Taurus XP8 MIG nozzles are precision engineered and have a thicker wall thickness resulting in superior performance and longevity. The nozzle, also known as a shroud, is used to keep the gas at the weld puddle. When the nozzle spatter builds up or if the nozzle becomes damaged due to miss use, wear and tear or overheating, it can cause the shielding process to be uncontrolled which may result in poor welding, lack of penetration and increased spatter. Build-up of spatter between the contact tip and the nozzle can result in shorting. The nozzle cleaning process can be facilitated by using silicon anti spatter spray which makes removal of the spatter easier. The nozzle can also be removed from the MIG torch and a wire brush used to clean off the spatter build-up. Sold in packaging of 5 units and the price is for 5 units.
