907734 - Miller Millermatic 255 Pulsed MIG Welder 208/240V

Industrial Precision with the Millermatic 255

The Miller Millermatic 255 is a powerhouse inverter MIG welder designed for light manufacturing and fabrication environments where efficiency and weld quality are paramount. Weighing in at only 84 lbs, this machine replaces heavier transformer-based predecessors like the Millermatic 252, offering superior portability without sacrificing arc performance. It is engineered to handle 208V or 240V single-phase input power, utilizing Auto-Line™ technology to ensure consistent performance even on dirty or unreliable power grids often found in industrial settings.

Advanced Pulsed MIG Capabilities

One of the standout features of the Millermatic 255 is its built-in Pulsed MIG capability. For fabrication shops working with aluminum or thin stainless steel, Pulsed MIG is essential. It lowers total heat input, significantly reducing distortion and burn-through on thin materials. Additionally, the reduced spatter generation minimizes post-weld cleanup, allowing your team to focus on welding rather than grinding. When paired with the appropriate shielding gas mixes available from Josef Gas, this machine delivers spatter-free, aesthetic welds that meet high industrial standards.

Intuitive Control and Compatibility

The 7-inch color LCD interface simplifies machine setup through Auto-Set™ Elite. Operators can select their wire diameter, material thickness, and gas type, and the machine automatically configures the optimal parameters. This feature reduces setup time and training requirements. The unit comes equipped with the MDX™-250 MIG Gun with AccuLock™ S consumables, ensuring smooth wire feeding and consistent arc stability. For aluminum applications, the machine features a direct plug for XR push-pull guns, allowing the use of 12-inch spools for extended welding runs.
