Dual Taper Technology

We’ve added a second taper at the rear of our TOUGH LOCK® retaining heads feature a second taper at the rear, so there is one taper for the contact tip connection and a second for the neck.

Dual Taper Technology

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

Dual taper technology:

  • Locks your MIG gun from contact tip to the neck
  • Keeps your consumables running cooler
  • Improves electrical conductivity
  • Decreases your downtime
