Polyvance's most affordable model is the original airless plastic welder, the Mini-Weld® Model 7, designed to repair virtually any type of automotive plastic. The airless welding procedure is the most versatile, allowing fusible thermoplastics and thermosetting polyurethanes (PUR) to be repaired with a single tool. The Mini-Weld Model 7 also allows you to cast stainless steel mesh into plastic to reinforce repair, such as rebar in concrete. Finally, the Mini-Weld Model 7 comes with FiberFlex® universal solder rods, which adhere to virtually any plastic but are designed to work best on PP/TPO bumpers.
