Miller 246570 Enclosed Relay 24VAC SPDT 30A

Restore Your Welder with the Miller 246570 Replacement Relay

Is your Miller welder acting up? Electrical issues can often be traced back to a failed relay. The Miller 246570 Relay is a heavy-duty, enclosed replacement part designed to get your machine back up and running smoothly. Relays are the workhorses of your welder's internal electronics, constantly switching circuits on and off to control fans, gas flow, or power output. Over time, the mechanical contacts inside can wear out, pit, or stick, leading to erratic behavior or total machine failure. Replacing a worn relay with this genuine Miller part is a cost-effective way to extend the life of your equipment.

This specific relay features a 24VAC coil, meaning it is activated by a low-voltage signal from your welder's control board. Despite the low control voltage, it is built to handle significant power, boasting a rating of 30 Amps at 240 Volts AC. The Single Pole Double Throw (SPDT) design means it has one input terminal and two potential output terminals (normally open and normally closed), giving it the flexibility to handle complex switching tasks. The "enclosed" nature of the relay means the sensitive moving parts are housed inside a plastic shell, shielding them from the inevitable shop dust, metal shavings, and grinding debris that can cause open-style relays to fail prematurely.

Don't risk your expensive welding equipment with generic, universal relays that might not match the exact impedance or switching curves of the original. The Miller 246570 is engineered to the exact specs of your machine. It features a panel mount configuration for easy, secure attachment inside the cabinet. If you are experiencing issues like a fan that won't turn off, a gas valve that won't open, or a contactor that won't pull in, check your service manual to see if the 246570 relay is the culprit. Swapping out a bad relay is often a straightforward repair that can save you the cost of a new machine.
