I’ve got a Kel-Arc in the shed, it’s like the old joke … tried it once & didn’t like it. Bought it about 40 years ago on a whim hoping to weld thin stuff with a arc welder, with the small migs around at a reasonable price now, there is no reason to use one.
Do you want to sell it
There is a copy of the instructions in Post #18 of this thread:
Anyone know what this is?
I think it is some kind of welder but im not sure what. My mate is asking and ive never seen one. Obviously i cant go and have a look due to the current situation Thanks

Where can I find post 18

Still struggling, can only see up to post 9
Thanks, found it
Want to sell it
Can anyone tell me what transformer I should get to use with a rawlplug welder,
And where I can buy one,
Thanks

"Can you tell me what transformer I should get to use with a Rawlplug welder, and where I can buy one?"
The Rawlplug/Kel-Arc/XP welder attachment ( sorry, it cannot really be called a welder....! ) was designed to allow an Arc welder ( or a set of car batteries ) to be used for welding thin metal, by using a "buzzer" to reduce the current by intermittently breaking the arc. Now that MIG welders are available to the hobby market, it is obsolete, and only has curiosity value, as an antique.
It can be supplied by from one to three 12v car batteries. That would total 12 to 36 volts, and be capable of delivering 50 to 200 Amps, if fully-charged and in good condition. Alternatively, a mains transformer with a low voltage high current secondary can be used. I'm not sure what thickness of metal you want to try welding ( need about 30 to 40 Amps per millimetre of thickness ), but as a rough guide the transformer output would have to be about 100 Amps at about 50 volts ( and 230v AC mains input ). This is the middle of the power range specified in the Rawlplug instructions, which offer metal thickness from about 0.8mm ( thin car bodywork ) up to 6mm ( 1/4 inch ).
A transformer of that specification is usually only commercially available when it is classified as a "welder". In other words, you'd be looking for a traditional transformer-based AC Arc welder, commonly known as a "buzz box" ( because they do make a humming noise... ).
For example, here is a 48 volt 110 Amp unit from Screwfix:
www.screwfix.com
This type of transformer is large and heavy ( 10 to 20 kg ) and not very popular today, so there are plenty being disposed of. Try searching for "arc welder" on Gumtree, eBay, etc., and you will probably be able to find a secondhand one on offer locally "for collection only", at around £15. They are just a transformer in a box, with almost nothing to go wrong, so even tatty rusty ones will probably still work OK.
Modern electronics has made transformer-based Arc ( "MMA" ) welders obsolete. Today they are half the size of a shoebox and weigh a couple of kilos. Try searching for "ZX7-200" on eBay. E.G. :
As mentioned, the Rawlplug was an early substitute for a MIG welder. Here is an example of an actual one that is cheap, works OK, and is both a MIG welder and an Arc welder :

Thanks so much for the info, I will take a look,"Can you tell me what transformer I should get to use with a Rawlplug welder, and where I can buy one?"

So are you saying that if I can find a cheap arc welder I can use this to connect to my welders mate rawlplug welder, if so is it a case of connecting the positive of the arc welder to the positive of the rawlplug welder and the negative the the work piece, sorry but I really would like to use my rawlplug old welder,
Thankyou again
