Operating problems, causes and remedies
All machines are subject to rigorous production checks and final checks. If despite this, anything fails to
work at any time, please check the machine using the following chart. If none of the fault rectification
procedures described leads to the correct functioning of the machine, please inform your authorised
dealer.

Error messages (power source)
All machines are subject to rigorous production and final checks. If, despite this, anything fails to work at
any time, please check machine using the chart below. If none of the fault rectification procedures
described leads to the correct functioning of the machine, please inform your authorised dealer.
NOTE
A welding machine error is indicated by an error code being displayed (see table) on the
display on the machine control.
In the event of a machine error, the power unit is shut down.
• If multiple errors occur, these are displayed in succession.
• Document machine errors and inform service staff as necessary.
Error message
Possible cause
Remedy
Speedometer error
Check wire guide/tube package
Err 3
Wire feed unit not connected
• Switch off cold wire mode in the device
configuration menu (off status)
• Connect wire feed unit
Temperature error
Allow machine to cool down.
Err 4
Error in emergency stop circuit
(interface for mechanised welding)
• Check the external shut-down equipment
• Check plug-in jumper 1 on PCB T320/1
Err 5
Overvoltage
Err 6
Undervoltage
Switch off the machine and check mains
voltages
Err 7
Coolant error (only if cooling module
connected)
Check coolant level and refill if necessary
Err 8
Gas error
Check gas supply
Err 9
Secondary overvoltage
Err 10
PE error
Switch the machine off and on again.
If the error persists, inform the service dept.
Err 11
FastStop position
Edge "Acknowledge error" signal (0 to 1) via
robot interface (if available)
WARNING
No function of the external shut-down devices (emergency stop switch)!
If the emergency stop circuit has been realised using an external shut-down device via
the interface for mechanised welding, the device must be set for this setup. If this is not
observed, the power source will ignore the external shut-down devices and will not shut
down!
• Disconnect jumper 1 on PCB T320/1 (TETRIX) or M320/1 (PHOENIX)!
