2)
Turn on the power switch after installation and connection. Then the power indicator lamp is ON; If the gas
pressure is less than 0.25Mpa, the lamp will be OFF, then the gas supply should be checked;
3)
Start water supply equipment. The indicator lamp of water pressure on panel is ON when opens water supply
valve.
4)
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;
5)
Checking the panel indicator lamps. The indicator lamps status, under which cutting can be operated, is shown
as following sheet.

Gouging operation
1)
Set the function selection switch on panel to Gouging position
2)
Set the basic distance from nozzle to workpiece 3mm, angle α to 35
°
3)
Gouging under 2-step
a)
Press the torch switch without loose, air come out from the nozzle, start indicator on, HF start, arc pilot
b)
Move the arc to workpiece, keep nozzle axle and workpiece angle, move torch with the gouging direction
c)
Loose the torch switch, gouging stop, air continue come out from the nozzle for 7S
4)
Gouging under 4-step
a)
Press the torch switch then loose, air come out from the nozzle, start indicator on, HF start, arc pilot
b)
Move the arc to workpiece, keep nozzle axle and workpiece angle, move torch with the gouging direction
c)
Press the torch switch, gouging stop, air continue come out from the nozzle for 7S
5)
Warning
a)
For different gouging size, it need to adjust the nozzle axle and workpiece angle, but should within 30
°～
45
°
,exact method refer to the gouging surface adjust method and gouging parameter table
b)
For different gouging size, it need to adjust the nozzle and workpiece distance, exact method refer the gouging
surface adjust method, the distance to small will increase the nozzle damage
c)
Normally the electrode life time is shorter than the nozzle during gouging, before operate need check the
electrode and replace it when necessary
Cutting operation
1)
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. To drill 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;
2)
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
