0459230880MV - ESAB AristoMig 500i Multi-Voltage Inverter Welder Power Source

Heavy-Duty Industrial Power Source

The ESAB AristoMig 500i (0459230880MV) is a premier industrial welding power source designed to meet the rigorous demands of heavy fabrication, shipbuilding, and manufacturing sectors. Engineered with advanced inverter technology, this machine delivers a potent 500 Amps of welding output while maintaining a compact footprint and reduced energy consumption compared to traditional transformer-rectifier units. The "MV" designation signifies its Multi-Voltage capability, allowing the unit to accept 3-phase input power ranging from 208V to 575V. This flexibility makes it an invaluable asset for facilities with varying power infrastructures or for mobile contracting teams moving between job sites with different voltage standards.

Built to withstand harsh industrial environments, the AristoMig 500i features a robust metal casing with an IP23 protection rating, ensuring resistance against dust and water spray. The internal cooling system is optimized to prevent particulate accumulation on sensitive electronic components, significantly extending the service life of the machine. When paired with ESAB’s Aristo Feed wire feeders and U6 or U82 control panels, this power source becomes a fully integrated welding system capable of sophisticated Pulse and SuperPulse applications. These features are critical for industries requiring X-ray quality welds on aluminum, stainless steel, and other exotic alloys.

Efficiency is at the core of the AristoMig design. The inverter topology not only reduces power bills but also improves the power factor, allowing for more machines to be run on the same circuit breaker compared to older technology. For operations requiring high deposition rates, the machine supports carbon arc gouging, making it a versatile tool for weld removal and joint preparation. Whether integrated into a robotic cell or used manually in a fabrication bay, the AristoMig 500i provides the reliability and consistency required for high-stakes production environments.
