75001738 - American Weldquip 400A MIG Gun Nozzle Insulator

Keep Your Torch Running Smoothly

Don't let a cracked or worn insulator ruin your weld or damage your equipment. The American Weldquip 75001738 Nozzle Insulator is the exact replacement part you need for your 400A Weldquip MIG gun. Over time, the intense heat and spatter from welding can degrade your gun's insulator, leading to brittleness or cracks. If the insulator fails, your nozzle can become electrically live, causing it to short out if it touches your workpiece. This not only creates ugly arc marks but can also damage your contact tip, diffuser, or even the welder itself.

Built for High Heat

Designed to handle the demands of 400-amp welding, this OEM insulator is made from durable, high-temperature material that resists melting and breaking. It installs easily, restoring your gun to its original factory performance. Whether you are welding thick plate or running long beads in a production line, trusting genuine American Weldquip parts ensures your gear lasts longer and performs better. Keep a spare in your toolbox to minimize downtime and keep your arcs smooth and consistent.

Why Choose OEM?

Using genuine American Weldquip parts means you never have to worry about fitment issues. Aftermarket insulators often vary slightly in size or material quality, which can lead to loose nozzles or premature failure. This part (75001738) is designed to snap or screw into place perfectly, ensuring your gas flow remains laminar and your nozzle stays isolated.
