12101120 - Tweco 21-62 MIG Gun Nozzle 5/8" Bore (Pack of 2)

Reliable Gas Coverage with Tweco 21-62 Nozzles

Keep your MIG torch running smoothly with this 2-pack of Tweco 21-62 Standard Nozzles. Designed for the widely used Tweco #1 and #2 series MIG guns, these nozzles are a staple in welding shops across the country. The 21-62 features a 5/8-inch bore, which is widely considered the "standard" size for most general welding tasks. It offers a perfect balance between gas flow and accessibility, allowing you to get into standard joints while maintaining a robust shield of gas around the weld pool.

The slip-on friction fit is a major advantage for welders who need to clean spatter or change contact tips frequently. Simply twist and pull to remove the nozzle—no threads to seize up or damage. This design relies on the 32 series insulator to hold the nozzle in place, so ensure your gun is equipped with a good condition insulator for the best fit. The copper construction effectively dissipates heat, preventing the nozzle from overheating during long weld beads.

This pack of two ensures you aren't caught off guard in the middle of a project. When spatter buildup becomes too difficult to remove or the nozzle edge becomes uneven, simply swap it out for a fresh one to maintain optimal weld quality. Compatible with a vast range of aftermarket and OEM guns that follow the Tweco style, the 21-62 is the go-to choice for reliability and performance in MIG welding.
