Miller Millermatic 255 MIG/Pulsed MIG Welder w/ EZ-Latch Running Gear- 208/240V

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.

Program mode allows easy save and recall of favorite weld settings -
Deliver more productivity, consistent quality by welders of all skill levels by using prequalified weld settings. Minimize supervisor need to intervene.

Auto-Line Technology -
For portability and reliability, this inverter power supply allows for any single-phase input voltage hookup (208–240 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.

Versatility -
Capabilities include MIG, pulsed MIG and flux-cored welding.

MDX-250 MIG Gun w/ 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

Portability - Machine only weighs 84 lb -
Weight is reduced by more than 50 percent compared to the Millermatic 252.

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.

Generator Compatible -
The Millermatic 255 will be able to operate and provide full output when powered by generators with 12000 Watt (12K) output or higher. Limited output will occur when used with smaller generators.
