GMAW gun liner system allows leeway if liner is cut too short

Tregaskiss will display its new QUICK LOAD™ Liner AutoLength™ system at FABTECH Intl. The system is designed to minimize the problems that can occur when a GMAW gun liner is cut too short, including poor wire feeding, burnbacks, and premature contact tip failure. It can be used with both semiautomatic and robotic GMAW guns.

Housed inside the power pin, a spring-loaded module applies constant pressure on the liner, keeping it seated properly in the retaining head (or diffuser). The new system allows for up to 1 in. forgiveness if the liner is cut too short, and it accommodates liner movement during welding.

After the pin has been installed at the rear of the gun, the liner can be installed from the front of the gun in less than half the time and effort to replace a conventional liner, according to the manufacturer.
