In a gas cut plate, the cut shows grooves and has deep drag lines. This is due to

tip too close to the cut surface

too much travel speed

less oxygen pressure

smaller size cutting nozzle

less preheating flame

impure cutting oxygen

too slow cutting speed

smaller size cutting nozzle

thickness of metal to be cut

purity of oxygen

duration of cut

type of cutting blowpipe
