Just wanted to know how many others like me have done the cutting torch conversion and if you have any tricks aside from the usual buy the victor tip made for propane.
propane instead of acetylene

You can cut cheaper, you wont be able to weld with it. You need the proper tip for it to run right. Not much else to say except that it saves you a bit of money.

Weve used it, like was said we have a different tip so we can switch between the 2...

I have used propane for years. But I also keep a tank of Acetylene. What do you mean, you can not weld with it? I have no problem welding/fusing light gage sheet metal with it. All you need is the correct size welding tip and the correct pressures for welding.mckutzy

There is some varying schools of thought on propane welding, here is the best example I can think of,
From CNCzone,

"Lots of conjecture out there on why you can't weld with propane. Some say Propane is not hot enough. Actually that has nothing to do with it. Take a #7 Oxygen / Propane tip and compare it to a tiny #1 welding tip. Even though the Propane tip has a far higher BTU output you still will not get a good weld. The reason Propane ( and other alternative fuels ) are not suitable is that when Acetylene is burning with Oxygen it creates a cone of CO2 forming a shielding gas over the weld puddle. Propane does not produce this shielding Co2"

And yet i know many people my self included that have used it to weld with. and cut up to 3/8 steal with my setup. Now granted its not as good as i can do with my plasma cutter but a heck of alot more mobile.
