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:
-
Rectifier input-earth: Ra> 50 Mohms
-
Rectifier output-earth: Ra> 50 Mohms
-
I2 Switch - Rectifier output: 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
PERFORM THE MAINTENANCE OPERATIONS DESCRIBED IN THIS MANUAL.
USE THE SHORTEST WELDING WIRES POSSIBLE AND KEEP THEM PLACED NEXT TO EACH OTHER NEAR
IF THE WELDING PIECE IS GROUNDED, KEEP IN MIND OPERATOR SAFETY AND NATIONAL
GALA MIG 257.
