10. OPERATION (continued)
10.3 Information common to all models
10.3.1 Indication on digital display
Digital displays are designed to indicate the items listed below:
(1) Parameter set values
In the Set Value Indication mode during down period (except result indication period
immediately after welding process) and during welding period, the parameter set value
under adjustment is indicated.
(2) Output current at welding
During welding period, the indication of parameter set value on the digital display is
automatically switched to the indication of average output current which is updated every
0.5 sec. to reflect the latest output condition.
If it is required to change each parameter setting with its set value monitored during
welding, depress the parameter selection key [3] to change the indication mode into the
“Set Value Indication” mode where the parameter indicator LED starts blinking. If no action
is applied for 5 sec. more or less, or when a selectable parameter is back where it started,
the indication mode automatically returns to the “Average Indication” mode.
When the torch switch is depressed, the sequence parameter indicator LEDs will turn ON
sequentially in response to the welding process in operation. When switched to the “Set
Value Indication” mode, the indicator LED of sequence parameter selected with the
parameter selection key [3] will start blinking.
The average display of the output current is possible adjust offset in the range of
r
10A by
Function No.10. Adjustment quantity is added(subtracted) at the all current range. For this
adjustment, gain adjustment which is change adjust amount is not possible.
See Section 10.3.2, “Adjustor Knob” for the parameters that may be adjusted during
welding with the parameter adjusting knob [4].
(3) Result after the end of welding
When the welding is finished, the average output current for the last 1 sec. is indicated for
approx. 20 sec. by blinking (with no consideration given to the output conditions for crater
filler process). This indication may be used for a welding personnel to check the conditions
on which the welding has been completed and to adjust the conditions for better result.
This indication will disappear in 20 sec. or when the next welding starts or any key on the
front panel is depressed.
The indication period may be adjusted in the range between 0 and 60 sec. by selecting
Function No. 9 with Function selection key [10] where the set value will be indicated on the
left digital display with the unit indicator LED for “sec. (sec)” turned ON.
(4) Errors
Any error caused to the machine will be indicated with blinking numeral assigned to each
error type. See Section 11.1, “How to Solve an Error” for further details including error
numbers.
Note:
The mean value of output displayed on the digital meter is processed with
software, which cannot be guaranteed as measuring instrument management
data.
