    Have you contacted Miller's Engine Drive Department, and ask if one is available?

        Miller made an LP version of your gas Bobcat. I'm sure they could sell you all the parts to convert your machine, however, it may be alot more expensive to convert it than to just trade in your gas Bobcat for an LP one, or sell it outright and buy one outright.

          this welder is a steal of a deal if i can find a kit new or used.....heres the reply i received earlier from miller.....




          Doc,

          Thank you for your inquiry.

          Miller Electric does not offer a conversion kit for your machine. I recommend contacting the engine manufacturer for more information.

          Thank you,

            Just for your information, I own a Lincoln 250, LPG power. It has the next size up engine, plus the vaporizer, propane regulator, and propane carborator.

            I suspect, to get an equivalent output LPG engine, takes more than just a conversion kit.
            Obviously, I'm just a hack-artist, you shouldn't be listening to anything I say .....

              Less BTU

              LPG has less BTU's than gasoline, which produces less output as JS pointed out. I believe it produces about 15% less heat (energy) than gas. If you Google search "LPG conversion kit" with whatever engine type you have, many kits are available.

              Let us know what you find!

              Good luck!

                Actually propane has more BTU's per pound and is around 104 to 107 octane.
                Its natural gas that has less BTU's than gasoline.

                C&P from propane gas assn:
                Propane
                1 pound = 21,500 BTU <-------
                4.24 lbs = 1 gallon
                Natural Gas 1 cubic foot = 1,050 BTU
                36.39 cubic feet = 1 gallon
                Gasoline
                1 pound = 19,000 BTU <-------
                1 gallon = 6.1 lbs

                We have ordered some kits from these guys in the past, and they were bolt up complete, and not to bad on pricing.
                Your mileage may vary, LOL!

                      I talked to these guys awhile back about a conversion for my Hobart. I think it was around $250.00. for the Kohler CH 23.
