Wanted Tig Welder In Birmingham

Hi, I've got a problem with my Alfa Brera where one of the air conditioning pipes has been rubbing on the engine cover and worn a little notch in the pipe letting all the air con gas out. A new pipe is over £200 and they are rare second hand. I was a nuclear coded welder back in the 90s and if I had access to a TIG welder I could easily patch it up. Has anyone got a welder I could borrow/use for 30 mins. Happy to supply beer tokens / biscuits or other forms of payment.
Many Thanks
Ian

I've got one you art welcome to use. If you could help me learn to weld that would be good too.
Drop me a PM if you are interested.
Cheers
Grebby (also an Ian)
