SETTING UP THE EQUIPMENT
• Place the welding power source on a floor with a maximum inclination of 10°.
• Provide sufficient space to ventilate the welding power source and access the controls.
• Do not use in an area with conductive metal dust.
• The welding power source should be protected from heavy rain and not exposed to direct sunlight.
• The machine is IP23 rated, meaning:
- the dangerous parts of the machine are protect against entry by objects greater than 12.5 mm and,
- protection against the rain inclined at 60° towards the vertical.
These devices can be used outside in accordance with the IP23 protection index.
The power cables, extensions and welding cables must be fully uncoiled to prevent overheating.
The manufacturer assumes no responsibility for damage to persons or objects caused by improper and dangerous use of this
equipment.
MAINTENANCE / RECOMMENDATIONS
• Maintenance should only be carried out by a qualified person. Annual maintenance is recommended.
• Switch off the power supply by pulling the plug and wait two minutes before working on the equipment.. Inside the macine, the
voltages and currents are high and dangerous.
• Regularly remove the cover and blow out any dust. Take advantage of the opportunity to have the electrical connections checked with an insulated
tool by a qualified professional.
• Regularly check the condition of the power cable. If the power cable is damaged, it must be replaced by the manufacturer, the after sales service
team or an equally qualified person to avoid any danger.
• Leave the welding power source vents free for air intake and outflow.
• Do not use this welding power source for thawing pipes, recharging batteries/storage batteries or starter motors.
INSTALLATION - USING THE PRODUCT
Only experienced personnel, authorised by the manufacturer, may carry out the machine's set-up. During set-up, ensure that the power source is
unplugged from the mains. Series or parallel power source connections are not allowed. It is recommended to use the welding cables supplied with
the unit in order to obtain the optimum product settings.
DESCRIPTION
This machine is a three-phase power source for semi-automatic, software-supported welding (MIG or MAG), coated electrode welding (MMA) and
refractory electrode welding (TIG). The use of a separate wire feeder is required (sold separately).

POWER SWITCH
This machine is fitted with a 32A socket type EN 60309-1 which must only be used on a three-phase 400 V (50-60 Hz) four-wire earthed electrical
installation.
The absorbed effective current (I1eff) is indicated on the device for optimum operating conditions. Check that the power supply and its protection (fuse
and/or circuit breaker) are compatible with the current required to run the machine. In some countries, it may be necessary to change the plug to allow
the use at maximum settings.
• The power source is designed to operate on 400V +/-15%. The unit enters protection mode if the supply voltage
is less than 330Vrms or greater than 490Vrms (a fault code will appear on the display).
• Starting is done by pressing the START/STOP switch (On), and stopping is done by pressing the same switch (Off). Warning! Never switch off the
power supply while the unit is under load.
CONNECTING TO A POWER SOURCE
This equipment can be operated with electric generators provided that the auxiliary power supply meets the following requirements:
- The voltage must be alternating with an RMS value of 400V +/- 15% and a peak voltage of less than 700V.
- The frequency must be between 50 and 60 Hz.
It is vital to check these conditions as many generators produce high voltage peaks that can damage equipment.
