I think what Wozzaah was asking what is the make and model of the unit and what out put current is it rated to. Ie make esab model caddy output 160.The welder is an ARC and MiG welder using 10A and size 8 wire. Its been working for years but hasn't been used since the new PCB was put in. Approx 6 months ago, he said he just never got round to trying it. Dad's a retired electrician and career tinkerer so he's forever welding one thing to another but has been using hi smaller arc welder more recently. There is a possibility he's set something wrong as he is a bit soft these days, so any suggestions of things he could check would be very much appreciated. I realise there's probably hundreds of things it could be and I'm being tremendously vague so thank you for your patience.
hum I use 5.3 amps to close the joints on my butties silver foil, maybe I need to lift the voltage a little.?10 amps is not a welding current unless your welding Kitkat rappers
