Sturdy Material: The welding nozzles are made of titaniumalloy material, providing durability and longlasting performance. Compatibility: Specifically designed for PVC plastic sheets, these welding nozzles are suitable for a variety of welding projects. Various Sizes: The set includes a standard 5 mm nozzle, a 5 mm round speed nozzle, a 5 mm triangular speed nozzle, and a tacking nozzle, offering different options for different welding needs. Precise Dimensions: The standard nozzle has a length of approximately 32 mm or 35 mm, while the speed nozzles have a 5 mm diameter. The triangular speed nozzle measures 5x5x7 mm. Key Benefits: Built to withstand repeated heat exposure, these nozzles enable precise and clean welds on PVC sheets. The range of nozzle types supports different seam patterns and speeds, improving efficiency and reducing material waste. The titaniumalloy construction helps extend nozzle life in demanding welding tasks. Use Scenarios: Sealing and welding PVC sheet panels for signs, displays, banners, or other PVCbased assemblies. Repairing or fabricating PVC tarps, awnings, or covers that require strong, consistent seams. Creating or repairing PVC enclosures, casings, or housings for projects such as tents, boats, or outdoor gear.
