The broken power supply is now fixed. I think the failure may have been due to a tear in the silicone sleeve insulating the power switching transistors. May be worth replacing this in both supplies with something untearable.
The welder that's been donated works, has a big spool of wire and a regulator for disposable bottles. We only need some more gas and the PPE (most notably a face shield) to make it usable. Disposable gas bottles are OK to start with but you need to pretty well supply your own for each job as they won't last long. If anyone has some scrap steel for practicing on, please bring some bits along. Not galvanised steel, please.
