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 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
