Acetylene is very hard to get right now, my understanding is that the factory that makes the carbide the acetylene producers use to produce the gas blew up at the end of March. Both Air Gas, and Prax-Air will not sell it to non-contracted customers, due to a shortage that is expected last several months to a year. They are recommending using propylene, but I don't know what effect this will have on the welds. Any one have any idea? Otherwise I guess I'll have to figure out how to TIG.
