Item Details

  • Miller® Millermatic® 355 W/EZ-Latch Running Gear 208/240/460/575V - 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.


  • Easy-to-understand interface - 7-inch color LCD display ensures proper machine setup and parameter selection, reducing setup time and increasing weld time
  • 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.
  • Auto-Set™ Elite offers predefined weld settings to increase ease of use and ensure that the job is done right for operators of all skill levels.
  • 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.
