10361610 - Tweco Spray Master MS350 MIG Gun - 350A, 10ft, 1/16 Wire, Tweco Connection

Legendary Comfort and Performance for the Professional Welder

If you have been welding for any length of time, you know that the gun in your hand can make or break your day. The Tweco Spray Master MS350 is designed with the welder's comfort and productivity in mind. Known affectionately in the industry as the "Spray Master," this 350-amp air-cooled MIG gun is a workhorse that doesn't quit. This 10-foot version is perfect for station work where you don't want to be fighting with coils of extra cable on the floor, giving you precise control and reducing trip hazards.

The first thing you will notice is the ergonomic handle. It is shaped to fit naturally in the hand, reducing grip fatigue during long welds. The trigger action is smooth and responsive, designed to minimize finger strain over thousands of cycles. The "Cablehoz" power cable is another standout feature; it offers excellent flexibility without being flimsy, allowing you to maneuver the gun into difficult positions without fighting the lead. The 60-degree conductor tube angle provides a comfortable wrist position for most flat and horizontal fillet welds.

This gun is set up right out of the box for running 1/16" wire, which means it's ready for the heavy stuff—thick plate, structural beams, and heavy machinery parts. The air-cooled design is efficient enough to keep the handle cool even when you are pushing the duty cycle, thanks to the superior copper stranding and airflow design within the cable. You won't have to worry about a hot handle distracting you from your puddle.

When it comes time to swap out consumables, you are working with the industry standard. The Tweco 11 Series tips and slip-on nozzles are easy to change and readily available in almost any shop. The nozzle design stays tight but comes off easily for cleaning spatter. If you ever need to change the liner, the process is straightforward, ensuring you can get back to burning wire quickly. Whether you are spraying metal or running short circuit, the MS350 delivers a consistent, stable arc that helps you lay down high-quality beads shift after shift.
