Compatible MIG Nozzle
This MIG nozzle fits Tweco torches and matches the Classic No. 1, Mini-MIG 160 and Spray Master 250 series. It is sold as a pack of two for quick replacement during fabrication or repair work. The component is intended for welders who need a direct-fit consumable for these specific torch models.
Build Integration
The nozzle threads onto compatible Tweco torch bodies without adapters, freeing the operator from sourcing brand-specific spares. It suits workshops that standardise on the listed Tweco series and want a single part number for multiple machines. Buyers using other torch brands or series will need a different nozzle design.
Thermal Behaviour
The copper-alloy construction handles the heat generated by the listed 160-amp and 250-amp torches during normal MIG welding cycles. No active cooling is required beyond the torch's standard gas flow. The part is not rated for continuous duty beyond the amperage range of the compatible torches.
