Why the maximum discharge rate should not be exceeded? a. Acetylene becomes unstable and could explode when compressed to high pressure b. It may create a reaction between the flame produce and the amount gas being discharged. c. It causes overheating on the welding tip that will damage the work. d. The working pressure will not stabilize and eventually produce a irregular flame.
