OVERVIEW

Reliable Nozzles for Your WeldSkill Gun

Keep your MIG welding running smoothly with this 2-pack of Tweco WeldSkill WS22-37SS nozzles. If you are running a Tweco WeldSkill 140, 180, or 220 machine, or an older Mini-MIG setup, these are the genuine replacement nozzles you need. The nozzle is the most abused part of your MIG gun, constantly exposed to spatter, heat, and accidental bumps. Having a fresh 2-pack in your toolbox means you won't be stuck trying to clean out a fused-up nozzle in the middle of a project.

Why choose the 3/8" Bore?
This specific nozzle features a 3/8-inch opening (bore). This is slightly smaller than the standard 1/2-inch nozzles found on heavier industrial guns. The smaller profile is perfect for the lower amperage ranges typically used with WeldSkill machines. It allows you to see the puddle better and get the gun nozzle into tighter corners or narrow V-grooves that a bulky nozzle would block. It concentrates the shielding gas right where you need it, helping you lay down clean, porosity-free welds on sheet metal and light structural steel.

Easy Slip-On Installation
Forget about cross-threading or stuck threads. These nozzles feature Tweco's classic slip-on design. They slide firmly over the insulator, held in place by a friction ring. When it's time to clean out spatter or change your contact tip, just twist and pull—no pliers needed (usually). This design speeds up your consumable changes so you can get back to burning wire. Built from durable copper, they resist spatter adhesion and handle the heat of day-to-day fabrication work.

FAQ

It fits Tweco WeldSkill 140, 180, and 220 MIG guns, as well as Tweco Mini-MIG and standard Tweco #1 and #2 guns set up for slip-on nozzles.

The bore size is 3/8 inch (0.375" or 9.5 mm).

This is a slip-on nozzle. It uses a friction fit rather than threads.

This package contains 2 nozzles.

The Tweco/ESAB part number is 1220-1345, often referred to as WS22-37SS.

A 3/8 inch nozzle is better for lower amperage welding and provides better access to tight corners and joints compared to larger nozzles.

While you can physically use it, flux-cored welding (FCAW-S) typically uses a gasless nozzle (or no nozzle) to prevent spatter buildup. This nozzle is designed for MIG (GMAW) with shielding gas.

It is made of a copper alloy designed for heat dissipation and durability.
