OVERVIEW

Industrial Grade 350A MIG Welding Gun

The Tweco Spray Master MS350 is a cornerstone of industrial MIG welding, designed to deliver consistent performance in high-demand environments. This specific configuration, identified by SKU 1036-1642, is engineered for heavy-duty fabrication tasks requiring 350 Amps of power. It comes pre-assembled with a Miller-style back-end connection, ensuring immediate compatibility with a wide range of Miller power sources and wire feeders. The gun is rated for an 80% duty cycle at 350 Amps when using mixed gases, making it a robust choice for continuous welding operations.

One of the defining technical characteristics of this model is its 25-foot (7.6-meter) cable assembly. This extended length allows operators to work on large weldments, such as structural steel beams, trailers, and heavy machinery, without the constant need to reposition the welding machine. The cable itself is constructed with high-grade copper stranding and a durable outer jacket that resists cuts, abrasion, and radiant heat, ensuring longevity even in harsh shop floor conditions.

The MS350 utilizes Tweco's industry-standard consumables, including 11 Series contact tips, 52/54 Series gas diffusers, and 22/24 Series nozzles. This specific unit is set up out of the box for 1/16-inch (1.6mm) wire, typically used for heavy-deposition flux-cored or solid wire applications. The conductor tube is metal-jacketed, providing superior impact resistance compared to plastic-molded alternatives, and the simplified design allows for rapid field maintenance. For procurement specialists and facility managers, the Tweco Spray Master represents a balance of proven reliability, widespread consumable availability, and rugged construction.

FAQ

This gun features a Miller-style back-end connection, making it compatible with most Miller wire feeders and power sources that accept a standard Miller MIG gun plug.

The Tweco Spray Master MS350 is rated at 350 Amps at 80% duty cycle when using mixed gases.

Yes, while this unit comes set up for 1/16" (1.6mm) wire, you can change the contact tip and liner to accommodate other wire sizes ranging from .035" to 5/64".

It uses standard Tweco consumables: 11 Series contact tips, 52 or 54 Series gas diffusers, and 22 or 24 Series nozzles.

Yes, the cable assembly features a rugged, abrasion-resistant outer jacket designed specifically to withstand the wear and tear of industrial shop floors.

While it can weld aluminum with the correct nylon liner and aluminum-specific tips, a 25-foot push gun is generally not recommended for soft aluminum wire due to feeding issues. A push-pull gun or spool gun is better for aluminum at this length.

The liner is replaced from the back end of the gun. Simply disconnect the gun from the machine, remove the back-end nut, pull out the old liner, and slide the new one in, trimming it to the correct length.
