The DM-350 is operated via a simple interface that revolves around a single knob that adjusts the voltage and current (wire speed) and visual buttons. A large LED is used to display settings and weld parameters. The buttons can easly be pushed even while wearing welding gloves.

Constant Penetration Control Function

The DM-350 comes standard equipped with Daihen's Constant Penetration Control Function. Maintain superior weld integrity via uniform penetration throughout the weld!

Semi-Automatic & Robotic Welding

Easily configured for both semi-automatic and robotic use, the DM-350 also fully integrates with our FD, AII and ALMEGA AX Series Arc Welding Robots.

The DM-350 is also be retrofitted onto any other brand robot. Please see our robotic retrofit page for details.
