12401216 - Tweco 24 Series Heavy Duty Brass MIG Nozzle, 5/8 Inch Bore (Pack of 2)

Upgrade Your Torch with Tweco Heavy Duty Brass Nozzles

When you are pushing high amps and laying down serious beads, your MIG gun's nozzle takes a beating. The Tweco HD24LB62 Heavy Duty Brass Nozzle is built to take the heat so you can keep welding. Designed as a direct upgrade for standard nozzles on Tweco #4 and #5 MIG guns, this nozzle features a robust brass construction that resists spatter adhesion and holds its shape even under intense thermal stress. If you are tired of nozzles that deform or melt too quickly, switching to this heavy-duty brass option is a smart move for your toolkit.

The 5/8-inch bore size is the "goldilocks" of MIG nozzles—large enough to provide excellent shielding gas coverage for a clean, porosity-free weld, yet compact enough to get into tighter joints without snagging. Whether you are welding structural steel, heavy equipment, or general fabrication projects, this nozzle delivers the gas flow consistency you need. The brass material also acts as a heat sink, pulling thermal energy away from the front end of your gun to protect the insulator and contact tip.

One of the best features of this 24 Series nozzle is its adjustability. Because it slips onto the insulator rather than threading on, you can easily slide it back and forth to customize your tip recess. Need a deep recess for high-voltage spray transfer? Slide it out. Need to see the puddle better for short-circuit root passes? Slide it back. This pack contains two nozzles, giving you a backup right when you need it. Keep your arc smooth and your welds clean with genuine Tweco quality.

Why Choose This Nozzle?

• Durability: Heavy-duty brass outlasts standard copper in many high-heat applications.
• Versatility: Adjustable slip-on fit lets you control your stick-out.
• Performance: 5/8" bore ensures reliable gas shielding for quality welds.
