OVERVIEW

Industrial Powerhouse for Heavy Manufacturing

The Miller Maxstar 800 is engineered to meet the rigorous demands of heavy industrial manufacturing, shipbuilding, and infrastructure projects. As a high-amperage DC TIG and Stick power source, it delivers up to 800 amps of output, capable of welding materials up to 1 inch thick. For facility managers and procurement specialists, the Maxstar 800 represents a strategic investment in versatility and energy efficiency. The unit features Miller's proprietary Auto-Line Power Management Technology, which allows for seamless connection to any input voltage ranging from 208 to 575 V, single or three-phase, with no manual linking required. This flexibility ensures the machine can be deployed across various job sites or facility zones with differing power infrastructures, making it an ideal solution for environments with dirty or unreliable power.

Operational efficiency is further enhanced by the Cooler-On-Demand feature. This intelligent system operates the auxiliary cooling unit only when necessary, significantly reducing airborne contaminants pulled through the cooler, lowering noise levels, and conserving energy. The integrated Cooler Power Supply (CPS) provides a dedicated 120-volt receptacle for the Coolmate 3.5, simplifying cable management and ensuring the cooling system activates in sync with the power source to prevent torch failure. Furthermore, the machine is designed for longevity and adaptability; a front-panel memory card data port allows for easy software upgrades, ensuring your equipment stays current with the latest Miller technologies without the need for hardware replacement.

The Maxstar 800 is built to streamline workflow in high-volume environments. With 9 independent program memories, operators can save and recall specific parameters instantly, reducing setup time and ensuring consistency across shifts. Whether utilized in aerospace, railcar construction, or high-purity processing, this machine delivers the reliability and power required to maintain production schedules and quality standards.

FAQ

The Maxstar 800 features Auto-Line technology, allowing it to accept any input voltage from 208 to 575 V, single or three-phase, without manual linking.

No, the Maxstar 800 is a DC-only machine designed for steel, stainless steel, and other ferrous metals. For aluminum welding, an AC/DC machine like the Dynasty series is required.

The machine provides a maximum output of 800 Amps.

Yes, it includes a Cooler Power Supply (CPS) receptacle to power a Coolmate 3.5 and comes with a water-cooled thread lock torch adapter. The cooler itself is sold separately.

Pulsing up to 5000 PPS increases arc stability, reduces heat input (minimizing distortion), and can increase travel speeds.

Yes, a front-panel memory card data port allows for easy software upgrades and feature expansions.

The Maxstar 800 is covered by Miller's True Blue 3-Year Warranty.

Yes, the Maxstar 800 is capable of Air Carbon Arc (CAC-A) gouging with carbons up to 3/8 inch thick.
