Sold in convenient 5-packs for cost-effective replacement. The smooth interior surface prevents spatter buildup for consistent performance. Ideal for short-circuit and spray transfer welding applications. Each nozzle is individually inspected for concentricity and dimensional accuracy. Compatible with all shielding gases including argon mixes and CO2.
