OVERVIEW

High-Performance 450A MIG Gun for Industrial Applications

The CM415-3545 is a robust air-cooled MIG welding gun designed for heavy-duty fabrication and manufacturing environments. Engineered to deliver consistent performance, this gun is rated at 450 Amps with 100% duty cycle when using CO2 shielding gas, and 60% duty cycle with mixed gases. This high thermal capacity makes it an excellent choice for continuous welding operations on thick structural steel, heavy equipment, and pressure vessels.

One of the key technical advantages of this model is its hybrid compatibility configuration. The backend is outfitted with a standard Miller-style power pin, allowing for direct plug-and-play connection to a wide range of Miller wire feeders and integrated welding power sources. Conversely, the front end utilizes the industry-standard Tweco-style consumable platform. This design choice ensures that operators can easily source replacement contact tips, gas nozzles, and gas diffusers from virtually any welding supply distributor, minimizing downtime and operational costs.

The 15-foot cable assembly provides ample reach for working around large assemblies without compromising wire feedability. The gun comes pre-configured with a liner suitable for 0.035-inch to 0.045-inch welding wires, covering the most common industrial wire diameters. The ergonomic handle is designed to withstand the rigors of the shop floor while providing a comfortable grip to reduce welder fatigue during extended arc-on time.

FAQ

Yes, this gun is equipped with a Miller-style back end connection, making it compatible with most Miller wire feeders and MIG machines that accept standard Miller gun plugs.

This gun uses standard Tweco-style consumables, specifically the 14 Series contact tips and compatible nozzles and gas diffusers (often referred to as Tweco #4 style).

It is rated for 400 Amps, making it suitable for heavy-duty welding applications using thicker materials.

This is an air-cooled MIG gun, which uses the ambient air and shielding gas flow to dissipate heat.

The gun comes set up for .035" to .045" wire. You can run other sizes by changing the liner and contact tip to match your desired wire diameter.

The cable length is 15 feet, providing good reach for working around large assemblies.

Yes, it comes pre-installed with a steel liner suitable for standard welding wires.

While possible, you would need to replace the steel liner with a polymer (Teflon) liner and use aluminum-specific contact tips to prevent feeding issues.
