I can't tell you other than he talk youStick with propane,its cheaper and easier to get hold of
One thing you will notice you'll use a lot more oxy when cutting with propane than you would with acetylene
Have a look http://www.weldequip.com/propane-regulator-special.htmThe oxygen is cheap enough I don't mind that. The acetylene is 100 euro a fill plus rental every year . The oxygen is 30 euro a fill and I don't mind the rental on the oxygen bottle I need it for heating and cutting anyway. Can I use the acetylene reg with the propane reason I ask is it can't find a propane reg with gauges
