6.7.2.30 F49: Current increase and decrease by single-clicking
To increase/decrease the welding current by the torch switch operation, set the current increase/ decrease volume at
single-clicking. This function is available when the internal function F48 (Adjusting current with torch switch) is set to
[ON].
•
Set the current increase/decrease volume by single-clicking in the range of -100 to 100 A.
6.7.2.31 F50: Current increase and decrease by double-clicking
To increase/decrease the welding current by the torch switch operation, set the current increase/ decrease volume at
double-clicking. This function is available when the internal function F48 (Adjusting current with torch switch) is set to
[ON].
•
Set the current increase/decrease volume by double-clicking in the range of -100 to 100 A.
6.7.2.32 F51: Special crater repeat
In the sequence of main welding of the "CRATER-FILL ON (Repeat)" (during start input holding), the torch switch
operation can switch the welding and crater treatment repeatedly as many times as needed.
•
[ON]: Setting of "CRATER-FILL ON (Repeat)" is applied, and transits to the crater treatment by single-clicking of the
torch switch during the welding sequence (start input holding). It is available to return to the main welding as many
times as needed even after transit to the crater treatment by single-clicking of the torch switch.
When this function is enabled, "special crater (repeat)" is displayed in the HOME screen.
•
[OFF]: disables the function.
T I P S
•
When this function is set to [ON], automatically the setting of "CRATER-FILL ON
(Repeat)" is selected, disabling other welding modes. (The CRATER-FILL menu does not
work.)
•
Single-clicking operation should be within 0.3 seconds.
•
At the time of transition to crater, press the torch switch for at least 0.3 seconds.
•
Welding method at crater treatment is the same as that of main welding.
Example:
In the setting examples of Initial welding current: 80 A; Main welding current: 100 A; and Crater current: 60 A, the
following diagram is available:
•
In the following cases, this function cannot be used:
– Internal function F11 (Fine adjustment of welding conditions memory) is set to "1" to "30" (enabled);
– 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
