10101105 - Tweco Velocity Adapter for No. 1 Light Duty MIG Guns

Upgrade Your Light-Duty MIG Gun Performance

The ESAB (Tweco) 10101105 Adapter is a specialized component designed to modernize your welding setup. Specifically engineered for Tweco No. 1 style MIG guns and similar light-duty torches, this adapter serves as the bridge between your existing equipment and the advanced Velocity consumable system. By installing this simple yet robust brass adapter onto your gun's conductor tube, you unlock the ability to use Velocity nozzles and contact tips, which are renowned in the industry for their superior performance and longevity.

Many welders struggle with frequent contact tip burn-back and inconsistent gas coverage when using traditional screw-on tips and slip-on nozzles. The Velocity system addresses these issues with a revolutionary design that integrates the gas diffuser into the nozzle and utilizes a threadless, drop-in contact tip. This adapter makes that technology accessible to users of smaller, light-duty guns often found in automotive shops, hobbyist garages, and light fabrication environments. The result is a cooler-running front end, fewer parts to manage, and significantly less downtime spent changing consumables.

Constructed from high-quality brass, the 10101105 adapter ensures optimal electrical transfer from the cable to the wire, maintaining a stable arc even at lower amperages. Its precision machining guarantees a tight fit on the conductor tube, preventing gas leaks that could lead to porosity in your welds. Whether you are welding mild steel, stainless, or aluminum, upgrading your front-end consumables via this adapter can lead to cleaner welds and a more enjoyable welding experience.

Installation is straightforward and requires no permanent modification to your welding gun. Simply remove the old gas diffuser and nozzle assembly, thread on the Velocity adapter, and you are ready to install Velocity tips and nozzles. This small investment extends the life of your current MIG gun while providing professional-grade performance characteristics usually reserved for heavy-duty industrial torches.
