5. ANOMALIES. PROBABLE CAUSES, POSSIBLE SOLUTIONS.
SYMPTOM.
ANOMALY
PROBABLE CAUSE.
POSSIBLE SOLUTION.
There is no voltage in the machine.
Change the intake and/or power supply
hose. Observe if any of the
magnetothermals have “tripped".
Mains voltage > 380 V.
Check power supply voltage
NOTHING
WORKS.
Faulty ON/OFF switch.
Replace ON/OFF switch.
Low magnetothermal switch.
Change for another with a larger calibre.
Cut at lower current levels.
LIMITER TRIPS.
There may be a short-circuit.
Disconnect the machine from the mains
and verify power supply hose.
Overheated equipment
Wait until the equipment cools down
THERMAL LED ON
Mains voltage > 265 V.
Check power supply voltage.
NO PILOT ARC
AND
COMPRESSOR LED
ON
High Heating Of Compressor.
Lack of pressure
Wait to refrigerate the compressor, the
system will become operational once it
goes off the indication bright
Badly fitted electrode or none has
been fitted.
Fit electrode
NO PILOT ARC
AND
ACCESSORIES LED
ON
Electrode or nozzle very worn
Change accessories
NO PILOT ARC
AND ACCESSORY
LED FLASHING
You forgot the air diffuser
Fit the diffuser
NO PILOT ARC
AND CUTTING
VOLTAGE LED
NOT ON
Nozzle-support badly fitted.
Correctly fit the nozzle-support
You forgot the Ground
Place ground on part to be cut
THERE IS PILOT
ARC BUT DOES
NOT CUT
High cutting speed
Reduce speed
Low mains voltage
Verify equipment power supply
THERE IS PILOT
ARC BUT DOES
NOT GO OFF
Very high pressure
Lower pressure in torch
BOTH AT THE START AND END OF A REPAIR, CHECK THE EQUIPMENT INSULATION LEVELS. DISCONNECT
THE ELECTRONIC PLATES WHEN MEASURING THE INSULATION
BLOW THE INSIDE OF THE EQUIPMENT WITH COMPRESSED AIR.
The insulation measuring device will have a voltage of 500 Vcc and will be applied at the following points of the
circuit:
- Power supply - Earth: Ra > 50 Mohms.
- Welding - Earth: Ra > 50 Mohms.
-
Power supply - Welding: Ra > 50Mohms.
