Stray welding currents/voltages may destroy earth conductors, damage electrical equipment or cause components to warm up which
may cause a fire.
- All welding connections must be firmly secured, check regularly !
- Check that the metal piece fixation is strong and without any electrical problems !
- Attach or hang all the electrically conductive elements,such as the trolley in order to insulate them
- Do not place any electrical equipment such as drills on top of the welding machine without insulating them !
- Always place welding torches or electrodes holders on an insulated surface when they're not in use !
EQUIPMENT INSTALLATION
• Put the machine on the floor (maximum incline of 10°.)
• Ensure the work area has sufficient ventillation for welding, and that there is easy access to the control panel.
• The machine must not be used in an area with conductive metal dusts.
• The machine must be placed in a sheltered area away from rain or direct sunlight.
• The machine protection level is IP21, which means :
- Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protection against vertically falling drops.
The power cables, extensions and welding cables must be fully uncoiled to prevent overheating.
The manufacturer does not incur any responsability regarding damages to both objects and persons that result from an incorrect
and/or dangerous use of the machine.
MAINTENANCE / RECOMMENDATIONS
• Maintenance should only be carried out by a qualified person. Annual maintenance is recommended.
• Ensure the machine is unplugged from the mains, and wait for two minutes before carrying out maintenance work.
DANGER High Voltage and Currents inside the machine.
• Remove the casing 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 cable. If the power cable is damaged, it must be replaced by the
manufacturer, its after sales service or an equally qualified person.
• Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
• Do not use this equipment to thaw pipes, to charge batteries, or to start any engine.
INSTALLATION (FIG-I) – PRODUCT OPERATION
DESCRIPTION
In order to get the maximum from this machine, please read the following instructions:
The Promig is a «synergic» semi-automatic welding unit, for welding (MIG or MAG). It is recommended for welding steel, stainless
steel and aluminium. Adjustment is quick and easy with the « synergic wire speed » function. It works on 3-phase 400V (or on
230V - 3 phase for the DV models as well.)
POWER SUPPLY
The welders are fitted with a 32 A socket type EN 60309-1 which must be connected to a three-phase 400V (50 - 60 Hz) power
supply fitted with four wires and one earthed neutral. The absorbed effective current (I1eff) is displayed on the machine, for optimal
use. Check that the power supply and its protection (fuse and/or circuit breaker) are compatible with the current needed by the
machine. In some countries, it may be necessary to change the plug to allow the use at maximum settings.
Power supply 3-phase 230V for the Promig 400 G DV and 400 DUO DV :
WARNING: these devices are pre-assembled at the factory on 3-phase 400V. If your electrical
installation is on 3-phase 230V amend the connections on the terminal block inside the product.
This operation must be done by a qualified person. Please see the electrical diagram 230V
located inside the product. The power supply must be protected by a 25A circuit breaker and a
30mA differential.
