I'm trying to practice butt welding 19 gauge Sheetmetal with my Henrob/Dillon/Cobra torch. I'm using the smallest tip like the youtube videos suggest. I have a low pressure oxygen regulator, and a Smith acetylene gas saver. I set it up with a slightly carborized flame again like the youtube videos suggest. I get 2 or 3 spots welded when the acetylene gas flow drops and the flame on the pilot light on the gas saver gets smaller??? My acetylene regulator is a smith and only a couple years old. Do l need a "special" regulator for acetylene with this torch?

Thanks for the help.

I have an old Henrob setup and didn't get anything new as far as regulators are concerned, just running low pressures like the book suggested. Can't remember what they are without running to the barn, but did follow the book settings. No issues with welding or cutting.
