MIG Gun Nozzles

Recessed Nozzle

Direct shielding gas towards welds and protect contact tips from molten metal.

Recessed Nozzle—Recessed nozzles are the most common and work well in most welding applications. They let your wire stick out _1/2”-_3/4” from the contact tip, so the tip is away from the high heat of the arc and lasts longer. When your wire sticks out, there is also less of a chance it will melt and fuse to the contact tip.

MIG Gun Gas Diffusers

Conduct electricity to your contact tip and evenly distribute shielding gas for high-quality welds. These diffusers reduce turbulence so the gas stays where you need it, which shields the weld and keeps it strong by preventing oxidation and pitting.
