Upgraded Retaining Heads for MIG Welding Guns

Tregaskiss has upgraded the design of its TOUGH LOCK retaining heads so that they now feature the company’s Dual Taper technology — a second rear taper between the gooseneck and the contact tip. This design improves electrical conductivity and heat dissipation to provide consistent welding performance and extend the life of the TOUGH LOCK consumables. The upgrade also complements the existing taper design between the retaining head and contact tip, which helps keep the tip secure, centered, and cool. Tips are machined with tight tolerances and feature a dual-lead thread design that allows the tips to be rotated 180 degrees to create a new wear position and extend tip life. The retaining heads are useable on both semi-automatic and robotic MIG (metal inert gas) guns. (
