I would like a TIG welder, but I am afraid my workshop days are dwindling and I would never get any real use out of it. So I will stick with my MIG. Oxy/Propylene seems to be gaining favour industrially. Propylene gas is much safer than acetylene to store and use, but getting hold of it in small bottles is difficult. I have only found one supplier in Chesterfield. If I went the oxygen concentrator route, then I would probably use the Novacet cans with my Walkover torch, as they seem to last a long time compared to the disposable oxygen bottles.

The problem doesn't need to be resolved until September-ish 2020 when my Glassblower friend retires. Until then I can use his oxy/propane torch for small brazing jobs.

Cheers,
