Error messages (power source)

7.3 Error messages (power source)
A welding machine error is indicated by the collective fault signal lamp (A1) lighting up and an
error code (see table) being displayed in the machine control display. In the event of a machine
error, the power unit shuts down.
The display of possible error numbers depends on the machine version (interfaces/functions).
•
If multiple errors occur, these are displayed in succession.
•
Document machine errors and inform service staff as necessary.

Possible cause
Speedometer error
Wire feeder is not connected
Temperature error
Error in emergency stop circuit
(interface for automated welding)
Overvoltage
Low voltage
Coolant error (with connected cooling
unit only)
Gas error
Secondary overvoltage
PE error
FastStop position
VRD error
Pilot arc current
Cold wire error
Excess current limit of a motor control
card has been triggered
Cold wire error – a permanent deviation
between wire nominal value and actual
value or a blocked drive has been
detected in the process
Plasma gas error
Nominal value significantly different
from actual value -> No plasma gas?
Shielding gas
Nominal value significantly different
from actual value -> No shielding gas?
Remedy
Check wire guide/hose package
•
Switch off cold wire mode in the device
configuration menu (off status)
•
Connect the wire feeder
Allow the machine to cool down
•
Check the external interrupt equipment
•
Check jumper JP 1 on PCB T320/1
Switch off machine and check the mains
voltage
Check coolant level and refill if necessary
Check gas supply
Switch machine off and on again,
inform the service department if the error
continues
Edge 'Acknowledge error' signal (0 to 1) via
robot interface (if available)
Switch the machine off and on again.
If the error persists, inform the service dept.
Check welding torch
Inspect the wire feed system (drives, tube
packages, torch):
•
Check cold wire on the torch / work piece
(moved against work piece?)
•
Check relation of process wire feed
speed to robot travel speed, and correct
if necessary
•
Check wire feed for stiffness with wire
inching function (resolve by checking
wire guides section by section)
Reset error via robot interface (reset error)
•
Check plasma gas supply; use the
plasma gas test function on "cold wire
feed unit" if necessary
•
Check guiding / connections of the gas
supply hose for leaks / kinks
•
Check that the gas supply lead of the
plasma torch is not blocked
Reset error via robot interface (reset error)
