6.6.8 Penetration control adjustment
This section explains how to adjust the penetration control. Using the constant penetration function enables to
automatically adjust the wire feed speed so that the constant welding current can be assured even when the wire feeding
length changes.

The "Penetration control" icon appears at the top of this screen and the HOME screen while the penetration
control is ON.

To cancel the operation: Select "Penetration control" again to switch to OFF.
NOTE
•
Penetration control can also be set in the PARAMETER > Details screen.
T I P S
• The penetration control is available when "DC" is selected by the WELDING PROCESS menu.
•
The penetration control function is available when "Fe", "Fe (FCW)", "CrNi (FCW)" or "Cr 18"
is selected by the WIRE MATERIALS menu.
• The penetration control functions only during the production weld while it does not during
the initial and crater processes. Also, the function cannot be used in arc spot.
6.6.9 Adjustment of wave frequency
This section explains how to adjust the wave frequency. In wave pulse welding, cyclically accumulating two separate unit
pulse conditions at low frequency enables to obtain continuous weld bead looking like rows of fish scales.
Aluminum welding makes a ripple bead using an overlap method.
It can also make welding easier, even if there is a gap between weld parts, because it performs a crystal miniaturization
by vibrating the molten pool, and the welded part becomes more resistant to cracking.
The wave pulse welding changes the wire feeding speed and unit pulse condition.
When it close to the limiting value of response characteristics of wire feed motor, it makes the feeding amplitude small
automatically.
When the wave frequency is 3 Hz or more, the amplitude of feeding speed becomes small. At 5 Hz or more, it disappears.
In this case, the wire feeding speed becomes stable and only the unit pulse condition changes.
