TIPS
• When the internal function F45 is set to [ON], automatically the setting of "CRATER-FILL
ON" is selected, disabling other welding modes. (The CRATER-FILL key does not work.)
• Setting for current increase and decrease is available for both single-clicking and
doubleclicking.
• Single-clicking or double-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 Crater setting: ON; Initial 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:
– 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 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).
6.7.2.31 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.
