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. (
-
Operation of Analog Remote Control (Optional))
•
When using the remote control in a low current region, set the scale plate to 200A.
6.7.2.9
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.
6.7.2.10 F11: Fine adjustment of welding JOB 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.
•
[1] to [30]: enables the function. Turning the welding current adjustment knob on the analog remote control enables
to fine adjust the current, and turning the voltage knob enables to fine adjust the voltage.
–
Setting range: 1 to 30 %
–
Turning both of the current and voltage knobs to the center of scales sets the welding JOB to those stored on the
welding condition memory. Adjust the current/voltage with the standard of the center of scales. To increase the
welding current or voltage, turn the knob counterclockwise and to reduce the welding current or voltage, turn
the knob clockwise.
•
In the following cases, this function cannot be used:
–
Welding JOB are not registered to the memory;
–
Analog remote control (optional) is not connected to the welding power source;
