WIA Nozzle Brass With Insulator – 400 A – BE4491
Product Description
The WIA Brass Nozzle with Insulator 400A (BE4491) is a high-performance MIG welding nozzle designed for heavy-duty welding applications requiring reliable shielding gas coverage and superior heat resistance. Manufactured from durable brass and fitted with a heat-resistant insulator, this nozzle delivers consistent welding performance and extended service life in demanding industrial environments.
Engineered to suit 400 amp MIG welding torches, the BE4491 nozzle ensures smooth gas flow distribution, helping protect the weld pool from contamination while reducing spatter build-up. The integrated insulator improves electrical isolation and heat management, making it ideal for high-amperage fabrication and continuous welding operations.
Perfect for professional welders, fabrication workshops, and manufacturing applications, this genuine WIA consumable maintains stable arc conditions and promotes cleaner, higher-quality weld results.
