Miller Millermatic 255 MIG Welder with EZ-Latch Running Gear

Features

• 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.
• 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.
• Versatility: Capabilities include MIG, pulsed MIG and flux-cored welding.
• 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: Will be able to operate and provide full output when powered by an engine-driven welder with 12000 Watt (12K) output or higher, such as a Miller Bobcat or Trailblazer. Limited output will occur when used with smaller generators.
• Locks and Limits: Provides control of the weld parameter ranges minimizing deviations from the welding procedure specifications (WPS).
• USB Port: Provides the ability to easily update software, back-up settings and transfer saved weld programs from one unit to the next.
• Auto-Set™ Technology: Offers predefined weld settings to increase ease of use and ensure that the job is done right for operators of all skill levels.
• Easy-to-understand interface: 7-inch color LCD display ensures proper machine setup and parameter selection, reducing setup time and increasing weld time
• 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.
