Examples :
To weld 0.8mm thick steel, use 0.6 mm diameter steel wire :
• Move button (1) to the « A » position
• Move button (2) to the « min » position
• Move the regulator (3) to the zone of lightest colour and adjust « by sound » if required
ADVICE AND THERMAL PROTECTION
• Respect the normal rules of welding
• Leave the machine plugged in after welding to allow it to cool
• Thermal Protection : The LED will illuminate. Cooling will take between 10 and 15 minutes depending on the ambient temperature.
DUTY CYCLE & WELDING ENVIRONMENT IN USE
• The welding unit describes an output characteristic of «constant current» type. The duty cycles following the standard EN60974-1 (at 40°C on a
10mn cycle) are indicated in the table here below :
x @40°C (T
cycle=10min)
X%-max
60%
During intensive use (> duty cycle) the thermal protection can activate, if this event the arc switches off and the thermal protection indicator swit-
ches on. The welding machine has a constant current output in MIG/MAG. The welding machine has a constant voltage output in MMA.
Note: the running hot tests have been carried out at atmosphere temperature and duty cycle has been determined at 40°C by simulation.
These are A-class devices. They are designed to be used in an industrial or professional environment. In a different environment, it can be difficult to
ensure electromagnetic compatibility, due to conducted disturbances as well as radiation. From 1st December 2010, the new standard EN 60974-10
will be applicable : Warning: these materials do not comply with IEC 61000-3-12. If they are to be connected to a low-voltage mains supply, it is the
responsibility of the user to ensure they can be connected. If necessary consult the operator of your electrical distribution system.
RISK OF INJURY DUE TO MOVING PARTS
The wire feeders contain moving parts that may catch hand, hair, clothes or tools which can lead to injuries! Take extra care.
• Do not lay a hand to swivel or moving components or parts to the drive!
• Ensure that the housing covers or protective covers remain closed during operation!
MAINTENANCE
- Maintenance should only be carried out by a qualified person.
- Switch the machine off, ensure it 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 connec-
tions 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, its' after sales service or a
qualified person.
- Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
