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.
Press the CONSTANT PENETRATION key. When the LED of the key is ON, it means the penetration control is ON.
This results in reduction of changes in penetration depth and bead width of the base material. Especially for welding
where you desire to make penetration depth constant, use the welding power source with this penetration control function
enabled.
