Operation steps of cutting
● After checking all connections, turn on the plasma cutting machine.
● Adjust the power to the thickness you intend to cut.
● Press the cutting switch on the torch, you shall have compressed air coming out of
the nozzle: within 2 seconds the pilot arc will be ignited.
● Get closer to the material, then the pilot arc will be switched automatically to cut-
ting arc.
● As you pull away the torch from the metal sheet, the cutting arc will be switched
back to pilot arc again.
● Now the machine is ready to use for cutting.
● When you release the cutting switch the arc will be shut down immediately.
● After the arc stopped for about 30 sec you will still have air flow from the nozzle to
cool the hot system elements.
