Urethane Supply Company’s new 6056 Nitrogen Welding System is the most complete and technologically advanced plastic welding repair system available in one package. It uses a hot air welder with nitrogen as a shielding gas to prevent oxygen in the air from contaminating the weld. This creates the strongest, fastest repairs possible. It’s easy to repair tears, broken tabs, and mounting holes in polypropylene and TPO bumpers with the included welding ribbons. It can repair slots, holes and flanges that are impossible to do with any other method. The system is fully assembled and includes all accessories. The kit comes with an airless plastic welder, holsters for the hot elements, a toolbox and 11 types of plastic welding rods and ribbons, plus two instructional DVDs.
