TOUGH LOCK Retaining Heads with Dual Taper Technology


We've added a second taper at the rear of our TOUGH LOCK™ Retaining Heads, so there is one taper for the contact tip connection and a second for the neck (cutaway shown in the image gallery to the right).

Dual Taper Technology creates a more secure seat, preventing the contact tip and retaining head from loosening due to vibration.

This Dual Taper Technology:

  • Keeps your consumables running cooler
  • Improves electrical conductivity
  • Decreases your downtime


TOUGH LOCK Retaining Heads with Dual Taper Technology are standard on the following MIG Guns (excluding flex neck models):
