THERMAL PROTECTION & DUTY CYCLE
• Thermal protection: the thermal protection indicator
depending on external temperature.
• Leave the machine connected to the power supply after welding in order to let it cool down
• The welding unit describes an output characteristic of "constant current" type. The duty cycles following
the norm EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table below :
Note: The machine's duty cycle has been tested at room temperature (40°C) and have been determined by
simulation.
MAINTENANCE
• Maintenance should be carried out by a qualified person.
• Ensure the machine is unplugged, and that the ventilator inside has stopped before carrying out
maintenance work (DANGER High Voltage and Currents).
• JBDC recommends removing the steel cover 2 or 3 times a year to remove any excess dust. Take this
opportunity to have the electrical connections checked by a qualified person with an insulated tool.
• Regularly check the condition of the power supply cord. If damaged it will need to be replaced by the
manufacturer, it's after sales service or a qualified person.
ADVICE
• Respect welding polarities and currents indicated on the electrode packaging
• Remove the electrode from the electrode holder when not in use.
• Ensure air vents are not covered to allow adequate air circulation.
RECOMMENDATIONS FOR REDUCTION OF ELECTRO-MAGNETIC EMISSIONS
The user is responsible for installing and using the arc welding equipment according to the
manufacturer's instructions. If electromagnetic disturbances are detected, then it is the responsibility
of the user to resolve the situation with the technical assistance of the manufacturer.
Evaluation of the welding area
An assessment of potential electromagnetic problems in the surrounding area should be made before
installing the welding machine:
a) Other wiring, power cables, tephone and communication cables; above, below and adjacent to the
welding machine
b) Radio and television transmitters and receivers;
c) Computers or other electronic equipment;
d) Equipment critical for safety purposes (such as safety checks of industrial equipment);
e) Persons using medical equipment, eg pacemakers and hearing aids;
f) Equipment used for calibration or measurements;
g) The user must ensure that other equipment used in the same area is compatible. This may require
additional safety measures;
h) The time of day when welding or other activities are carried out
i) The size of the area to be used; the structure of the building and any other processes in the area.
The surrounding area may extend beyond the boundaries of the building.
Recommendation for methods to reduce the electro-magnetic emission
a. Mains power supply: the equipment must be connected to the power supply as specified in the Manufacturer's
instructions. If interference occurs, additional precautions such as filtering of the mains supply may be required.
The power cable should be shielded in fixed installations, in metal conduits or similar. The shielding should be
continous for the entire lengh of the cable. It should also be connect to the welding machine with good electrical
contact between the metal conduit and the casing.
b. Welding cables: The welding cables should be kept as short as possible and should be positioned close
together, running at or close to the floor level.
