ESAB powercut 650 Instruction Manual page 112

SECtIoN 4
NotE: Lower the air pressure to 5.2 bar (75 psig) on
materials < 1.6mm (1/16") or when inconsis-
tent arc starting is experienced at 5.5 bar (80
psig).
NotE: The speeds given here are typical for best
quality cuts. Your actual speeds may vary
depending on material composition, surface
condition, operator technique, etc. If cutting
speed is too fast, you may lose the cut. With
slower speeds excessive dross may accumu-
late. If speed is too slow, the arc may extin-
guish. Air cutting typically produces a rough
face on stainless steel and aluminum.
