Hi...
I am running a workshop for the past 6 months. I have a doubt that which gas is perfect for Dig welding?
 
Gasoline fueled blowtorches use white gas not automotive fuel. This is what is commonly used in Coleman camping products. About $8.00 a gallon at Walmart for the house brand. I believe it is mostly naptha. I use it to thin oil based paint.
The gas blowtorches are really only used to preheat metal prior to welding or to heat tools for soldering big sheets of metal as in roofing. They are too big a flame for welding and not high enough a temeperature to melt metal other then solder.

lincy, welcome to the forum. This place has an enormous wealth of information to share, but as you can see, it also tends to be impatient when someone asks a broad question but provides limited data.

As others have said, give us some background on what you are welding, which process(es), what sort of equipment.
