Component ID and replacement

Post by teecee90 » Sun Mar 24, 2019 11:35 pm

Can anyone help me identify and source replacements for these components (capacitor and relay - photos attached) from my welder?

Many thanks

As you can see, the relay has 6 pins but most of the ones I’ve been able to find are 8 pin.

Lead spacing on the cap is 22.5mm and physical size is 26.5mmx8.5mmx17.2mm (L/W/H)
Lead spacing (pitch) for the relay is 7mm and physical size is 28.5mmx12mmx25mm (L/W/H)

Google is the universal guru. Look up "finder 40.61", and look for a 250V 16A contact set. Get a specification if poss. Sometimes manufacturers will omit unused pins.

The capacitor should be equally easy to find - it is probably a 0.22 microfarad job, but there is no indication of the voltage it will stand. Do you know whereabouts it is in the circuitry? If it is close (electrically) to the relay, it is probably some form of suppressor, and will therefore need to be a cap specially made for use where the mains is being switched. Check with the supplier.

The relay is available from places like Amazon in 8 lead. Just cut off the leads you don't want, close to the relay cover, and cover them with one of two layers of insulating tape. As for the capacitor I have to guess, that it is a 630 volt suppressor for the contacts on the relay to stop arcing.
