DIREctIONS OF USE (FIG VI)
MIG/MaG MODE:
NOVOMIG feature allows you to adjust the voltage and the wire speed.
Use the SMART table to find the correct settings based on the type of wire, and the thickness of the metal workpiece.
Then based on the recommendation indicated, simply select :
• The voltage (buttons A/ B & min/max for NOVOMIG 140 & 160 ; button A/B for NOVOMIG 170+)
• Wire speed - adjust the regulator (3) to the colour zone indicated.
Examples :
To weld 0.8mm thick steel, use 0.6 mm diameter steel wire (NOVOMIG 140 & 160) :
• 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
To perform the same operation with NOVOMIG 170+ :
• Move button (4) to the « A » position
• Move the regulator (2) to « min » or « max »
• Move the regulator (3) to the zone of lightest colour, and adjust « by sound » if required.
MMa MODE (NOVOMIG 170+ ONlY) :
Connect the electrode holder and earth clamp to the machine, respecting the polarity indicated on the electrode pac-
kaging. Then adjust the position.
Example :
For welding metal 4mm thick :
• Move button (1) to the « MMA » position.
• Adjust the regulator (2) to the zone corresponding with electrode diameter 2.5mm.
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 stan-
dard EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below :
x/60974
@40°C (T
cycle=10min)
X%-max
60%
Note: the running hot tests have been carried out at atmosphere temperature and duty cycle has been deter-
mined 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.
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 main-
tenance 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,
its' after sales service or a qualified person.
- Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
