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.
• IP21 indicates that the equipment is :
- Protected against access to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protected against vertically falling drops
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.
The coolant should be changed every 12 months to prevent residue from clogging the torch's cooling system. Any leaks or pro-
duct residues found after use, must be treated in an appropriate treatment plant. If possible, the product should be recycled. It is
forbidden to drain the used material into waterways, pits or drainage systems. Diluted fluid should not be emptied into the sewage
system, except where allowed under local regulations.
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 (FIG-1)
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
The equipment is supplied with a 16A plug type CEE7/7 and must only be used on a single-phase electrical installation 230V (50-60 Hz) with 3 wires
including one connected to the earth. 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.
• When the power is turned on, the product starts in standby mode. The device is switched on by pressing the button
• 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 functioning will resume once the power supply is under 265V.
• 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.
