Millermatic 255

907734/ 907964

Designed for professionals working in the light manufacturing and fabrication segments who want a smaller, more versatile welder with intuitive setup to increase productivity and efficiency. Easy-to-use 250-amp inverter welder improves uptime and performance. Integrated on running gear, this welder can easily be moved around a work cell or can be quickly disconnected, making it portable, which makes integration into a work cell or working in confined spaces a breeze.

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.
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).
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 ensures proper machine setup and parameter selection, reducing setup time and increasing weld time
Program mode allows easy saving and recall – delivers more productivity and consistent quality for welders of all skill levels by using prequalified weld settings. Minimizes the need for supervisors to intervene.
Portability – machine weighs only 84 lbs. – Weight is reduced by more than 50 percent compared to transformer welding machines.
USB Port – Provides the ability to easily update software, back up settings, and transfer saved weld programs from one unit to the next.
