TREGASKISS™ Common Consumable Platform

Praxair Tregaskiss Common Consumable Platform

TOUGH and FLEXIBLE

Tregaskiss™ has designed its long-lasting consumables for maximum flexibility and compatibility between consumable parts and across various gun models.

Cross Compatibility

In many cases, the same nozzles, TOUGH LOCK™ contact tips and QUICK LOAD™ liners can be used with Tregaskiss semi-automatic, automatic, and robotic MIG guns. The TOUGH LOCK Consumable System can also be extended to competitive brands of MIG guns with the TOUGH LOCK Conversion Series. Less consumable inventory is needed to maximize flexibility and productivity across a variety of MIG welding applications.

Better for Praxair Customers

As part of Praxair’s StarSolver® Productivity Enhancement Program, the Tregaskiss Common Consumable Platform is the cost-effective choice for your ProStar™ robotic welding system. Contact your Praxair Productivity Specialist for details.
