Esab 0558-102558 Multi-process Inverter Welder 300A

Product Description

The ESAB 0558-102558 is a multi-process inverter-based power source built for MIG, Stick, TIG, and air carbon arc gouging applications. Powered by MiCOR inverter technology, this unit delivers up to 300 amps of output while drawing from 208-230, 400, or 460 VAC input, making it compatible with a range of job-site power configurations. The inverter design reduces overall weight compared to transformer-based units, and the architecture supports the use of longer primary cables without significant power loss. Licensed welding professionals and industrial contractors use this power source for both shop and field work where process flexibility and portability are required.

The 0558-102558 is suited for residential, commercial, and industrial welding applications where a single machine must cover multiple processes. It handles MIG welding with adjustable inductance and gas-mode optimization for CO2 and mixed shielding gases. For Stick welding, it includes adjustable hot start and arc force controls with optimized electrode modes for E6010 and E7018 rods. The lift TIG start function enables TIG arc initiation without high-frequency interference, and a dedicated arc gouging mode supports air carbon arc operations. At under 55 pounds, it is designed for on-site portability and job-to-job transport.

Key Features

• MiCOR inverter technology supports longer primary cables and reduces power consumption by up to 25 percent compared to conventional designs
• Adjustable inductance control with CO2 and mixed-gas selection modes for MIG welding arc stability and spatter reduction
• Adjustable hot start and arc force controls with E6010 and E7018 electrode-optimized modes for Stick welding
• Lift TIG start for arc initiation without high-frequency output
• Dedicated air carbon arc gouging mode
• Multi-voltage input accepts 208-230, 400, and 460 VAC for flexible job-site compatibility

Compatibility

Designed as a standalone multi-process inverter power source for MIG, Stick, TIG, and air carbon arc gouging processes. Specific torch, electrode holder, and work cable compatibility should be confirmed against ESAB accessory documentation for this model.

Installation Notes

Installation should be performed by a qualified electrician or certified welding professional in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all input power before making any electrical connections to the unit. Verify that the supply circuit voltage and ampacity match the machine's input requirements before energizing. Ensure adequate ventilation around the unit during operation as inverter power sources generate heat that must be dissipated.
