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 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.
•
[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 conditions 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 conditions are not registered to the memory;
–
Analog remote control (optional) is not connected to the welding power source;
–
Internal function F44 (Reading welding condition with remote control) is set to "ON" (enabled);
–
Internal function F45 (Special crater sequence) is set to "ON" (enabled);
–
Internal function F48 (Adjusting current with torch switch) is set to "ON" (enabled); or
–
Internal function F51 (Special crater repeat) is set to "ON" (enabled); or
–
Either of the internal functions F29 to F32 (External input terminal setting) is set to either "4" (Start) or
"5" (Loading welding condition).
–
Internal function F4 (Auto/Semi-auto mode) is set to a value other than "0" (Semi-auto mode).
