When it comes to high-amperage air-cooled MIG welding, the Tweco Spray Master series stands alone as the preferred choice for professional fabricators. This MS450 model is rated for 450 amps at an 80% duty cycle, making it capable of handling spray transfer modes and flux-cored applications with ease. Designed for durability and ease of maintenance, it eliminates the complexity of water-cooled systems while providing the thermal capacity needed for thick plate welding.
Stop struggling with short cables. This model comes with a 25-foot (7.6 meter) cable assembly, offering exceptional reach for working on trailers, large vessels, or structural beams. The cable is engineered to maintain consistent wire feeding even at this extended length, thanks to Tweco's low-friction liners and high-quality conduit design. The backend is fitted with a Miller-style connector, ensuring instant compatibility with your existing Miller wire feeders and power sources.
Out of the box, this gun is set up to run 1/16-inch wire, a common size for heavy fabrication where high deposition rates are critical. The contact tips and liners are matched to this diameter to ensure smooth arc starts and stable feeding. However, the gun is fully adaptable; by simply changing the liner and contact tip, it can easily run other wire sizes ranging from .035" to 5/64", making it a versatile tool for any shop.
The Spray Master is designed with the welder in mind. The split-handle case allows for easy access to the trigger and cable connections for field repairs. The patented conductor tube can be rotated to suit the operator's preference, and the heavy-duty contact tips provide excellent electrical conductivity and wear resistance. If you need a MIG gun that works as hard as you do, the Tweco Spray Master MS450 is the reliable solution you've been looking for.
