Issues
Resolvable Methods
Digital display is on, fan is not working
and control knob is not working.
Over voltage protection is working. Turn off
the machine then turn on it again after several
minutes.
Digital display is on and fan is working.
However, while pressing the trigger of
torch, there is no arc-striking and
electromagnetic valve is not working.
1.
Check if torch is well connected.
2.
Check if control knob of torch is damaged.
3.
Part of assistant power module on top PCB
board is damaged and there is no DC 24V
output.
Contact LOTOS for repair.
Digital display is on and fan is working.
However, pressing the trigger of the
torch, there is no arc striking and inter
red LED light is on (need to remove the
cover).
1.
The MOSFET on the top PCB board is
damaged (driver module is damaged).
2.
Voltage rising transformer on the bottom PCB
board is damaged.
3.
Control module is damaged.
Contact LOTOS for repair.
Digital display is on, fan is working and
Airflow comes while press the trigger
on the torch. However, there is no arc-
striking and inter red LED light is not
on (need to remove the cover).
There may be some damage on the PCB board:
1.
Primary coil of arc-striking transformer is
damaged or has poor contact.
2.
Voltage rectifier diode is damaged.
Contact LOTOS for repair.
Pilot arc is not striking when pressing
the trigger on the torch.
1.
Input voltage is too low.
Use a stable 120 V or 240 V power source.
2.
The input air pressure is too high or too low.
Adjust the air pressure.
