11. APPLIED FUNCTION (continued)
7)
E-510 Display
If "E-“ and “510" in the displays blink, it indicates the "Pump error".
As this welding power source connect the OTC water cooling unit.
If CON4 connector 1-2pin is open circuit for error signal comes from OTC water cooling unit, “E-
“ and 510” are displayed. See the manual of OTC water cooling unit and checking for the solution.
8)
E-600 Display
If "E-“ and “600" in the displays blink, it indicates the "Battery low (warning)".
This welding power source uses batteries so that it can hold the welding conditions in memory even
when no operation is carried out for long time. “E-“ and “600” in the displays blink when the
batteries get low. “E-“ and 600” are displayed only when the front panel and the welding power
source are temporarily not in use. To cancel the display of the error , press any key. Even when “E-
“ and “600” appear in the displays, welding can continued to be performed,
but when the batteries
run down, the preset welding condition functions and the settings of functions are all erased.
The last welding conditions before power is applied to the welding machine can not be
stored. Each time power is applied to the equipment, all the parameters are reset to initial
values.
Refer to Section 12.4, “ Replacement of batteries” for details.
9) E-710 Display
If "E-“ and “710" in the displays blink, it indicates the "Lack of phase".
By detecting primary input open phase, the malfunction lamp lights up and “E-710” is displayed by
flashing, and then the welding machine comes to an automatic stop. In this case, check the primary
input voltage for each phase.
10) E-751 Display
If "E-“ and “751" in the displays blink, it indicates the "Secondary side over voltage error".
In case where the secondary-side transistor surge voltage has become abnormally high, for
example since an extension cable was used, the malfunction lamp lights up, and “E-751” is
displayed by flashing, whereby the welding power source comes to an automatic stop. In this case,
take an action therefore in accordance with the description given in 10.1.5 “Notice of using AC TIG
mode”, and then turn the power switch “ON” again.
11) E-9XX Display
If “E-9XX“ in the displays blink, it indicated the “Microcomputer error”.
There could be an error in the built-in microcomputer, Please contact your dealer immediately.
When contacting your dealer, you are required to provide the details of the problem you are facing.
