Easy to use machine to increase efficiency and productivity for manufacturing and fabrication users. 7" Color LCD screen featuring Auto-Set™ Elite, Electronic Parameter chart, and Trigger Program Select. This all-in-one welder connects to any North American input power. Welds up to 1/2” aluminum, stainless and mild steel.

Features

  • EZ-Latch™ running gear: Operators no longer need to use lift truck to load machine and running gear into the truck. Latches secure machine to running gear. Simply loosen the latch retaining knob and rotate latches to disengage machine from running gear for easy portability.
  • Bernard BTB Gun 300 A MIG gun with AccuLock™ S consumables: AccuLock liner loads from the front and locks at the front and back to insure proper alignment for flawless wire feed path. New rubber overmold and ball -and-socket handle design improves grip and reduces welder fatigue. New Industrial Bernard AccuLock™ S contact tips provide superior Spray and Pulsed MIG arc performance.
  • Trigger Program Select: Increases productivity by eliminating the need to go back to the machine to change weld settings. Simply tap gun trigger to select the program.
  • Easy-to-understand interface: 7-inch color LCD display ensures proper machine setup and parameter selection, reducing setup time and increasing weld time
  • Generator Compatible: The Millermatic 355 will be able to operate and provide full output when powered by generators with 19000 Watt (19K) output or higher. Limited output will occur when used with smaller generators.
  • Versatility: Capabilities include MIG, pulsed MIG and flux-cored welding.
  • Pulsed MIG welding delivers higher quality: Lower heat input for less distortion on thin materials, less spatter minimizes post weld grinding and rework allowing more welding time. Perform welding applications that couldn’t be done in the past.
  • Portability - Machine only weighs 99 lb: Weight is reduced by more than 40 percent compared to the Millermatic 350P.
  • Locks and Limits: Provides control of the weld parameter ranges minimizing deviations from the welding procedure specifications (WPS).
  • Input Voltage Selection Switch: Provides versatility to utilize any single- or three-phase North American power (208, 240, 460, 575 V). Location in the wire drive compartment provides the ability to manually switch input voltage. An error will display if wrong input selected.
