NT174 - Bernard Style 400A MIG Gun 15ft Miller Plug

Heavy-Duty Industrial MIG Welding Gun

The NT174 is a premium aftermarket replacement MIG gun designed to meet the rigorous demands of industrial welding environments. Modeled after the popular Bernard Q-Series style, this gun is engineered for durability, performance, and ease of maintenance. It features a robust 400-amp rating, making it suitable for high-deposition welding applications using flux-cored or solid wires. The air-cooled design is optimized for efficiency, utilizing high-quality copper components to ensure excellent electrical conductivity and heat dissipation.

One of the key technical advantages of this assembly is its 15-foot cable length, which provides welders with significant mobility around large workpieces without compromising wire feedability. The cable is protected by a rugged, abrasion-resistant jacket that withstands the harsh conditions of shop floors, including exposure to sparks, spatter, and rough handling. The connection interface is a standard Miller-style plug, ensuring seamless integration with a wide range of Miller wire feeders and power sources without the need for adapters.

Maintenance and consumable management are simplified thanks to the gun's compatibility with Bernard Centerfire series consumables. The Centerfire system is renowned for its 'drop-in' contact tip design, which eliminates cross-threading issues and ensures consistent arc starts. The gun comes pre-configured with a standard liner and contact tip, ready for immediate deployment. Whether for structural steel, heavy equipment manufacturing, or general fabrication, the NT174 delivers reliable arc performance and longevity.
