75001740 - American Weldquip 500A MIG Gun Nozzle Insulator

Keep Your Arc Stable with the American Weldquip 500A Nozzle Insulator

When you are pushing 500 amps, your MIG gun takes a beating. The heat is intense, and the last thing you need is your nozzle shorting out against the workpiece. The American Weldquip 75001740 Nozzle Insulator is the genuine OEM replacement part you need to keep your torch running cool and safe. Designed specifically for American Weldquip's heavy-duty 500A MIG guns, this insulator acts as the critical barrier between your hot, electrically live front-end consumables and the outer nozzle.

Why stick with OEM? Because fitment matters. This insulator is precision-molded to seat perfectly inside your torch head, ensuring that your gas diffuser and contact tip stay centered and isolated. A worn or cracked insulator can cause erratic arcs, poor gas coverage, and even damage to your power source if the nozzle shorts out. The 75001740 is crafted from durable, heat-resistant material that resists charring and crumbling, even under the punishment of high-duty-cycle welding. It helps extend the life of your nozzles and keeps you welding longer without interruption.

Installation is straightforward, making it easy to swap out right on the shop floor or in the field. If you notice your nozzle getting unusually hot or seeing signs of arcing on the nozzle itself, it's time to check your insulator. Don't risk your weld quality or your equipment with generic knock-offs that might melt or slip. Trust the part that was engineered for your gun. Whether you are welding structural steel, heavy equipment, or pipe, this insulator ensures your American Weldquip gun performs exactly how it was designed to.

Features for the Pro Welder:

• High Heat Resistance: Won't melt or deform under 500A loads.
• Perfect Fit: Snaps correctly into place for reliable gas flow.
• Electrical Safety: Stops the nozzle from becoming "live."
• Durability: Tough material resists mechanical shock and spatter buildup.
