I'm trying to fix a Britweld 240 MIG that I've recently acquired. I've found out that it's exactly the same board as in a Murex Tradesmig 230 (probably a bunch of others too). Apart from the fan coming on, pretty much nothing works. I've deduced that it's a fault on the control PCB. I've just ordered a bunch of transistors and other compents to start replacing them one by one. However, if anybody has one of these boards knocking around, I'd be prepared to buy it from them. Or even a circuit diagram.... anything!! Failing that, if anyone has a welder with one of these boards fitted I need to know the value of resistor R26. It's been replaced at some point, but I'm not sure it's the correct one. The information on the board is "Elresta Wien W22 4273882". A quick Google on this turns up nothing useful.
Here are a few photos of the board and of the welder itself....

There's also been a repair made to a track on the back side, but this looks OK....
