6.7.2.48 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:
6.7.2.49 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.
6.7.2.50 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
％
6.7.2.51 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 %
6.7.2.52 F70: Setting of upper limit of analog remote control
Sets the upper limit (the value when the knob is turned clockwise all the way) of the welding current adjustable by the
analog remote control (optional accessory).
If it is difficult to perform fine current adjustment with the knob of the analog remote control when welding in the low
current region, fine current adjustment will be easier if this function is used to lower the upper limit.
•
Setting range of the value:
20 to 400 A (WB-P402L)
20 to 550 A (WB-P502L)

*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.
