Cool down the heat components in the cutting machine.
2. Operating procedure
2.1 After going through periodical check process, power on the cutting machine, then
working indicator will light up and cooling fan will spin.
2.2 Flip the “Gas test/Cutting” switch to “Gas test”.
The gas valve in the machine will turn on and let gas flow up to one minute to remove
condensed water drops accumulating in the torch. Regulate the compressed air filter to
let the hand of air gauge indicate 0.45 Mpa. Then flip the “Gas test/Cutting” switch to
“Cutting”.
2.3 ACUT60 cutting machine applies contact type cutting torch. When cutting, let the
nozzle of torches touch workpiece, then press the torch button to start arc.
ACUT100 andACUT120 cutting machine apply non-contact type cutting torch. When
cutting, keep a distance from 3 to 5 mm between nozzle and workpiece to start arc and
allow no touch between nozzle and workpiece in the process of cutting.
2.4 Usually, cutting begins at the margin of the workpiece. It can also start at any point of the
workpiece, but cutting torch should be tilted a bit to blow molten metal and form the
start point of groove.
2.5 While in cutting, keep cutting torch moving at consistent speed.
2.6 While stopping cutting, move the torch away from woekpiece after the plasma arc goes
out completely. Otherwise the workpiece will be distorted by remained arc.
