OVERVIEW

Keep Your Tweco Gun Running Smoothly

If you're burning wire with a Tweco #3 or #4 gun, you know that a clogged or beaten-up nozzle can ruin your gas coverage and lead to porosity. This 2-pack of Tweco-style nozzles is the perfect refill for your kit. These are the 1/2-inch bore version (often cross-referenced as 24A-50 or similar), which is great when you need to get into a tighter spot or just prefer a slightly more focused gas cone than the big 5/8" nozzles.

Built from heavy-duty copper, these nozzles can take the heat of 300 to 400 amp welding. They resist spatter buildup better than cheaper alternatives, meaning you spend less time banging your gun or reaching for the nozzle dip and more time laying beads. They slip right over your standard insulator, holding firm but allowing you to slide them back and forth to get your contact tip stick-out exactly where you like it.

Whether you are working on structural steel, heavy equipment repairs, or general shop fabrication, having fresh nozzles is key to a clean weld. Don't let a battered nozzle compromise your shield gas. Grab this pack of two and keep your front end fresh.

Why Welders Choose This Nozzle

  • Perfect Fit: Slides right onto your standard Tweco 300A or 400A whip.
  • Tough Build: Thick copper walls handle the heat and abuse of daily shop life.
  • Versatile Size: The 1/2" opening is a great all-rounder for most wire sizes and joints.
  • Value Pack: Comes with two nozzles so you always have a backup.

FAQ

This nozzle is designed to fit Tweco No. 3 (300 amp) and No. 4 (400 amp) MIG guns, as well as compatible guns like the Lincoln Magnum 300 and 400 series.

The bore size is 1/2 inch (0.500"), which is a standard size for general purpose welding and offers good access to joints.

Yes, this is a slip-on nozzle that requires a compatible insulator (typically part number 34A or 34CT) on the gas diffuser to hold it in place.

Yes, when used with the correct slip-on insulator, you can slide the nozzle up or down to adjust your contact tip recess or stick-out.

This product contains a package of 2 nozzles.

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

You can use nozzle dip (anti-spatter gel) to prevent sticking, and clean it periodically with a pair of welpers or a nozzle reamer tool.

While you can use it, flux-cored welding (FCAW-S) often doesn't require a nozzle, or uses a thread protector. However, for gas-shielded flux core (Dual Shield), this nozzle is required to direct the gas.
