907716002 - Miller Maxstar 400 DC TIG/Stick Welder CE Model

Industrial DC TIG and Stick Welding Power Source

The Miller Maxstar 400 (Auto-Line 380-575) CE is a premier industrial welding solution designed for heavy fabrication, pipe welding, and precision manufacturing. Engineered with Miller's advanced inverter technology, this power source delivers a massive 400 amps of output at 100% duty cycle, ensuring continuous operation in the most demanding environments without overheating or thermal shutdown. This specific model is CE compliant, meeting rigorous European safety and performance standards, making it a suitable choice for international projects or facilities requiring CE certification.

A standout feature of this unit is the Auto-Line™ Power Management Technology. This innovation allows for connection to any input voltage within the 380-575 V range, three-phase, without manual linking. This provides exceptional flexibility in facilities with varying power infrastructure and ensures the arc remains steady even if the input power fluctuates—a common occurrence on large job sites or when running off generators. The machine's energy efficiency is significantly higher than older rectifier technology, translating to lower utility costs over the lifespan of the equipment.

The Maxstar 400 is not just powerful; it is designed for integration and reliability. It features a Cooler Power Supply (CPS), an integrated 120-volt dedicated-use receptacle to power the Coolmate™ 3.5. The power switch on the Maxstar activates the receptacle, ensuring the cooling system runs only when needed. Weighing in at approximately 134 lbs (61 kg), it offers a high power-to-weight ratio, allowing for easier transport around large shop floors compared to traditional heavy iron-core machines. For industrial MRO and fabrication, the Maxstar 400 represents a capital investment in reliability, versatility, and arc quality.
