Place the gas control switch to “Check Gas”, adjust the Adjusting knob of air filter
regulator to make the output pressure and flux fit cutting condition. After adjusting,
place the knob on “ Cutting “ position. Select panel operation method and control
switch point. At 2-Step point, the torch switch; should be pressed all the time
during cutting. After loosening, the cutting comes to stop. At 4-Step point, press the
torch switch and then loosen it, and cutting can start. User can make selection
according to his operation habit;
6)
Checking the panel indicator lamps. The indicator lamps status, under which cutting
can be operated, is shown as following sheet.

Notes: there is no water pressure indicator on AIRCUT-101I and the water
pressure indicator will be OFF when gas-cooled torch is applied on
AIRCUT161IW/200IW cutter.
7)
Keep the torch nozzle 2mm~ 5mm away from work-piece. The axis line of nozzle
should be perpendicular to work-piece, and starts cutting from the edge of
work-piece. When the plate thickness is ≤12mm, a hole can be drilled on work-piece
and then cutting can be started around the hole. The cutting torch should inclined to
one side a little during drilling a hole on work-piece, so that the molten metal can be
blown away easily. Todrill a hole by use of plasma arc is not proposed, because this
will damage nozzle easily, it is better to drill a hole in arc striking point first, then
strikes arc on the edge of hole. Press down torch switch, compressed gas sprays out
from nozzle, and cutting indicating lamp is ON. After gas pre-flows for 1 to 2 seconds,
high frequency is generated, arc is stroke,and cutting begins by moving torch;
8)
When the control switch of operation method on front panel is at 2-Step point,
press down the torch switch and cutting starts after arc striking. After loosening the
switch, there is no voltage output, and cutting ends, and compressed gas stops
supply in 9 seconds. When it is at 4-Step point, press down the switch and loosen it,
and cutting starts after arc striking automatically. Press the switch again or press it
till the arc is off, then there is no voltage output, cutting ends, and compressed gas
stops supply in 9 seconds.

The related main technical parameters
1) Cutting material and thickness
The selection of cutting technical parameters is based on the cutting material and
thickness. If the material is thick, it should adopt large current and nozzle with big
aperture. For different material under the same thickness, the parameter should also be
different.
2) Nozzle selection
