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.)
6.7.2.5
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]
6.7.2.6
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]
6.7.2.7
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 1 second immediately before the completion of welding.
•
Setting range of welding result display time: 0 to 60 [sec]
6.7.2.8
F9: Analog remote control scale
Change the setting of the scale plate of analog remote control when using the optional analog remote control.
•
Scale plate is available separately for 500 A, 350 A, and 200 A. According to the selected scale of analog remote control,
replace the scale plate as necessary. (

•
When using the remote control in a low current region, set the scale plate to 200A.
