TOUGH LOCK™ Retaining Heads Featuring Dual Taper Technology
We've added a second taper at the rear of our TOUGH LOCK™ Retaining Heads where they connect with the gooseneck. This
Dual Taper Technology:
- Locks your gun from contact tip to the gooseneck
- Makes your consumables run cooler
- Improves electrical conductivity
- Decreases your downtime
Enjoy all of these benefits AT NO EXTRA COST! Simply update
your part numbers to be sure that you get our newest technology
the next time you reorder your TOUGH LOCK Retaining Heads.
TOUGH GUN Semi-Automatic, Automatic and Robotic MIG Guns use the same Tregaskiss™ Common Consumable Platform resulting in less overall inventory.
NOTICE: These Retaining Heads are standard
on all TOUGH GUN™ Air-Cooled Semi-Automatic,
Automatic, and Robotic MIG Guns (excluding flex
neck models) as of November 1, 2009.
