XL4015-45 - Bernard Style 400A MIG Welding Gun, 15ft Cable, .045" Wire Ready-to-Weld

Heavy-Duty 400A MIG Performance

The Bernard Style XL4015-45 MIG Gun is engineered for industrial environments where reliability and durability are paramount. Rated at 400 Amps, this air-cooled gun is capable of handling high-deposition welding applications, including structural steel, heavy equipment manufacturing, and general fabrication. The air-cooled design eliminates the need for complex water-cooling systems, reducing maintenance requirements and potential leak points while maintaining a high duty cycle suitable for most shop environments.

This model comes equipped with a 15-foot cable, providing ample reach for welders working on large assemblies or in dynamic shop layouts. The cable is protected by a rugged outer jacket designed to withstand abrasion, hot sparks, and the general wear and tear of a busy industrial floor. The gun is pre-configured for 0.045-inch wire, a standard diameter for medium-to-heavy plate welding, ensuring that you can connect it to your feeder and start welding immediately with minimal setup time.

Maintenance is streamlined thanks to the compatibility with standard Bernard-style consumables. Whether you are replacing contact tips, nozzles, or liners, parts are readily available and easy to swap out, minimizing downtime. The internal liner is designed to feed wire smoothly, reducing bird-nesting and ensuring a stable arc even when the cable is curved. For facility managers and procurement specialists, this gun represents a cost-effective, high-performance solution for upgrading or replacing aging equipment in the fleet.

Key Technical Benefits:

• High Amperage: 400A rating supports spray transfer and flux-cored processes.


• Durability: Reinforced strain reliefs and impact-resistant handle materials.


• Serviceability: Simple design allows for quick liner and consumable changes on the shop floor.
