Esab 0558-102696 Warrior 400i Mv Multi-process Welder

Product Description

The ESAB 0558-102696 is the Warrior 400i MV, a multi-process CC/CV inverter welder built for heavy-duty industrial and field welding applications. It delivers 400 amps at 60% duty cycle and is capable of up to 500 amps output, making it suitable for extended-duration welds on demanding jobsites. The inverter-based power stage provides improved energy efficiency and a lighter, more portable footprint compared to transformer-based units. The unit accepts a wide input voltage range with auto-sense capability from 208 to 460 volts, 3-phase, supporting use across regional power infrastructures. Licensed welders, pipefitters, and fabricators are the primary installers and operators of this equipment.

The Warrior 400i MV is designed for both indoor and outdoor use in rough environments, backed by an IP23 ingress protection rating. It supports multiple welding processes including stick, MIG, and TIG-compatible modes through its CC/CV output configuration. The Basic Package configuration covers core multi-process welding needs on structural, fabrication, and maintenance applications in industrial, construction, and shipbuilding settings. Its glove-friendly control interface allows quick parameter adjustments even in challenging work conditions.

Installation Notes

Installation and connection to 3-phase power should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Ensure input power is fully de-energized and locked out before making any electrical connections. Verify input voltage supply matches the unit auto-sense range of 208 to 460 volts, 3-phase, before energizing. Proper grounding of the welder chassis is required before operation.
