elding Condition
Example:
In the setting examples of Crater setting: ON; Start condition: OFF; Welding current: 100 A; Crater current: 60 A; F48: "ON";
F49:"-10"; and F50: "20", the following diagram is available:
•
In the following cases, this function cannot be used:
–
An analog remote control (optional) is connected.
–
Internal function F11 (Fine adjustment of welding JOB memory) is set to "1" to "30" (enabled);
–
Internal function F44 (Reading welding JOB with remote control) is set to "ON" (enabled);
–
Internal function F45 (Special 2T) is set to "ON" (enabled);
–
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).
6.7.2.34 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.
6.7.2.35 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.
6.7.2.36 F51: Special crater repeat
In the sequence of main welding of the "4T/Crater 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 "4T/Crater 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.
