907747001 - Miller Deltaweld 350 MIG Power Source, 208-460V, 14-Pin & ArcConnect

Simplify Your Setup, Amplify Your Arc

Welding should be about laying down perfect beads, not fighting with complicated machine settings. The Miller Deltaweld® 350 is designed with the operator in mind, featuring the innovative EZ-Set technology. With EZ-Set, you simply select your material thickness on the machine or compatible feeder, and the Deltaweld automatically sets the optimal parameters for you. This removes the guesswork and reduces the time spent dialing in the machine, allowing welders of all skill levels to get into production faster and with more confidence.

This power source is a beast when it comes to performance. Rated at 350 amps, it handles solid wire MIG and Flux-Cored applications with ease. Whether you are welding thick plate for heavy equipment or fabricating structural components, the arc stability is exceptional. If you are used to the older Deltaweld 352, you will find this machine familiar yet significantly improved. It’s lighter, more energy-efficient, and quieter thanks to the Fan-On-Demand™ system that only kicks on when the machine actually needs cooling. No more constant fan noise droning on in the background while you work.

Flexibility is a major plus with the Deltaweld 350. Do you have a favorite older Miller feeder with a 14-pin cord? Plug it right in—it works perfectly. Want to upgrade to the latest tech? The ArcConnect™ port lets you hook up a new Intellx™ feeder. If you go with the Intellx™ Pro feeder, you even get access to Pulsed MIG welding. Pulse welding gives you a cleaner weld with less spatter and better control, especially when welding out of position. It effectively makes a good welder great and a great welder unstoppable.

The machine is built tough for the shop floor. The metal case is durable, and the internal design keeps the guts of the machine clean from the grinding dust that kills other welders. It’s a complete package of power, reliability, and ease of use that lets you focus on what matters: the weld.
