6.7.2.40 F63: Fine adjustment of L pulse peak current
This function allows fine adjustment of the standard pulse peak current at LOW side in the pulse condition of the wave
pulse welding; by setting the adjustment value, finely adjusted pulse peak current at LOW side can be obtained.
Set the adjustment value in the range of -150 to 150 A.

6.7.2.41 F64: Fine adjustment of L pulse peak time
This function allows fine adjustment of the standard pulse peak time at LOW side in the pulse condition of the wave pulse
welding; by setting the adjustment value, finely adjusted pulse peak time at LOW side can be obtained.
Set the adjustment value in the range of -1.5 to 1.5 ms.

This function allows fine adjustment of the standard pulse base current at LOW side in the pulse condition of the wave
pulse welding; by setting the adjustment value, finely adjusted pulse base current at LOW side can be obtained.
Set the adjustment value in the range of -60 to 60 A.

6.7.2.43 F66: Adjustment of feed amplitude ratio
This function sets the feed amplitude ratio of wire (amplitude change of wire feed speed) in the wave pulse welding.
When the wave frequency is under 5 Hz, the wire feed speed is adjusted. By fine adjusting the amplitude of this feed speed,
optimized welding result for the specific purpose can be obtained.
Set the adjustment value in the range from 0 to 100%, with 50% as the standard value.
The relationship between the set value and the welding result is shown in the below table:
Parameter
0% (Minimum value)
100% (Maximum value)
Changes to wire feed
None (constant speed)
Twice the standard speed
Changes in arc

Changes in ripple bead

*1: Mild steel or stainless may have no change from the status of 50% (standard) even with the adjustment of 100%, since the
molten metal flows away before getting solidified.
