I was looking to purchase a guys turbo torch. It comes with the quick change handle, a small tip, regulator and hose. The regulator attaches to a Acetylene Btank. The B tanks are expensive and I only wanted to do a small soldering job (1/2 nom fittings), is there an adapter that would allow that regulator to screw onto a Mapp canister. I have looked around but they do not describe the application so I am a little leary to purchase. Anyone know for certain?
