Error message
Possible cause
Remedy
Err 20
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
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)
Err 22
Excess temperature in coolant circuit
Coolant temperature exceeded
The temperature of the coolant is too
high
• Check coolant level in the reverse cooler
• Check temperature nominal value on the
cooling unit
Reset error via robot interface (reset error)
Err 23
HF choke excess temperature
High frequency blocking inductor
excess temperature
The excess temperature of the high
frequency blocking inductor has
triggered
• Allow equipment to cool down
• Adjust processing cycle times if
necessary
Reset error via robot interface (reset error)
Err 24
Pilot arc ignition error
Check plasma torch replacement parts
Err 32
