E013 Weld Failed
– Out of
Tolerance
If the unit is configured to compare each weld results (Actual current,
voltage, time, etc) to a given weld 'target', it will display this error when
the last weld is out of the configured tolerance range. Change weld setup
as appropriate, set a new target, or disable this error as necessary.
No
No
Problems (Most Likely to Least Likely)
Requires reconfiguration of weld setup.
Target configuration needs redefined. Configure new target by selecting F32 and holding the Lock
button.
Requires adjustment of tolerance. Adjust tolerance either by using Weld Energy F35 or Drop Time F34.
E017 Pilot Blew
Out
During the pilot arc stage, the gun lifted as expected. The arc voltage
whould be within a window of 12V and 60V (typically 30-40V). This
error is generated if the arc voltage exceeds 60V, representing a
condition where the pilot arc blew out.
No
No
Problem
Debris on the work material.
Check surface conditions and clean the workpiece of any ferrule dust or debris.
E018 Drop Time
is Too Long for
Short Cycle
The Configuration of the drop time (F31) and the front panel time make
it such that the pilot arc supply must be on for more that 40ms. The
Maximum time the pilot arc will stay on is 40ms, so it is possible the
arc will go out before the main arc starts.
No
No
Problem
Requires reconfiguration of drop time and/or front panel time.
E020 Voltage on
Output Studs
A voltage higher than normal appeared on the weld terminals. When
this is used, the capacitors are discharged and the unit must be shut
down.
No
Yes
Problems (Most Likely to Least Likely)
External connections from weld terminals need removed and isolated. Use meter to confirm voltage on
terminals.
If > 42 V for > 1 second, check wiring to chopper modules (gate wires).
Incorrect wiring to chopper modules (gate wires). If damaged/cracked, replace modules and control
board.
Failure of the control board. Replace control board.
E021 Unable to
Charge
The unit is unable to charge.
No
No
Problems (Most Likely to Least Likely)
Fuse F2, Inspect and measure to find reason for the over-current.
Incorrect wiring to bridge, charge IGBT and/or choke. Reconfigure wiring where needed.
Faulty charge IGBT. Replace charge IGBT.
Failure of the control board. Replace control board.
Failure of the power supply board. Replace power supply board.
