Direct shielding gas towards welds and protect contact tips from molten metal.
Flush Nozzle—Flush nozzles let your wire stick out 1/4”-1/2” from the contact tip, so the tip is close to your workpiece. These nozzles are good for welding thin materials under low voltages, decreasing the risk of burning through your workpiece.
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.
