EN
GAS COUPLING
- Connect a pressure regulator to the gas bottle. Connect the welding machine using the pipes supplied, and place the two clamps to avoid lea-
kages.
- Set the gas ow by adjusting the dial located on the pressure regulator.
NB : to help facilitate the adjustment of the gas ow, operate the drive rollers by pressing the trigger of the torch (ensure that the drive roller is
completely loose so the wire is not fed through).
This procedure does not apply to «Gasless» welding mode.

DIRECTIONS OF USE (FIG VI)
MIG/MAG MODE:
SMARTMIG feature allows you to adjust the voltage and the wire speed.
Use the SMART table to nd 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 SMARTMIG 142, 152 & 162 ; button A/B for SMARTMIG 3P)
• 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 (SMARTMIG 142, 152 & 162) :
• 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 SMARTMIG 3P :
• 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 (SMARTMIG 3P ONLY) :
Connect the electrode holder and earth clamp to the machine, respecting the polarity indicated on the electrode packaging. Then adjust the posi-
tion.
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 standard EN60974-1 (at 40°C on a
10mn cycle) are indicated in the table here below :

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 difcult 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.
