If you head south along the boulevard all the way to the end, hang a left over the bridge, keep going about 200m, there is a work shop on the right, they have Tig welding machine so I've be told.
I've been there before to get a cheap m/c flywheel holder made. I thought when I asked about welding Al last time they were speaking of a wire feed welder. But I'll stop by and ask.
