),
not Loose
.
●
Connect the Cutting torch to
Output(
－
) or
connector of the Cutting torch,
not Loose
.
●
Connect the air tube to the copper nozzle of the back
panel
. The air supply system should be well connected in
order to keep air output, which is of critical importance for cutting operation.
●
Be sure tha t connection s are correct and not Loose.
●
Turn on
the power
supply
ON/OFF switch.
●
Set CHECK AIR
，
Check Air
flow
and pressure !
●
Set CUTTING,the cutting process will be carried out by using the
torch
switch.
●
To increase the quality of cutting, earth clamp on the work piece should be clamped tightly and as close to the
cutting area as possible.
2.3.3 CONNECT TO THE REGULATOR AND AIR SUPPLY
●
Connect the air regulator to the Cutting machine. Connect the air regulator to the air supply.
●
Connect one end of the air regulator to the air supply inlet of the cutting power source. The other end is for
connecting the hose to the air supply.
●
Screw the air hose pressure regulator and open the air supply.
●
Setting of the Air flow with the adjustment valve of the regulator.
Usually,the valve is about 0.17m
3
/min
.
3. USAGE INFORMATION
3.1 THE POWER SOURCE FRONT PANEL
●
On the front control panel of the cutting power source,there are Pilot lights,check air and cutting switch,Cutting
current controller,etc.
●
A: Cutting current
adjustment knob
or controller.
●
LED1
（
POWER
）
: Pilot light of the power supply in the ON/OFF power source switch. The LED1 is lighted
when the
switch is ON.
●
LED2
（
O.H
）
: Pilot light of Over-heating , Over current or voltage.The LED2 is lighted with thermal overload
protection or over current.LED2 is on, in case that this cutting equipment is of overheating protection status.
Overheating arises if this cutting power source is overloaded. This cutting equipment automatically restarts
when the temperature inside of this cutting equipment has fallen, and pilot lamp is off.
●
LED3
（
LOW INPUT
）
:
P
ilot light of low
power
supply voltage or low voltage
protection
.
The LED3 is lighted
when the
power
supply voltage
is
low
.
CAUTION :
In case that this cutting equipment is of over current or voltage protection status, LED2 is on. At
this time ,Switch of the cutting power source must be turn off,and then Switch should be turn on,the cutting power
source would
be able to cut.
3.2 ADJUSTING THE AIR FLOW FOR THE CUTTING PROCESS
●
Setting of the Air flow with the adjustment valve.
Usually,the valve is above 0.17m
3
/min
.
3.3
Arc starting for the cutting process
Press the torch switch
.
The arc is made between the work and the cutting torch, and cutting operation is
accessible.
3.4 ADJUSTING THE CUTTING CURRENT
The cutting current is selected according to the thickness of the work piece.
