OVERVIEW

Reliable Performance for Your MIG Gun

Keep your welds clean and your arc stable with these high-quality replacement MIG nozzles. Designed as a direct replacement for the standard Tweco 21-50 nozzle, this 2-pack ensures you always have a spare on hand when you need it most. The 1/2-inch bore is the "gold standard" for most MIG welding projects, offering a perfect balance of gas coverage and accessibility into tighter joints.

Whether you are running a classic Tweco #1 or #2 gun, or using a welder equipped with a Lincoln Magnum 100L torch, these nozzles slide on easily and stay put. The precision-machined copper construction withstands the heat of the arc and resists spatter buildup, while the smooth interior finish promotes laminar gas flow to protect your weld pool from porosity. Don't let a clogged or damaged nozzle ruin your bead—swap it out in seconds with this convenient twin pack.

Key Benefits

  • Universal Fit: Works with the most common MIG guns in the industry.
  • Optimal Gas Coverage: 1/2" opening provides excellent shielding for standard wire sizes.
  • Easy Maintenance: Slip-on fitment makes cleaning and replacement a breeze.
  • Great Value: Includes two nozzles to keep you welding longer.

This package contains two (2) nozzles.

It is made of a durable copper alloy designed to withstand high heat and resist spatter adhesion.

While you can physically leave it on, flux-cored welding (FCAW-S) typically requires a gasless nozzle (or no nozzle) to prevent tip overheating and improve visibility. This nozzle is designed for gas-shielded MIG welding.

This is a Firepower branded product, which is a brand of ESAB. It is a high-quality aftermarket replacement for Tweco style parts.
