6.7.2.3 F5: Maximum external command voltage
When the internal function F4 (Auto/Semi-auto mode) is used with the setting of "1", set the maximum
value of command voltage input from outside.
Select either from 10 V, 14 V, or 15 V.
The below charts show the relationship between current/voltage command voltage and welding
current/voltage.
(Use these charts as a rough indication. Welding current/voltage against the welding conditions setting
voltage may differ from the indications on the charts depending on the external input (command
voltage), wire length or routing of the cable at base material side/torch side, or wire feeding length
difference.)
6.7.2.4 F6: Upslope time
When the difference between the initial current and welding current is large, the wire may burn up at
the change of the conditions. In this case, adjust the time period changing from the initial current to the
welding current (upslope time) longer.
• Setting range of upslope time: 0.0 to 10.0 [sec]
6.7.2.5 F7: Downslope time
When the difference between the welding current and crater current is large, the wire may plunge into
weld pool at the change of the conditions (the wire is fed by inertia because the speed reduction is too
late). In this case, adjust the time period changing from the welding current to the crater current
(downslope time) longer.
• Setting range of downslope time: 0.0 to 10.0 [sec]
6.7.2.6 F8: Welding result display time
Set the time period for the output current and voltage to be displayed on the left/right digital meters in
a flashing mode after the completion of welding. Set the display time in the flashing mode.
The value of display time is the average value for one second immediately before the completion of
welding.
• Setting range of welding result display time: 0 to 60 [sec]
