6.7.2.27 F45/F46/F47: Special crater sequence (effective/initial standard time setting/
crater standard time setting)
Incorporates initial condition and crater condition in the "No crater" sequence.
•
Setting the internal function F45 to [ON] enables to carry out the initial welding/crater treatment set by
F46/F47 even in the welding of "No crater" condition.
•
When this function is enabled, the LED of "No crater" of the CRATER-FILL key flashes, enabling the
internal functions F46 and F47.
•
To the internal function F46, set the time for initial welding in the range of 0.0 to 10.0 seconds. Set the value
in the range of 0.0 to 10.0 seconds.
•
To the internal function F47, set the crater treatment time in the range of 0.0 to 10.0 seconds. Set the value
in the range of 0.0 to 10.0 seconds.
T I P S
• When the internal function F45 is set to [ON], automatically the setting of "No crater" is
selected, disabling other welding modes. (The CRATER-FILL key does not work.)
• Welding method at crater treatment is the same as that of main welding.
•
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 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 function F29 to F32 (External input terminal setting) is set to "5" (Loading welding
condition).
