907728 - Miller Multimatic 255 Multiprocess Welder 208-575V

Industrial Versatility with the Miller Multimatic 255

The Miller Multimatic 255 Multiprocess Welder (907728) is engineered for professionals in MRO, fabrication, and manufacturing who demand versatility without compromising on power. Weighing in at just 84 lbs, this inverter-based power source is less than half the weight of traditional transformer machines, yet it delivers a robust 350 Amps of maximum output. It is a true multiprocess solution, capable of MIG (GMAW), Pulsed MIG (GMAW-P), Stick (SMAW), DC Lift-Arc TIG, and DC Pulsed TIG welding, making it an indispensable asset for diverse welding applications.

Advanced Pulsed MIG Capabilities

One of the standout features of the Multimatic 255 is its built-in Pulsed MIG capability. This process provides lower heat input, which is critical for minimizing distortion on thin materials and controlling the weld puddle in out-of-position welds. Additionally, Pulsed MIG significantly reduces spatter, thereby cutting down on post-weld grinding and rework time. This feature allows operators to perform high-quality welds on aluminum and stainless steel that were previously difficult to achieve with standard MIG processes.

Intelligent Power Management

Equipped with Miller's Auto-Line technology, the Multimatic 255 offers unparalleled flexibility in power connection. It automatically connects to any single-phase input voltage ranging from 208V to 575V without the need for manual linking. This makes it an ideal solution for job sites with "dirty" or unreliable power. Furthermore, the machine is generator compatible, capable of operating at full output when powered by generators rated at 12,000 Watts or higher.

User-Centric Interface

The machine features a large 7-inch color LCD display that simplifies setup and parameter selection. With Auto-Set Elite, operators can access predefined weld settings for MIG, Pulsed MIG, Stick, and DC TIG processes by simply entering material thickness and wire/electrode diameter. For advanced users, the interface allows for fine-tuning and the ability to save up to four custom programs per process, ensuring consistent quality and reducing setup time for recurring jobs.
