I'm based in Stoke on Trent so not too far from you. May be interested in patching it up for you or giving you a few welding pointers to do it yourself. I'm a fabricator / welder by trade.
I know someone that may be interested. I'll speak to him today. This is suitable for ally isn't it?
I don't know much about Tigs but the guy it's for knows even less! He wants one for refurbing alloy wheels. We're based in Newcastle Under Lyme too.
