The system blowing automatically when start or during switch the gas process;Blow time 20s, divided into 2 steps:
Preflow gas(10s) and cutflow gas(10s).
3. Error code and trouble shooting
1) Repair for error code trouble
One the panel, it will show the error code, under the display, three indicator“A”
、
“L/min”
、
“
℃
” all off
。
According to the
following table to repair the machine
：
Code Name Detail Measurement
009
Flow switch
test
After 30min without
start signal, restart the
machine, it indicate the
flow switch testing
No need any measurement, wait until the error disappear
024
No main
machine
current
After Arc transfer,no
main machine current .
1.Check the consumables
2.Check cutting gas pressure value in correct setting.
3.Check arc and workpiece in good connection during cutting.
025
No deputy
machine
current
After Arc transfer,No
deputy machine
current.
1.Check the consumables
2.Check cutting gas pressure value in correct setting.
3.Check arc and workpiece in good connection during cutting.
027
Lack phase
3 phase power supply
not stable.
1.Check the phase of power supply where in correct.
2.Turn off power,check contactor tip damaged.
3.Check the connection of power cable,contactor cable
whether in good status.
032
Pause overtime Pause signal expire
time over 60s.
1.Check X6 cable at back of power source whether damaged.
2.CNC still maintain the signal,may wait for another torch initial
location signal.
3.If the CNC interface cable is working and only have one
torch,shall replace PCB board for plasma Power source.
044
Plasma gas
pressure too
low
1
、
Plasma preflow
pressure less than 5PSI
2
、
Plasma cutting flow
pressure less than
0.2MPA
1
、
Check the gas supply, make sure the pressure enough
2
、
Check the pressure adjust set on the gas console according to
the cutting table
3
、
Check gas pressure switch damage or PL18 damage
046
Lack voltage
Power supply of cutting
power source less
(rated input
voltage)*15%
1.Check the input cable voltage in range rated input
voltage-15%
2.If input voltage is normal,PL18 or PL03 shall be
problem,replace the PCB of the plasma power source.
047
Over voltage
Power supply of
cutting power source
higher than rated input
voltage*18%
1
、
1.Check the input cable voltage in range rated input
15%
2.If input voltage is normal,PCB shall be problem,replace the
PL18 of the plasma power source.
050
Power input
signal error
During power on,CNC
output signal is
available,such as turner
signal,piercing
signal,pause signal and
start signal.
1.Stop or clear cutting program.When finish cutting,the start
signal still not disconnection.
2.Check the cable from CNC to power source whether
damaged.
