Welder System Produces Precision Mold and Die Repairs

Gesswein & Company’s PUK U5 welder offers precision mold and die repairs. Utilizing micro TIG technology, the welder produces small, consistent spot welds that penetrate the mold surface, and it does not require pre-welding heat treatment. Operators can repair parting lines, mold seams and three-point corners and edges, as well as fill in pits and deep scratches on the mold surface. Welding into slots, corners and ribs is possible using different electrodes, and slides, ejectors and core pins can also be repaired. It can be used on all common tool steels, stainless steels, aluminum and copper. All heat is concentrated at the weld spot, eliminating distortion and metal stress caused by overheating, enabling the mold to withstand pressures during the molding process. The system comes complete with microscope, LED light, electrode handpiece, set of 0.6 mm and 0.8 mm electrodes, electrode sharpener, ground cables, argon gas regulator, tack resistance welder and foot pedal, and it comes with a one-year manufacturer's warranty.
