Item Details

  • The best just got better. Tweco Velocity. We listened to welders and they said, -Ëœfewer tools and fewer threads'. The outcome is a design that is simpler, requires no tools, and virtually eliminates problems with threads. Typical MIG consumables have TWO sets of threads and many have THREE - Velocity has reduced this down to ONE set. Also, Velocity's mating threads share a soft material (brass) along with a hard material (stainless steel). The combination of soft threads against hard reduces seizing and cross threading. Heat-treated stainless threads on the gooseneck are virtually indestructible and the brass threads on the replaceable nozzle are softer, so they grip and won't loosen.


  • Fixed Threaded maintains a fixed, consistent flushness relationship between nozzle opening and contact tip
  • Adjustable Slip allows welder to adjust the flushness relationship and provides improved access for cleaning
  • Spot Weld provides a solution for tack and spot welding with MIG
