Millermatic 355 MIG Welder

Allowing operators to weld a variety of materials, the Millermatic 355 MIG welder is an easy-to-use power source designed for fabricators and manufacturers. With the ability to work in many environments, it can operate on single-phase or three-phase AC power. The machine provides MIG and pulsed MIG capabilities for mild steel, aluminum, and stainless steel in thicknesses from 22 gauge to 0.5 in. (12.7 mm).

With high amperage output and a long duty cycle, operators can make longer welds without stopping. The pulsed MIG capabilities allow operators to reduce heat input for better results on stainless steel, less risk of distortion or burn-through on thin metals, and reduced spatter on all materials. An industrial, four-drive-roll, wire-feed system ensures consistent delivery of all wire types and diameters at all speeds. The Millermatic 355 is compatible with push-pull guns.

Auto-Set Elite makes it quick and simple to select the right parameters to produce high-quality welds. An LCD user interface clearly shows weld settings and displays an electronic parameter chart, making settings easy to access, fine-tune, and save. In addition, Program Mode lets welders save up to four frequently used weld processes in the machine. Trigger Program Select lets operators select any saved process at the weld joint by pulling the MIG gun trigger, so there’s no need to walk back to the power source.
