OVERVIEW

Legendary Comfort and Performance

If you spend your day under the hood, you know that the gun in your hand makes all the difference. The Tweco Spray Master MS450 is built for welders who need a torch that can take a beating and keep on welding. Known in the industry as a workhorse, the Spray Master combines a rugged design with an ergonomic handle that fits naturally in your grip, reducing hand fatigue and wrist strain during those long, continuous welds.

This model (10401060) comes ready to rock with a Miller-style back end, so you can plug it directly into your blue machine and get to work. It features a 10-foot cable, which is perfect for bench work or production cells where you need consistent wire feeding without the friction issues of longer cables. Set up for 1/16-inch wire, it's a beast for laying down heavy beads and running hot spray transfer on thick plate.

One of the best things about the Spray Master is how cool it runs. The air-cooled design is incredibly efficient, keeping the handle temperature down even when you are pushing 450 amps. Plus, changing consumables is a breeze. Whether you are swapping out a contact tip or cleaning the nozzle, everything is designed to be quick and easy so you can keep your arc on time high. Stop fighting with flimsy torches and upgrade to the reliability of a Tweco.

Why Welders Choose the Spray Master:

  • Stay Cool: Superior heat dissipation keeps the handle comfortable.
  • Tough Build: Impact-resistant materials survive drops and shop abuse.
  • Perfect Fit: The curved handle design reduces operator fatigue.
  • Easy Fixes: Simple field repairability means less downtime.
