Triangle Speed Welding Nozzle Set — 4-piece titanium alloy nozzles for plastic sheet welding Key benefits Precise welding: Four nozzle shapes let you control heat distribution and air flow for clean, accurate seams on plastic sheets. Faster work: Speed nozzles (5 mm round and 7.5 mm triangular) concentrate hot air to increase welding speed while maintaining consistent results. Durable and heat-resistant: Made from titanium alloy to resist high temperatures and provide longer service life than standard nozzles. Simple and flexible: No complicated setup or extra tools — attach the desired nozzle to your hot air blower head heat torch and start welding. What’s included and specifications 1 × 5 mm standard nozzle — general-purpose welding and finishing 1 × 5 mm round speed nozzle — focused, faster welds on narrow seams 1 × 7.5 mm triangular speed nozzle — wider, angled heat pattern ideal for speed welding along edges 1 × tacking nozzle — precision tack welding to hold pieces in place before final seams Material: titanium alloy Designed specifically for plastic sheet welding How it solves common problems Uneven welds or overheating: Different nozzle profiles let you match the heat pattern to the workpiece, reducing burn-through and improving seam uniformity. Slow throughput: Speed nozzles concentrate hot air for faster welding without sacrificing control. Frequent nozzle replacements: Titanium alloy construction improves wear resistance and stability at high temperatures, reducing downtime. Typical applications Repairing PVC or polyethylene tarpaulins, pond liners, and roofing membranes Welding seams and patching inflatable boats, air mattresses, and outdoor gear Joining or patching plastic sheets used in greenhouses, construction barriers, and industrial cladding Usage tips Select the nozzle shape that matches your seam width and required heat pattern. Securely attach the nozzle to your hot air blower head heat torch before powering on. Start with lower temperature and speed settings, then adjust as needed for consistent fusion. Compatibility note Designed for use with hot air blower head heat torch units; ensure your torch accepts standard interchangeable nozzles.
