13735102 - ESAB 3PDT Control Relay 42V Coil

Restore Your Welder's Reliability

Is your welder acting up? Maybe the wire feeder clicks but doesn't spin, or the shielding gas refuses to flow when you pull the trigger. Often, these frustrating issues can be traced back to a small but vital component: the control relay. The ESAB 13735102 is the genuine replacement relay you need to get your machine back up and running smoothly. Think of this relay as a traffic cop for your welder's electricity; it takes the low-voltage signal from your trigger and uses it to switch on the more powerful components that actually make the weld happen.

This specific relay is a 3PDT (Three Pole Double Throw) model, which is a fancy way of saying it's a multitasker. When it activates, it can switch three different circuits at the same time. This is crucial for welding machines where pulling the trigger needs to do several things at once: start the gas flow, energize the welding tip, and start the wire feeding. If any one of those 'poles' inside the old relay is burnt out or stuck, you lose that specific function, even if the rest of the machine seems fine. Replacing a faulty relay is often a quick and cost-effective fix that saves you from buying expensive new circuit boards or sending the machine out for costly service.

The ESAB 13735102 is built to handle the tough conditions of a welding shop. It features a 42-volt AC coil, which is the standard control voltage for many industrial machines, keeping the trigger voltage safe for you to handle. The contacts are rated for 10 amps, meaning they are robust enough to handle the power spikes that occur when motors start and stop. The clear or semi-opaque enclosed case allows you to sometimes visually inspect the contacts for arcing or soot, but more importantly, it keeps out the grinding dust and dirt that kills lesser electronics.

Don't settle for generic electronic parts that might not fit or function correctly. Welding machines are tuned instruments, and using the correct OEM part ensures that the timing and electrical resistance are exactly what the machine's computer expects. Whether you are fixing a MIG runner, a TIG cooler, or a heavy-duty power source, this ESAB relay is the direct-fit solution to solve intermittent electrical gremlins. Keep a spare in your maintenance kit so you never have to stop a job waiting for a ten-dollar part.
