Deltaweld® 350 MIG/MAG Welding Machine

The Deltaweld 350 is a MIG/MAG welding machine designed for advanced industrial manufacturing. It supports multiple welding processes including Accu-Pulse® (pulsed MIG), High-Deposition MIG (HD-MIG) and RMD®, providing flexibility across a range of materials and material thicknesses. The EZ-Set function simplifies parameter setup based on material thickness. Accu-Pulse® is a pulse process that compensates for variations in operator technique and fit-up, and is suitable for all weld positions. RMD® delivers very low heat input and can replace TIG welding on pipe root applications. HD-MIG offers higher deposition rates and improved bead appearance on thicker materials. The machine comes with a three-year warranty (Miller True Blue Warranty) and is suited for heavy industrial manufacturing, construction, transportation, pressure vessels and pipes, as well as sheet metal fabrication.
