GALAGAR GAR CUT 2500 Manual De Instrucciones página 25

SYMPTOM. ANOMALY.
THERE IS PREMATURE WEAR OF
THE CONSUMABLE ELEMENTS.
THE FAN DOES NOT START UP
WHEN THE MACHINE IS
CONNECTED.
SPECIALIZED PERSONNEL MUST CARRY OUT ANY WORK ON THE EQUIPMENT.
BOTH AT THE BEGINNING AND END OF A REPAIR CHECK THE EQUIPMENT INSULATION LEVELS.
DISCONNECT THE ELECTRONIC BOARDS WHEN MEASURING THE INSULATION.
The insulation-measuring device will have 500 V DC and will be applied to the following points of the circuit:
- Intake rectifier-Earth: Ra> 50 Mohms
- Outlet rectifier-Earth: Ra> 50 Mohms
- Switch l2 - Outlet rectifier: Ra> 50 Mohms
- Control circuit-Earth: Ra> 50 Mohms
In the event that lack of insulation is observed it is likely that this is due to the accumulation of metal dust on
the inside of the equipment.
BOTH AT THE BEGINNING AND END OF A REPAIR, BLOW THE INSIDE OF THE EQUIPMENT WITH
ELECTROMAGNETIC COMPATIBILITY (CEM).
The user is responsible for the installation and use of the welding material according to the instructions in
this manual and the following recommendations.
Before installing the welding material, the presence of the following in the surrounding area must be kept in
mind:
• Wiring for power, control, signalling, and telephones.
• Radio and television receivers and transmitters.
• Computers and other control equipment.
• Critical security equipment.
• People with pace makers or hearing aids.
• Measurement and calibration equipment.
In order to reduce EMC problems, keep in mind the time of day when welding or other activities will be
carried out. Move possible interference victims away from the welding installation.
ALWAYS CONNECT THE MACHINE TO POWER USING AN EFFICIENT EARTH TAP.
IF PROTECTIVE DEVICES OR SUPPLEMENTARY ELECTRICAL SYSTEM FILTERS ARE NEEDED, CONSULT OUR
PERFORM THE MAINTENANCE OPERATIONS DESCRIBED IN THIS MANUAL.
USE THE SHORTEST WELDING WIRES POSSIBLE AND KEEP THEM PLACED NEXT TO EACH OTHER NEAR THE
IF THE WELDING PIECE IS GROUNDED, KEEP IN MIND OPERATOR SAFETY AND NATIONAL
EQUIPMENT DESIGNED FOR USE IN INDUSTRIAL ENVIRONMENT, WHICH MAY POSE DIFFICULTIES
WHEN GUARANTEEING ELECTROMAGNETIC COMPATIBILITY IN OTHER ENVIRONMENTS DUE TO
GAR CUT (V. INDUSTRIAL). Instructions Manual
PROBABLE CAUSE.

There is not sufficient preflow of air.
The part is being touched with the nozzle in
the cutting process.
The equipment is cold.
Damaged fan or wiring.
COMPRESSED AIR.
TECHNICAL SERVICE.
REGULATIONS
CONDUCTED AND RADIATED DISTURBANCES.
POSSIBLE SOLUTION.
Increase the pressure. Check there is no brake in the
torch or the electrovalves where the air comes out.
Adjust the electronic plate SCP-2 suitably. Increase
Tprf.
Use a guide shoe or separator.
There is no problem, the fan will not start up
automatically when the equipment is at a certain
