$5,889.51Price
Quantity

The Miller Millermatic 355 is a pulsed MIG welder for MIG, flux-cored and pulsed MIG welding in manufacturing, construction and fabrication. It connects to North American single- or three-phase power at 208, 240, 460 or 575 V, is rated 310 A at 29.5 V with a 60% duty cycle, and welds aluminum, stainless and mild steel up to 1/2 in. thick.

Output covers 20-400 A with 90 VDC maximum open-circuit voltage and 50-800 IPM (1.3-20 m/min) wire feed speed, and the input voltage selection switch sits in the wire drive compartment, with an error shown if the wrong input is selected. The 7-inch color LCD brings Auto-Set Elite, an electronic parameter chart and program mode, and Trigger Program Select changes programs with a tap of the gun trigger. Locks and Limits keep parameters within the welding procedure specification (WPS), and a USB port updates software and transfers programs.

This base power source comes with a 9 ft (2.7 m) industrial power cord, a 300-amp, 15 ft (4.5 m) Bernard BTB MIG gun fitted with AccuLock S consumables, a work cable and clamp with a 50 mm Dinse-style connector, a flow gauge regulator and gas hose, reversible drive rolls, extra contact tips and a material thickness gauge. It feeds solid steel, stainless, flux-cored, metal-core, aluminum and silicon bronze wire from 12 in. spools, EZ-Latch running gear is optional, and the welder reaches full output on generators of 19,000 watts or more.
