0558002576 - ESAB 24VAC 20A SPST Magnetic Blowout Relay

Get Your Machine Back Up and Running

When your welding machine acts up—whether it's a wire feeder that won't engage or a gas solenoid that's sticking—a faulty relay is often the culprit. The ESAB 0558002576 Relay is a heavy-duty replacement part designed to get your equipment back in the fight. This isn't just a standard off-the-shelf electronics part; it is built to handle the dirty, high-vibration environment of a welding shop. With a 24VAC coil voltage, it fits the control logic of many professional-grade power sources, ensuring your trigger pulls result in immediate action every time.

Why "Mag Blow" Matters

You might see "Mag Blow" on the spec sheet and wonder if it matters. It absolutely does. Magnetic Blowout technology is a lifesaver for relays that handle DC power. When a relay opens to break a circuit, electricity tries to jump the gap, creating a tiny lightning bolt or "arc." This arc burns the contacts, eventually causing them to weld shut or fail to conduct. The Mag Blow feature uses a built-in magnet to literally blow that arc out, just like blowing out a candle. This means your relay lasts longer, handles loads better, and doesn't fail right when you are in the middle of a critical pass.

Installation and Durability

Rated for 20 Amps, this SPST (Single Pole Single Throw) relay is robust enough to handle the power requirements of internal machine components. It is designed for straightforward replacement, minimizing the time you spend with a screwdriver in hand and maximizing your time under the hood welding. Whether you are troubleshooting an older ESAB machine or performing preventative maintenance, swapping out worn relays with high-quality replacements like this one is the best way to ensure consistent arc starts and reliable machine behavior. Don't risk your welds with cheap substitutes; stick to parts designed for the job.
