Possible cause
Coolant
The flow quantity of the torch coolant
has fallen below the permissible
minimum -> the coolant flow is dirty or
cut off because the tube package has
been unsuitably installed
The flow quantity of the torch coolant
has fallen below the permissible level
Excess temperature in coolant circuit
Coolant temperature exceeded
The temperature of the coolant is too
high
HF choke excess temperature
High frequency blocking inductor
excess temperature
The excess temperature of the high
frequency blocking inductor has
triggered
Pilot arc ignition error
Electronics error (I>0 error)
Electronics error (Uactual error)
Electronics error (A/D channel error)
Electronics error (edge error)
Electronics error (S sign)
Electronics error (temperature error)
---
Electronics error (secondary
overvoltage)
Electronic error (I>0 error)
Ignition error
Arc interruption
Error in emergency stop circuit
(interface for automated welding)
Auxiliary drive error, tacho error
Rectifying faults

Remedy
Check coolant level and refill if necessary
•
Check coolant level in the reverse cooler
•
Check coolant lines for leaks and kinks
•
Check that the coolant inlet and outlet on
the plasma torch is not blocked
Reset error via robot interface (reset error)
•
Check coolant level in the reverse cooler
•
Check temperature nominal value on the
cooling unit
Reset error via robot interface (reset error)
•
Allow equipment to cool down
•
Adjust processing cycle times if
necessary
Reset error via robot interface (reset error)
Check plasma torch replacement parts
Switch the machine off and on again.
If the error persists, inform the service dept.
