gasoline welding torch

gasoline/Oxy will have theroretical flame temperature close too Mapp/Oxy. To increase the output BTU then adding 10% alcohol should work well as increasing the orifice size for gas welding.

Although it will be close, there's no known subsitute for Acet/Oxy for gas welding.

One could use a Coleman camp stove generator or lamp for a "gas" source. I can't see paying the $700 bucks in parts.

Gasoline vapor will use about 90% less volume than acetylene to accomplish the same job for heating. Overall efficientcy will be less than Acetylene tho.

I've heard of oxy/gasoline cutting torches, but I don't remember ever hearing them described as welding torches. None of the other fuel gases except for acetylene produces enough heat for welding, but most of them allow brazing. Without specific information about the amount of heat gasoline produces, I'd be inclined to suspect that it might not qualify as a welding gas either. If welding is a requirement of your selection, be sure to find out if gasoline will do it. As several others have already mentioned, oxy/gasoline setups aren't cheap.
