11-7. Error Displays
Ref. 800 687-A
1 Release Trigger Error Display
This appears if the trigger is closed
when the unit power is turned on, or
if the trigger is stuck or defective.
2 No Volt Sensed Error Display
The arc voltage sense circuit is not
receiving feedback. Check voltage
sensing connections. Check con-
nections at 17-position plugs/re-
ceptacles at the unit and welding
power source.
Turn unit off and back on after cor-
recting problem.
If this error continues to occur when
pulse welding, it may help to select
Hot Start.
3 Memory CRC Error Display
The data in the program indicated is
not the same data that was saved.
Perform a system reset.
4 Memory Range Error Display
The data in the program indicated is
out of usable range.
Go through pulse parameters to
make sure they do not exceed set-
tings of the Range display or per-
form a system reset.
5 No Tach Sensed Error Display
The motor tach feedback is not
reaching the control. Check con-
nections.
Press front panel Parameter Select
to clear error.
6 Arc Start Error Display
This appears when pulse welding
and current is detected but the arc
cannot be started. Check and cor-
rect program pulse parameters and
voltage settings. Check voltage
sensing connections.
Press front panel Parameter Select
to clear error.
7 Arc Stop Error Display
This appears when pulse welding
and the motor does not stop at the
end of the weld. If there is high fre-
quency being used in the area, turn
it off. A motor brake circuit problem
can also cause this error.
Press front panel Parameter Select
to clear error.
8 Minimum Gas Flow Error
This appears when gas flow falls
below the minimum CFH set (xx in
example). Adjust gas flow to bring it
above set value.
Press front panel Parameter Select
to clear error.
9 Maximum Gas Flow Error
This appears when gas flow is
above the maximum CFH set (xx in
example). Adjust gas flow to bring it
below set value.
Press front panel Parameter Select
to clear error.
10 Gas Out Of Range Error
This appears when gas flow is
greater than 100 CFH. To protect
the internal sensor, the unit shuts
down until the gas flow can be ad-
justed below 100 CFH.
11 Coolant Flow Error
This appears when coolant flow is
interrupted. Check coolant flow and
coolant supply before continuing
operation.
