Equipment Installation; Maintenance / Recommendations - GYS TIG 220 DC Mode D'emploi

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 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.
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 – PRODUCT OPERATION
Only qualified personnel authorized by the manufacturer should perform the installation of the welding equipment. During set up, the operator must
ensure that the machine is unplugged. Connecting generators in a series or a parallel circuit is forbidden.
HARDWARE DESCRIPTION (FIG-1)
These TIGs are inverter welding power sources for direct current (DC) refractory electrode welding (TIG) and shielded metal arc welding (MMA).
The TIG process requires gas shielding (Argon).
The MMA process can weld any type of electrode: rutile, basic, stainless steel and cast iron.
These TIGs can be equipped with a manual remote control (ref. 045675) or a foot pedal (ref. 045682).
The TIG 300 DC can be equipped with an automatic command (CONNECT-5).

POWER SUPPLY – STARTING UP
• The TIG 300 DC is supplied with a 5-pole (3P+N+PE) 400V 16A three-phase plug of type EN 60309-1 and is supplied from a 400V (50 - 60 Hz)
three-phase electrical installation WITH earth. This equipment must only be used on a three-phase four-wire power system with the neutral connected
to earth. The TIG 220 DC is delivered with a single-phase 3-pole (P+N+PE) 230V 16A CEE17 plug, is equipped with a «Flexible Voltage» system and
is supplied on an electrical installation with earth between 110V and 240V (50 - 60 Hz).
The effective absorbed current (I1eff) is indicated on the welding current source and for the maximum operating conditions. Check that the power
supply and its protection (fuse and/or circuit breaker) are compatible with the current required in use. In some countries, it may be necessary to
change the plug to allow use at maximum conditions. The user must ensure that the plug is accessible.
• The welding current source goes into protection if the supply voltage is less than or greater than 15% of the specified voltage(s) (a fault code will
appear on the keyboard display).
• The TIG 300 DC is switched on by turning the on/off switch (7) to position I, conversely, it is switched off by turning to position O. The TIG 220 DC
is switched on by pressing the standby button. Caution! Never switch off the power supply when the welding current source is under load.
• Fan behaviour: In MMA mode, the fan runs continuously. In TIG mode, the fan runs only during the welding phase and then stops after cooling
• Warning: Increasing the length of the torch or return cables beyond the maximum length specified by the manufacturer will increase the risk of
18
electric shock.
