Why is the higher oxygen pressure needed for cutting and not welding
Give this one a try later!
The oxygen burns the metal, making the kerf
What do you do when piercing a hole in a plate?
Give this one a try later!
Hold the torch perpendicular to the base metal. More heat is required to
preheat the surface when piercing than starting on an edge, so a larger tip
is to be used.
, What procedure of oxyfuel is used to cut cast iron or stainless steel?
Give this one a try later!
The procedure of using a carburizing flame
What will happen if the oxygen cutting valves are not open while adjusting the
oxygen pressure?
Give this one a try later!
The pressure will drop when the valve is opened during the cutting process
resulting in a reduced preheat flame
What are the pressures of the oxygen and acetylene when using a positive-pressure
type torch on a 1/2" thick piece of steel?
Give this one a try later!
Oxygen = 25psi; Acetylene = 3psi
