6.7.2.44 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:
6.7.2.45 F67: Setting change of current value (initial condition, crater condition)
When “CRATER ON” is selected, the current value of the initial condition and the crater condition can
be set in percentage based on the current value of the welding condition.
• [ON]: enables the function.
Set the current value of the initial condition with F68, and set the current value of the crater condition with
F69.
• [OFF]: disables the function.
6.7.2.46 F68: Setting of current value (initial condition)
The current value of the initial condition can be set in percentage based on the current value of the
welding condition.
• Setting range of current value (initial condition): 10 % to 300
％
6.7.2.47 F69: Setting of current value (crater condition)
The current value of the crater condition can be set in percentage based on the current value of welding
condition.
• Setting range of current value (crater condition): 10 % to 300 %
6.7.2.48 F77
：
Welding result control function identification numbers
Sets the identification numbers of welding power source when using welding result control function.
The identification number set in this function become the part of file name when backing up the data of
welding result control function. (

• Setting range of identification number: 1 to 999.
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.
