12301230 - Tweco Style 23H75 Heavy Duty MIG Nozzle, 3/4" Bore (2-Pack)

Heavy-Duty Performance for High-Heat Welding

Upgrade your MIG torch's front end with the 23H75 Heavy Duty Nozzle, specifically built for welders who push their equipment to the limit. When you are running high amperage or engaging in spray transfer welding, standard nozzles can overheat, deform, or accumulate spatter too quickly, leading to downtime and frustration. This heavy-duty variant offers thicker copper walls, acting as a superior heat sink to keep your consumables cooler and lasting longer, even during extended arc-on times.

Superior Gas Coverage
The 3/4-inch (0.750") bore is one of the largest in its class, providing a wide, stable umbrella of shielding gas. This is essential for preventing weld defects like porosity, especially when working on critical structural joints or when welding outdoors where slight drafts might disturb a smaller gas stream. The wider opening also allows for better visibility of the weld puddle and accommodates larger contact tips and wire sizes with ease, making it a favorite for heavy fabrication and structural steel work.

Easy Maintenance and Compatibility
Designed as a direct replacement for Tweco® #3 and #4 style guns, as well as Spray Master 350 and 450 series, these slip-on nozzles make maintenance a breeze. There are no threads to seize up from heat or spatter; simply slide the old nozzle off and push the new one on. The robust copper construction resists spatter buildup, making it easier to clean and ream out between welds. Sold in a convenient pack of 2, this set ensures you always have a spare on hand when it counts, keeping your production line moving and your welds clean.
