Urethane Supply Company's Nitrogen Plastic Welding System No. 6056 combines an Airless Plastic Welder No. 5600HT, a Hot Air Welder No. 6053, and a Nitrogen Control Box No. 6053N2 on one welding cart. The technician can simply plug in the unit, connect a nitrogen tank and shop air, and begin working. Nitrogen acts as a shield to prevent the melted plastic from burning and creates stronger, more permanent welds. Using Urethane Supply Company's ribbon repair rods, a technician can repair mounting holes, slots, tabs, and grill bars that no other method can.
