Loading Settings; Cooling Unit - GYS TIG 220 AC/DC Manual De Usuario

• Connect 5 - automaton mode:
This mode enables to pilot the TIG 220 AC/DC from a console or from an automaton due to 5 pre-saved programs.
For the foot pedal, the «Switch (D)» enables to start or stop welding according to the choosen cycle. The voltage value for the «slider (B)» matches
a program or the actual statut.
This voltage must be between 0 and 5V (step of 0.5V) which is linked to a program reminder:
- Actual status : 0 - 0.5V
- Program 1 : 0.5.- 1V
- Program 2 : 1.0 - 1.5V
- Program 3 : 1.5 - 2V
- Program 4 : 2 - 2.5V
- Program 5 : 2.5 - 3.3V
An additional potentiometer enables to change the current (+/- 15%) either whilst welding or not. The information ARC ON (arc presence) enables
the automaton to synchonise itself (Pull Up 100k entry, automaton side). Put the pin AUTO_DETECT to the earth enables to start the product
without going through the selection window where you can select the type of remote control used.
The 5 loaded settings correspond to the first 5 saved programs (P1 to P5).
The signals' I/O (input/output) are protected at 6.1V.

COOLING UNIT

P 1L/min = 1000W
WCU1kW_A Capacity = 3 L
U1 = 85V - 265V
The cooling unit is automatically detected by the machine. In the OPTION menu, this cooling unit may be deactivated.
Make sure that the cooling unit is turned off before disconnecting the inlet and outlet hoses for torch liquid.
The coolant is harmful and irritates the eyes, the mucus membranes and the skin. Hot liquid may cause burns.
TROUBLESHOOTING
This device integrates a default management system.
A series of messages displayed on the control board allows for a fault and anomalies diagnosis.
ABNORMALITIES
The machine does not deliver any current
and the yellow pictogram signalling thermal
protection is on.
The indicator is on but the product does not
deliver any current.
Voltage error
Despite the filling the tank, the error message
is still on.
Unstable arc
TIG 220 AC/DC
The cooling unit is controlled over the whole voltage range 85V-265V.
CAUSES
The thermal protection has switched on.
The earth clamp or the electrode holder is not
connected to the unit.
The product is protected against overvoltage.
The cooling liquid system is still not working
and the fan is not on.
Fault due to the tungsten electrode
Gas flow too high
SOLUTIONS
Wait the end of the cooling cycle of about 5
min. The pictogram disappears.
Check the connections
An power surge is at the origin of this mes-
sage.
Check the fuse.
Use an electrode size which is more suitable to
the thickness of your metal / workpiece.
Use a tungsten electrode which is properly
handled / prepared.
Reduce the gas flow
