Yesterday I attempted to heat the side of the bucket on my bobcat loader in order to knock some of the dents out of it...I used a rose bud tip on my torch, but I don't think I set the oxy/act correctly..in fact I know I did not set it right..I never did get the metal to really heat red hot and , while the flame looked clean, there was a lot of black soot on the metal. I think I was was way to low on both gas and oxy. I was set at 5 psi gas and 7 oxy. What should I have been set at for a rose bud tip??? metal is about 1/4 thick....
Thanks
