I am looking for a small torch to carry in my dd truck tool box. I want to be able to do light welding with it. This is nice but its way too much to carry around all the time. I also found this one that uses 16 oz disposable bottles. Obviously it won't weld as thick, and I think I can cut with the first one but not the second one. However its smaller and no regulators to worry about damaging. No messing with refills, Fuel is relatively easy to find. Are there any other alternatives to these two? Something in between or a beefier version of the 16 oz bottle one? Is it possible to get a nicer mini torch, say like this Victor J-40 or J-28 along with a tip and still run it off 16 oz bottles? There actually a mini cutting head for those Victor torches. Would I be able to cut with MAPP and O2? If this is do-able, where would I get the bottle tap valves for the disposable bottles?
