Urethane Supply Companys 6056 Nitrogen Welding System is the most complete and technologically advanced plastic welding repair system available in one package. The Nitrogen Welding System includes virtually everything a shop needs to make the highest quality welds to plastic parts. The system includes a 5600HT Airless Plastic Welder and a 6053 Hot Air Welder coupled to a 6053N2 Nitrogen control box, along with a large supply of welding rod and a fully assembled welding cart. Right out of the box, the system is ready to use with minimal set-up. Just connect a nitrogen tank and compressed air supply, then plug it in and begin making top quality nitrogen welds. Nitrogen acts like a shielding gas, preventing oxidation and creating a much stronger weld. Because everything is contained on one cart, searching for the right tools and supplies is simple; it saves time and money!
