Pipe Welding-Model 501

Pipe Welding-Model 501

The Model 501 was designed to supply resistance heated filler wire near melting temperatures to weld pool, thereby increasing the energy available to melt the base metal.

The Model 501 is suitable for welding high-quality stainless steel tanks and vessels that are rotated during welding. The addition of hot wire can optimize the corrosion resistance and/or mechanical properties of the weldment and have a beneficial effect on the material performance in service. The hot wire GTAW process produces a very clean weld with a very low incidence of porosity and increases filler deposition rates similar to GMAW.
