OVERVIEW

Heavy-Duty Industrial Performance

The Tregaskiss Style MXL 400A MIG Gun is engineered for high-volume industrial manufacturing and heavy fabrication environments. Designed to meet the rigorous demands of continuous welding operations, this air-cooled torch delivers a robust 400-amp output, making it suitable for welding thick structural steel, heavy equipment, and pressure vessels. The gun comes pre-configured with a liner and contact tip setup for 0.045-inch wire, a standard diameter for high-deposition applications. Its 15-foot cable assembly provides the necessary reach to access large weldments without constantly repositioning the wire feeder, enhancing workflow efficiency in busy shop floors.

Seamless Compatibility and Durability

This model features a Miller-style back-end connection, ensuring direct plug-and-play compatibility with a wide range of Miller wire feeders and integrated power sources. The power pin is precision-machined for optimal conductivity and secure seating, minimizing voltage drop and gas leaks. The "Tough Gun" chassis architecture is built to withstand impact, heat, and abrasion. The outer cable jacket is constructed from high-grade, cut-resistant materials that protect the internal power cable, gas hose, and control leads from shop floor hazards. Heavy-duty strain reliefs at both the handle and the feeder end prevent cable kinking and pull-out, significantly extending the service life of the gun assembly.

Maintenance and Consumables

Maintenance is streamlined with the use of standard Tregaskiss-style consumables. The nozzle, contact tip, and diffuser are designed for quick replacement, reducing downtime during shift changes or maintenance intervals. The gun utilizes a high-performance liner that ensures smooth wire feeding, critical for maintaining a stable arc and preventing burn-back. Whether used in semi-automatic handheld applications or adapted for specific fixturing, this 400A MIG gun offers a reliable solution for fabricators requiring consistent performance and durability. It is an ideal replacement or upgrade for existing Miller-equipped welding stations requiring a rugged, air-cooled torch solution.

FAQ

This gun comes pre-configured with a liner and contact tip for 0.045-inch welding wire.

Yes, this gun features a Miller-style back-end connection, making it compatible with most Miller wire feeders and Millermatic machines that use the standard Miller power pin.

This is an air-cooled MIG gun, rated for 400 amps.

Yes, but you will need to change the contact tip and potentially the liner to match the smaller .035" wire diameter for optimal performance.

The cable length is 15 feet, providing good reach for most fabrication setups.

Yes, this gun uses standard Tregaskiss-style consumables (nozzles, tips, diffusers) which are widely available in the welding industry.

While specific duty cycles can vary by gas type, 400A air-cooled guns are typically rated around 60% duty cycle with CO2 gas.

Yes, the gun assembly includes a standard trigger switch integrated into the handle.
