Error messages

Cause

At least one phase of main
supply voltage has failed

Main supply has supplied
over voltage> 480 V

Main supply has supplied
under voltage> 320 V

Welding with water-cooled
torch without water cooling
unit

Electrode operation active
with a TIG torch connected

Through flow monitor
identifies too low a
throughput of coolant

Monitor blocked by dirt

Water-cooling unit is not
available (cable breach in
AUTO mode)

Temperature of coolant >
65°C

Plug between torch-
connection and ground-
socket too large

Connected torch type not
supportet
Analysis of causes can only be carried out by a service technician
Solution

Check main fuse, cables and
connectors

Check mains voltage

Check mains voltage

Connect water-cooling unit

Replace torch (gas-cooled)

for TIG - COOL 1400 or other water-
cooling unit, set special parameter
SP3 to 0 (see chapter 3.13.3)

Remove TIG torch

Switch to TIG operation

Switch off power source immediately

Check whether the CAN connection
cable in plugged in

Check the level of the coolant

Check the connections of the water-
cooled torch

Lift the interruptions in the coolant
circulation

Bleed the coolant circulation system

Check pump

Check whether the CAN connection
cable in plugged in

Connect water-cooling unit

Allow the water-cooling unit to cool
down

Refill coolant

Use smaller torch – hose package or
smaller earth cable

Use other torch type
