OVERVIEW

ESAB Tweco MS315M Spray Master 350 MIG Gun - Miller Style

Upgrade your welding setup with the ESAB Tweco Spray Master 350, a 350-amp air-cooled MIG gun engineered for superior performance and longevity. This model (SKU 10361731 / MS315M) comes equipped with a Miller-style rear plug, ensuring seamless compatibility with most Miller wire feeders and power sources. The 15-foot cable assembly is constructed with high-quality stranded copper, providing excellent conductivity and flexibility while resisting the wear and tear of industrial environments.

Built for the Professional Fabricator

The Spray Master 350 is designed to minimize downtime and maximize productivity. Its 80% duty cycle (using CO2) allows for extended welding periods without overheating. The gun features a heavy-duty conductor tube that can be rotated to suit various welding positions, significantly improving access to difficult joints. The simplified internal design means that field repairs can be performed quickly, often without specialized tools, keeping your production line moving.

Consumable Compatibility & Efficiency

One of the standout features of the Spray Master line is its use of standard Tweco consumables. It comes set up for 0.035" to 0.045" wire and utilizes the popular 11 Series contact tips, 52 Series gas diffusers, and adjustable nozzles. These consumables are engineered for optimal electrical transfer and gas coverage, resulting in cleaner welds and less spatter. The cable liner is easily replaceable, ensuring smooth wire feeding over the life of the gun. Choose the ESAB Tweco Spray Master 350 for a MIG gun that delivers consistent results, shift after shift.
