6.7.2.44 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.

6.7.2.45 F65: Fine adjustment of L base current
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.

6.7.2.46 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 Decreased Increased
Changes in ripple bead Smooth/Small Distinct/Large (*1)
Reduction of blow hole Less effective Effective
Applied travel speed Low to high Low
Gap allowance Slightly small Slightly large
*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.
