5. ANOMALIES. PROBABLE CAUSES. POSSIBLE SOLUTIONS.

SYMPTOM. ANOMALY.
NOTHING WORKS.
LIMITER TRIPS.
THERMAL LED LIGHTING
NO PILOT ARC AND
PRESSURE LED ON
NO PILOT ARC AND SAFE
VOLTAGE LED ON
THERE IS A PILOT ARC BUT IT
DOES NOT GO OUT
THERE IS PILOT ARC BUT IT
GOES OUT
BOTH AT THE START AND END OF A REPAIR, CHECK THE EQUIPMENT INSULATION LEVELS. DISCONNECT
The insulation-measuring device will have 500 V D.C. and will be applied to the following points of the circuit:
Power supply - Earth tap: Ra > 50 Mohms.
- Cutting operation - Earth tap: Ra > 50 Mohms.
- Power supply - Cutting operation: Ra > 50 Mohms.
PROBABLE CAUSE.
The machine has no voltage.
Mains voltage out of range
ON/OFF switch faulty.
Magnetothermal switch has low
gauge for the case.
There may be a short circuit.
Equipment overheated.
Mains voltage out of range
Lack of pressure
Retaining cap incorrectly
positioned
You forgot to connect the ground
clamp.
The cutting speed is very high.
Low mains voltage.
The working pressure is very high
THE ELECTRONIC BOARDS WHEN MEASURING THE INSULATION.
BLOW THE INSIDE OF THE EQUIPMENT WITH COMPRESSED AIR.
GALA CUT 700
POSSIBLE SOLUTION.
Change the tap and/or the supply hose.
Observe if any magnetothermal has
"blown".
Check supply voltage.
Replace ON/OFF switch.
Change the magnetothermal for another
larger gauge one. Cut-off at lower current
levels.
Disconnect the machine from the mains
and check the supply hose
Wait until the equipment cools down.
Check supply voltage.
Provide air and regulate. (Minimum at 4.0
Bar)
Place it in its correct position.
Connect the ground clamp to the piece to
be cut.
Reduce the speed.
Check the equipment power supply
Lower the torch pressure
