(1). Connect the machine correctly according the sketch. And switch on the air compressor until to
its rated pressure. It will be turned off automatically to adjust the air pressure-reduced valve to the
proper value.(0.25-0.5MPa generally)
( 2). Join the power switch of the cutting machine. The power indication lamp lights.The cooling
fan begins working. Put the function switch in the position of "air testing" .Then the airspouts from
the cutting torch. put the function switch in the position of " cutting", and press the torch switch.
The air spouts from the torch also.
(3). Selecting suitable cutting current and air pressure according to the thickness and material of
the workpiece and the cutting speed.The selecting standard for the spray nozzle of the torch:
The spray nozzle not change color while cutting.
(4). CUTTING: Hold the cutting torch in the beginning position, and let the nozzle towards the
workpiece with 15
angle of inclination. The nozzle touches the workpiece, and press the torch
switch, Now flow the air first and high frequency arc generated.The high frequency can be cut
off automatically after the arc generation ,Begin to move the cutting torch after the workpiece is
