User manual
EQUIPMENT INSTALLATION
• Place the machine on the floor (maximum slope of 10°).
• Provide an adequate area to ventilate the machine and access the controls.
• This equipment must be used and stored in a place protected from dust, acid, gas or any other corrosive substance.
• The machine must be placed in a sheltered area away from rain or direct sunlight.
• The machine protection level is IP23, which means :
- Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protection against the rain inclined at 60° towards the vertical.
These devices can be used outside in accordance with the IP23 protection index.
Power cables, extension leads and welding cables must be fully uncoiled to prevent overheating.
The manufacturer does not accept any liability in relation to damages caused to objects or harm caused to persons as the result
of incorrect and/or dangerous use of the machine.
MAINTENANCE / RECOMMENDATIONS
• Maintenance should only be carried out by a qualified person. A yearly maintenance is recommended.
• Ensure the machine is unplugged from the mains, and then wait 2 minutes before carrying out maintenance work. Inside,
voltages and currents are high and dangerous.
• Remove the casing regularly and any excess of 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 to prevent danger.
• Ensure the vents 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 – PRODUCT OPERATION
Only qualified personnel authorised by the manufacturer should perform the installation of the welding equipment. During the installation, the operator
must ensure that the machine is disconnected from the mains. Connecting generators in series or in parallel is forbidden. It is recommended to use
the welding cables supplied with the unit in order to obtain the optimum product settings.
EQUIPMENT DESCRIPTION (I)
This welding machine is an inverter welding unit designed for use on refractory electrodes (TIG) in direct current (DC) and electrode welding (MMA).
TIG welding requires gas shield protection of pure gas (Argon).
The MMA process can be used to weld any type of electrodes: rutile, basic, stainless steel and cast iron.

POWER SWITCH
• This machine is fitted with a 16 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 indicated on the machine, for optimal use. Check that the power supply and
protection (fuse and/or circuit breaker) are compatible with the current required by the machine. In some countries, it may be necessary to change the
plug to allow the use at maximum settings.
• This machine is started up by turning the on/off switch to position I. Conversely, to turn the machine off, turn the switch back to position O.
• This machine will enter a protection mode if the supply voltage is higher or lower than 15% of the specified voltage(s) (a fault code will appear on the
keypad display). Normal operation resumes as soon as the supply voltage returns to its nominal range.
• Fan behaviour: In MMA mode, the fan works continuously. In TIG mode, the fan works only when welding, then stops after cooling.
• The arc priming and stabilisation device is designed for manual and mechanically guided operation.
CONNECTION TO A GENERATOR
This equipment may operate with generators provided that the auxiliary power meets the following requirements:
- The voltage must be alternating, adjusted as specified and with a peak voltage of less than 700 V,
- The frequency must be between 50 and 60 Hz.
It is imperative to check these requirements as many generators generate high voltage peaks that can damage the machine.
