Do I have to use a regulator?
I have my propane tank hooked up to my burner and it seems to be working fine. I am reaching welding Temps.
I do not understand what the regulator does. I have read hundreds of treads on making my forge and I see 0 to 20 for 1 burner and 0 to 30 for double burner. But I see nothing that tells me why I even need a regulator.
I feel my ignorance could get me in trouble or hurt so I am asking this stupid question what does a regulator do and why do I need 1.
