steve b Posted May 14, 2020 Share Posted May 14, 2020 Is it just to switch the wire feed and gas solenoid ? Do you know what voltage it operates on ? There must be something Industrial that will replace that , contactors are used in so many applications . Might be worth asking on the MIG welding forum too . cheers Steve b 1 Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted May 14, 2020 Author Share Posted May 14, 2020 Yes just for wire feed and gas has 9a 600vac written on it regards Stephen Quote Link to comment Share on other sites More sharing options...
steve b Posted May 14, 2020 Share Posted May 14, 2020 Have a look on RSComponents www.rs-online.com for contactors , set the filters to what you need . 890_4238 looks promising? cheers Steve b 1 Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted May 14, 2020 Share Posted May 14, 2020 Local electrical factors should be able to match it - that's what I did when the one in my lathe gave up. Cost me all of about £30. Think the one in my welder has given up now too - mind you, date code says 1974 so I've had some mileage out of it! 1 Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted May 14, 2020 Author Share Posted May 14, 2020 One of the sparks from work is going to look at it tomorrow my problem is that it may be a fault in circuit board that's causing the contactor to drop out and if it's anything to do with board I'm just gonna buy a new welder regards Stephen Quote Link to comment Share on other sites More sharing options...

Talking of mileage... if the welder is that old, I wonder how many miles of wire have been through it in that time Quote Link to comment Share on other sites More sharing options...

If I was local I'd offer to nip round with the soldering iron and take a look! 1 Quote Link to comment Share on other sites More sharing options...

Stellaghost Posted May 16, 2020 Author Share Posted May 16, 2020 It's alive !! Working great so far this morning when looking at stuff inside I noticed a plastic electrical gizmo was not connected to rail properly when I tried to re- fix it found a wire had snapped from soldered connection probably giving me an intermittent connection ( left hand orange thingy showing loose with soldered connections behind it ) anyway re- soldered and seems to be working fine at the moment fingers crossed thanks for assistance given guys regards Stephen 1 Quote Link to comment Share on other sites More sharing options...

Stellaghost Posted May 17, 2020 Author Share Posted May 17, 2020 Cheers John took on board what you said about the older transformer welders definitely worth repairing and keeping as long as I can as said previously this is the first problem I've had in nearly 30yrs of use and believe me it's used constantly been the best £500 I've ever spent and even then it was an ex display model regards Stephen Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted November 23, 2020 Author Share Posted November 23, 2020 (edited) So my cebora ceased to work, contactor stuck in and wire live all the time, freed contactor off and welder not working at all with regard to wire going live to weld feed still working got a new contactor from city electrical factors and a separate 24v coil put it together and now working better than ever, how's that your asking, since I moved into present house welder would not work on highest setting and only for a limited time on setting no5 ,I put it down to modern sensitive rcd's, now it works great on all settings, all the signs were there in hindsight I just didn't see them, my original contactor would be around 25/28 years old and contacts would have been burnt after that much use so all good now, hopefully some of you might find this helpful in the future regards Stephen Edited November 23, 2020 by Stellaghost 1 Quote Link to comment Share on other sites More sharing options...

oneandtwo Posted November 24, 2020 Share Posted November 24, 2020 I have just serviced my 1987 Cebora spot welder, that thing is built to last forever, the contactor is designed to be serviced with quick release contacts that allow them to be cleaned off if burnt and refitted in seconds. Trouble is that it does trip modern RCDs instantly, they are too sensitive for welders. Quote Link to comment Share on other sites More sharing options...
