6.7.2.11 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).
6.7.2.12 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 conditions 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 method, the time set in internal
function F14 is deactivate.
6.7.2.13 F16: Slowdown speed adjustment
Slow-down speed is the speed to slowly feed the wire from the time of the machine start to the time of arc start.
The slowdown speed is automatically set to an appropriate speed depending on the welding method and wire diameter;
meanwhile, it can be adjusted through this function if manual setting is preferred.
The setting range is ±39 IPM (±1.0 m/min), yet cannot be adjusted slower than ±16 IPM (0.4 m/min). Based on "0,"
adjusting it to the negative direction lowers the speed, and adjusting it to the positive direction accelerates the speed.
When the starting performance is poor, decrease the slow-down speed to a negative value (which lowers the wire feed
speed).
When the starting performance is not poor, setting the slow-down speed to a positive value (which accelerates the wire
feed speed) can shorten the tact time.
