6.7.2.7 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]
6.7.2.8 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]
6.7.2.9 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. (

(Optional))
• When using the remote control in a low current region, set the scale plate to 200A.
6.7.2.10 F10: Motor overcurrent detection level
Set the over current detection level for the current flowing to the wire feed motor.
If contact resistance of the wire feeding line section increases due to liner wear / tip defect, etc., motor
current increases (when the feeding roller does not slip). Monitoring this motor current enables to
identify faults of the feeding line.
Set the detection level in the range of 20 to 150 % of the motor rated current.
• The factory default setting is 70 % of 2.8 A (continuous).
If the current flows to the motor exceed the set value, the alarm display of “E-820” is displayed; output of
the welding power source is not stopped.
• According to the use environment such as wires and torches and the customer’s judgment criteria, adjust
the detection level at your discretion.
6.7.2.11 F11: Fine adjustment of welding conditions memory
When the analog remote control (optionally available) is used, fine adjustment of the welding current
and welding voltage of welding condition stored on the welding condition memory is available. This
function is effective when the internal function F4 (Auto/Semi-auto mode) is set to "0".
• [OFF]: disables the function.
