0193731301 - ESAB 25A Relay Contactor EH 6-31E Replacement Part

Reliable Power Control for Your Welding Equipment

Keep your industrial welding operations running smoothly with the ESAB Relay Contactor 25A (0193731301). This critical component is a genuine OEM replacement part designed specifically for compatible ESAB welding power sources and wire feeders. Electrical components in welding machines are subject to rigorous duty cycles, thermal fluctuations, and constant switching, which can eventually lead to wear and failure. The EH 6-31E model contactor is engineered to handle these demands, providing a stable and reliable connection for your machine's internal circuits.

When a contactor fails, it can manifest as a machine that refuses to strike an arc, a wire feeder that won't engage, or a unit that hums but produces no output. Replacing a faulty unit with this 25 Amp relay ensures that your equipment switches power accurately and safely. Using genuine ESAB parts guarantees that the mounting points, coil voltage specifications, and amperage ratings match your machine's original engineering requirements perfectly, eliminating the guesswork often associated with universal aftermarket parts.

Whether you are performing routine maintenance or an emergency repair, this relay contactor offers the durability expected from ESAB products. It features high-quality contact materials that resist pitting and arcing, ensuring a long service life even in busy fabrication shops. By choosing the correct replacement part, you protect the downstream components of your welder and minimize costly downtime.
