COOLING UNIT (OPTION)
P 1L/min = 500W
WCU0.5kW_A Capacity = 1.5 L
U1 = 185V - 265V
P 1L/min = 1000W
WCU1kW_A Capacity = 3 L
U1 = 85V - 265V
P 1L/min = 1000W
WCU1kW_B Capacity = 3 L
U1 = 400V +/- 15%
This machine may be connected to a cooling system for the cooling of the water torch. In the OPTION menu, this cooling unit system can be deac-
tivated.
A 3 second press on the «JOB» button allows access to the cooling unit system menu.
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 eyesm 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.

TIG 220 DC / 300 DC
TIG 220 DC
When working within the 185V-265V power supply range, the cooling unit is controlled by the welding
When working within the 85V-185V power supply range, the cooling unit is always switched off.
The cooling unit is controlled by the welding machine throughout the 85V-265V power supply range.
TIG 300 DC
The cooling unit is controlled by the welding machine throughout the power supply range.

SOLUTIONS
Check the internal cabling between the MMI and the
PCB.
Replace the MMI.
Replace the torch.
Replace the pedal and check that the switch is not
stuck.
Check the automaton's cabling.
A power surge is the origin of the message and origi-
nates from a motor overload, lightning...
The installation must be three phase (3P+N+E)
Call your supplier.
Check the connectors between the welding current
source.
Fill the cooling unit's tank.
Check the liquid flow's between the unit and the
torch.
