Operating manual
Never lift a gas cylinder and the welding machine at the same time. Their transport requirements are different.
Do not carry or transport this welding machine over people or objects.
SETTING UP THE EQUIPMENT
• Place the welding machine on a floor with a maximum slope of 10°.
• Provide a large enough area to ventilate the welding machine and provide access to the controls.
• Do not use in environments with conductive metal dust.
• This welding unit must be protected from heavy rain and not exposed to direct sunlight.
• This equipment is rated as IP21, meaning that it is:
- protected against solid objects with a diameter more than 12.5 mm entering the machine
- protected against vertically falling water droplets
Power-supply cables, extension leads and welding cables must be fully unwound to avoid overheating.
The manufacturer assumes no responsibility for damage caused to persons and objects due to the incorrect or dangerous use
of this equipment.
MAINTENANCE / ADVICE
• Maintenance should only be performed by a qualified person.
• Annual maintenance is recommended.
• Disconnect the power supply by unplugging the plug from the socket and wait two minutes before beginning any work on the
equipment. Inside the machine, the voltages and currents are high and dangerous.
• Regularly remove the machine's protective cover and dust with a compressed-air blower. Take this opportunity to have the electrical connections
checked with an insulated tool by qualified personnel.
• Regularly check the condition of the power cable. If the power cable becomes damaged, it must be replaced by the manufacturer, their after-sales
service team or a similarly qualified person in order to avoid any danger.
• Leave the welding machine's openings free for proper air circulation.
• Do not use this welding unit to thaw pipes, recharge batteries/accumulators or to start engines.
SET-UP - OPERATING THE EQUIPMENT
Only skilled staff, authorised by the manufacturer, may carry out the machine's set-up. During set-up, make sure that the machine's power source is
disconnected from the power-supply network. Series and parallel power-source connections are prohibited. Please use the welding cables supplied
with the device in order to obtain the optimal product settings.
EQUIPMENT DIAGRAM (FIG-1)
This machine is an inverter welding unit designed for tungsten inert gas (TIG) welding, direct current (DC) welding and coated-electrode (MMA) wel-
ding.
The TIG welding process requires gas shielding (argon gas).
The MMA welding process allows any type of electrode to be used for welding: rutile, basic, stainless steel and cast iron.
This equipment can be controlled with a manual remote control (PN: 045675) or with a foot pedal (PN: 045682).

START-UP POWER SUPPLY
• The TIG 300 DC is supplied with a three-phase, five-prong (3P+N+PE) 400 V/16 A EN 60309-1 plug and is powered by a 400 V (50-60 Hz), three-
phase electrical system with an earth connection. This equipment should only be used on a three-phase, four-wire power system with the neutral wire
properly earthed. *
• The PROTIG 221 DC FV is delivered with a single-phase, three-prong (P+N+PE) 230 V/16 A CEE17 plug and is equipped with 'Flexible Voltage'
technology. It is powered by a 1110 - 240 V (50 - 60 Hz) earthed power-supply system.
The effective absorbed current (I1eff) is indicated on the welding machine, as well as the most suitable operating conditions. Check that the power
supply and its protections (fuse and/or circuit breaker) are compatible with the electrical current required. In some countries, changing the plug might
be necessary in order to reach the machine's ideal operating conditions. The user must ensure that the machine's outlets are accessible.
• The welding unit will go into protection mode if the supply voltage is more than 15% lower or higher than the specified voltage (a fault code will appear
on the display screen).
• The TIG 300 DC is started up by turning the on/off switch (7) to position I. Conversely, to turn the machine off, turn the switch back to position O.
• The PROTIG 221 DC FV is switched on by pressing the ON/OFF button
is on charge.
