and collet in place, and its length sets how much tungsten you can fit: a long cap takes a full-length electrode, while a short cap suits restricted access.

Key specifications

Choosing the right option

Match the back cap to your torch series, then choose the length for the job: long for full-length tungsten, medium for general use, and short for tight access. Check the back cap O-ring when you replace the cap, because a worn O-ring lets gas leak.
