GYS TIG 250 AC/DC Mode D'emploi page 21

Do not use the cables or torch to move the welding current source. It must be moved in a vertical position.
Do not move the power source over people or objects.
Never lift a gas cylinder and the power source at the same time. Their transport standards are different.
INSTALLATION
Rules to follow:
• 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 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 or connection cables are damaged, they must be replaced by the
manufacturer, its after sales service or an equally qualified person to prevent danger.
• 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.
• Do not use this welding current/voltage source for thawing pipes, recharging batteries/accumulators or starting motors.
The coolant should be changed every 12 months to avoid deposits that could disrupt the cooling system of the torch. Any leaks
or residues of the product, after use, should be treated in an appropriate purification plant. If possible, the product should be
recycled. Spent fluid must not be emptied into waterways, pits or drainage systems. Diluted fluid should not be emptied into the
sewerage system, unless permitted by local regulations.
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)
The TIG 250 AC/DC is an Inverter welding unit to be used with refractory electrodes (TIG) in direct (DC) or alternative (AC) current.
TIG welding requires gas shield protection of pure gas (Argon).
The MMA process can wel all types of electrodes : rutile, basic, stainless and cast iron.
The TIG 250 AC/DC can be equipped with a remote control (ref. 045675), foot pedal (ref. 045682) or an automatic command (CONNECT-5).
1- Display + incremental buttons
2- Positive Polarity socket
3- Negative polarity socket
4- Torch gas connection
5- Trigger connector
6- Coolant inlet connector
7- Coolant outlet connector
INTERFACE (MMI) (FIG-2)
The control board is made of a colour TFT screen and two potentiometers. It can be operated in 3 different modes:
• Mode 1 or Standby mode: with potentiometer 1 you will be able to set the welding current, and with potentiometer 2 the parameters related to
the welding current.
• Mode 2 ou Welding mode : by pushing potentiometer 1 you will have access to the top menu. Then by turning the button, you may select the
welding mode. You may exit this menu by waiting 8s or by pushing potentiometer 2 -> back to Mode 1.
• Mode 3 ou Settings mode : by pushing potentiometer 2 you will have access to the welding parameters and may select one of them by turning the
potentiometer. You may exit this menu by waiting 8s or by pushing potentiometer 2 -> back to Mode 1.
