–
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 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).
6.7.2.11 F12: Operation time of water-cooled pump
Sets the operation time of water-cooled pump after welding ends.
When the water-cooled welding torch is used, the water-cooled pump operates to cool the welding torch as the welding
ends. The operation time of water-cooled pump at this time can be set:
•
Setting range of water-cooled pump operation time: 20 to 60 min.
•
"ON": Water-cooled pump is always ON
6.7.2.12 F13: Turbo start
The welding power source has the turbo start function using capacitor discharge in order to obtain smooth welding start.
•
[ON]: enables the function.
•
[OFF]: disables the function.
T I P S
• If wire burning is too strong at the welding start, set this function to [OFF] to disable the turbo start
function (disables the function).
6.7.2.13 F14/F15: Start control (time/current) adjustment
Set the time and current for start control to be performed at the time of welding start.
Depending on the welding JOB and set current value, the appropriate time and current for start control are determined; if
proper burning of the wire does not occur at the time of start, adjust the time and current for start control.
For more intense burning, increase the time and current.
For less intense burning, reduce the time and current.
•
Set the time from -50 to 50 % through F14 (Start control time adjustment).
•
Set the current in the range from -100 to 100 A through F15 (Start control current adjustment).
T I P S
• When DC pulse or DC Wave Pulse is selected as welding process, the time set in internal function F14
is deactivate.
