Tweco 13201125 Nozzle Insulator

The Tweco 13201125 is a replacement nozzle insulator designed for MIG Gun No 2 welding torches. It fits the WS22 series and Classic No. 2, No. 3 and No. 4 models as well as WeldSkill WM 250 and WM 400 guns. Welders who need a direct-fit insulator for these specific torches will find it matches the original equipment.

Compatible torch series and model limits

This insulator works only with the listed Tweco torch series and WeldSkill models. It does not fit other manufacturers' guns or Tweco series not named in the compatibility list. Buyers who need an insulator for a different torch model or a non-Tweco brand cannot use this part.

Pack quantity and typical workshop coverage

The package contains five insulators, giving a small stock for routine tip changes on compatible guns. A busy shop running multiple WS22 or Classic torches may use the pack quickly during high-volume production. Operations that standardise on other torch platforms will need a different insulator altogether.
