■
SYNERGIC mode
Press the VOLT. ADJUST menu. When the SYNERGIC is selected, it means the SYNERGIC mode is applied.
•
The welding voltage is automatically set to the values corresponding to the welding current.
•
The voltage value automatically set can be finely adjusted by the parameter adjustment knob. (Welding voltage on the
positive side: high, negative side: low.)
■
INDIVIDUAL mode
Press the VOLT. ADJUST menu. When the INDIVIDUAL is selected, it means the INDIVIDUAL mode is applied.
•
The welding voltage can be adjusted by the parameter adjustment knob.
6.6.7
Arc characteristics adjustment
This section explains the adjustment procedure of arc characteristics (arc status). Using this function enables to adjust the
arc status into soft or hard condition.
Press the ARC CONTROL key. When the LED of the key is ON, it means the arc control is ON.
The setting value is displayed on the right digital meter, and can be adjusted by the parameter adjustment knob. (Positive
value: soft arc condition, negative value: hard arc condition)

•
It is likely that good weld can be obtained by adjusting it to "hard" in low current region and
"soft" in high current region.
•
When using an extended cable for the base material side /torch side or using an extended
torch cable, it is likely that good welding can be performed by adjusting it to "hard."
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.
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.
T I P S
•
The penetration control is available when "DC" is selected by the "WELDING METHOD" menu.
•
The penetration control function is available when "MILD STEEL SOLID", "MILD STEEL
CORED", "STAINLESS STEEL SOLID" or "STAINLESS STEEL CORED" 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.
