Welding with nitrogen gas creates the strongest welds possible because it eliminates oxidation of the plastic during the welding process. Think of it like TIG welding for plastic, there’s no oxidation, no burning, and no weld contamination. The 6049-C Nitro Fuzer Lite Plastic Welding System combines a simplified nitrogen welder with a traditional airless plastic welder. By combining these welders into one package, it allows you to economically make nitrogen welds to virtually any automotive plastic. The 6049 features precision flow control so the user can match the flow and temperature to substrate types and thicknesses. The flow and temperature can be reduced to a very low point in order to weld thin, fragile substrates, something competitive units may not be able to do.The integrated airless welder is ideal for smoothing out welds, repairing thermoset polyurethane, and adding reinforcing mesh to welded thermoplastic parts.
