Self-Contained Hot Air Welders with Quick Change Nozzles

These self-contained hot air welders deliver powerful, portable welding performance without the need for an external blower or compressor. Designed for both field repairs and in-shop fabrication, these compact welders feature an integrated air supply, quiet operation below 70 dB, and a built-in LED work light for improved visibility. Both models include a quick-change nozzle adapter that allows compatible welding tips to be swapped without waiting for the tool to cool, helping maximize productivity. A 270° rotating air hose with kink protection, LCD display, stepless controls, and integrated air flow monitoring with automatic heating element protection provide reliable, precise performance across applications including plastic fabrication, pipeline construction, roofing, automotive repair, ventilation systems, tanks, reservoirs, and landfill technology. Complete your hot air welding system with high-quality accessories designed to maximize performance, precision, and versatility. From quick-change adapters and free-hand welding tips to high-speed, tacking, triangular, cap strip, and fluoropolymer-specific welding tips, these professional-grade accessories help you tackle a wide range of plastic fabrication and repair applications. Note: Nozzles with a listed diameter are designed for use with a welding rod of the same diameter.
