0558001574 - ESAB 40A 600V Replacement Power Switch

Reliable Power Control for Industrial Equipment

The ESAB Power Switch (0558001574) is a critical component designed to manage the electrical input of high-performance welding and cutting machinery. Rated for 40 Amps and up to 600 Volts, this switch is engineered to handle the substantial power loads required by industrial power sources. Whether you are operating a heavy-duty MIG welder, a precision TIG machine, or a plasma cutter, the main power switch is the gateway to your machine's operation. Over time, mechanical wear, dust ingress, and electrical arcing can degrade the performance of a switch, leading to intermittent power issues or complete failure. Replacing a faulty switch with this genuine ESAB part ensures your equipment operates safely and reliably.

Genuine OEM Quality

When it comes to electrical components, especially those handling 600V, quality and fitment are non-negotiable. This switch is an original equipment manufacturer (OEM) part from ESAB, guaranteeing that it meets the exact specifications of your machine.
