Built for the Toughest Jobs

When the sparks are flying and the heat is on, you need a MIG gun that won't let you down. The Tregaskiss 400A "Tough Gun" (Model MXL4015-116) is the ultimate tool for professional welders who demand reliability and durability. Known throughout the industry as one of the most rugged MIG guns available, this torch is designed to withstand drops, drags, and the general abuse of a busy shop floor. Whether you are welding heavy equipment, repairing railcars, or fabricating structural beams, this 400-amp powerhouse delivers consistent results every time you pull the trigger.

Direct Fit for Miller Welders

Forget about adapters and complicated setups. This gun features a direct-connect Miller back end, making it the perfect upgrade or replacement for your existing Miller wire feeder setup. The 15-foot lead gives you plenty of room to work, allowing you to reach around large assemblies without stretching the cable. It comes ready to run 1/16" wire, a common size for heavy-plate welding, so you can get straight to work on your thickest materials. The secure connection ensures optimal conductivity and gas flow, resulting in a stable arc and high-quality welds.

Comfort Meets Control

Welding at 400 amps generates significant heat, but the Tregaskiss design keeps the handle cool and comfortable. The ergonomic grip is contoured to reduce fatigue, allowing you to maintain precision control over the puddle for longer periods. The neck is angled for optimal visibility and access to tight joints. Additionally, the gun utilizes Tregaskiss's high-performance consumables, which are famous for their longevity and ease of replacement. The nozzle and contact tip design prevents spatter buildup and ensures excellent gas coverage, reducing post-weld cleanup.

Key Features for the Pro

This air-cooled MIG gun combines simplicity with high performance. Without the need for a water cooling system, you have fewer hoses to manage and zero risk of coolant leaks. The heavy-duty outer jacket protects the copper power cable from cuts and burns, while the sturdy strain relief prevents cable failure at the connection points. If you are looking for a MIG gun that works as hard as you do, the Tregaskiss 400A with Miller connection is the industry standard for a reason.
