I'm currently using an air/acetylene torch for all my soldering and
casting. It works great for the soldering, and ok for the casting,
as long as the casting is less than an ounce. I'm needing to cast
larger quantities than that, so I'm looking at my options.
I've seen a few systems from various jewelry tool suppliers. I've
also seen much less expensive oxy/acetylene welding/cutting setups
from non jewelry tool importers for much less money.
My tool budget is a bit thin, so I'd like to buy as inexpensive a
setup as I can. But I'd rather spend more than I want, then buy
something that does not work.
