11 PULSE:
* The button is effective when "PULSE" (9) is set to
"ON".
Specify "CUR. (pulse current)", "WIDTH (pulse
width)" or "FREQ. (frequency)" to set each parame-
ter for pulsed welding.
12 PRE-FLOW:
Sets the time from when the torch is turned ON until
when the output voltage is turned ON (i.e. arc start).
Make sure to set it so that the shield gas covers the
welding area before the start of arc.
13 INITIAL CUR.:
* The button is effective when "CRATER" (8) is set
to "ON" or "REPEAT".
Sets the current value for starting the welding.
14 UP SLOPE:
* The button is effective when "CRATER" (8) is set
to "ON" or "REPEAT".
Sets the time for increasing the welding current
gradually to the set value after the initial current.
15 Welding current:
Sets the welding current.

*1:See section "Settings" for how to display welding volt-
age.
In the case of a welding voltage, indicates the welding
voltage (between output terminals of this product) during
the welding operation not the set value.
When the "mode" selection is set to "welding", the display
lamp of the welding-condition setting button section turns on
according to the set details of the welding-condition selecting
section In other words, the display lamp for sections, to which
welding conditions are required to be set, is turned on.]
The display lamp indicated above (indicated within __) nor-
mally remains turned on. When pressing a button corre-
sponding to the display lamp, which is turned on, that display
lamp starts flashing, the LCD display indicates the name of
that item, and the set-value display indicates a set current
value. (By turning the jog dial at this point, the set value can
be changed.)
Note
Do not turn the jog dial without discretion.
(Doing so may result in the change of the present
set value.)
The above operation also applies to the welding mode. (If the
display lamp is flashing, a set value can be changed even
during the welding operation. When there is no need to do
so, press the jog dial, and the display lamp is turned on.
Then, it becomes impossible to change the set value by
means of the jog dial. Therefore, it serves the prevention of
an operation error.)
16 DOWN SLOPE:
* The button is effective when "CRATER" (8) is set
to "ON" or "REPEAT".
Sets the time for decreasing the welding current
gradually and having the crater current started after
the self-holding is turned off.
ARC SPOT TIME:
* The button is effective when the "MODE" (7) is
set to "SPOT".
Sets arc spot time.
17 CRATER CUR.:
* The button is effective when "CRATER" (8) is set
to "ON" or "REPEAT".
Sets the crater current.
POST-FLOW:
18
Sets a period of time for the shield gas to keep flow-
ing after the output voltage is turned off (i.e. arc
stop).
