The last HF catalog got had 2 different oxy/acet torches in it.
One was the small, Little Torch, sized one that used disposable oxy
& propane/MAPP gas canister. If I were you, I’d stay away from this
one. Replacing the empty oxy canisters will bankrupt you.
The same catalog had a larger welding set that came with 2 larger
refillable tanks. If I remember correctly, the acet tank was the MC
tank & the oxy was a 40 cu ft. tank. The welding torch was a full
sized torch with changeable tips.
While the torch from the 1st set would be nice for gold work, the
tanks are too small. The tanks from the 2nd set are convenient for
jewelers, but the torch is to big for most work. Too bad they don’t
offer a mix of the small torch & large tanks.
Check with a local welding supply for tanks & regulators. The Little
Torch may be available from them also. but most likely you’ll have
to get it from a jeweler’s supply.
A torch, regulator & set of tanks is a once in a lifetime buy. Get a
good one the 1st time. It’ll cost less in the long run.
