GAR CUT (V. INDUSTRIAL). Instructions Manual
25
SYMPTOM. ANOMALY.
PROBABLE CAUSE.
POSSIBLE SOLUTION.
Low air flow.
Increase the pressure. Check there is no brake in the
torch or the electrovalves where the air comes out.
There is not sufficient preflow of air.
Adjust the electronic plate SCP-2 suitably. Increase
Tprf.
THERE IS PREMATURE WEAR OF
THE CONSUMABLE ELEMENTS.
The part is being touched with the nozzle in
the cutting process.
Use a guide shoe or separator.
The equipment is cold.
There is no problem, the fan will not start up
automatically when the equipment is at a certain
temperature.
THE FAN DOES NOT START UP
WHEN THE MACHINE IS
CONNECTED.
Damaged fan or wiring.
Replace fan or repair wiring.
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
COMPRESSED AIR.
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
TECHNICAL SERVICE.
PERFORM THE MAINTENANCE OPERATIONS DESCRIBED IN THIS MANUAL.
USE THE SHORTEST WELDING WIRES POSSIBLE AND KEEP THEM PLACED NEXT TO EACH OTHER NEAR THE
FLOOR.
IF THE WELDING PIECE IS GROUNDED, KEEP IN MIND OPERATOR SAFETY AND NATIONAL
REGULATIONS
.
EQUIPMENT DESIGNED FOR USE IN INDUSTRIAL ENVIRONMENT, WHICH MAY POSE DIFFICULTIES
WHEN GUARANTEEING ELECTROMAGNETIC COMPATIBILITY IN OTHER ENVIRONMENTS DUE TO
CONDUCTED AND RADIATED DISTURBANCES.
