This section explains how to adjust the welding voltage. The adjustment of welding voltage can be carried out either by
the SYNERGIC mode or INDIVIDUAL mode.
T I P S
• Some conditions such as synergic condition does not meet the appropriate level if a mixing gas ratio
of shield gas is not the specified value. ( 6.6.1
-
Welding mode setting)
• Even when the base material side/torch side cable or torch cable is extended, adjust to a higher
voltage setting beforehand in consideration of voltage decrease.
• The voltage displayed during the setting or welding is the voltage of output terminal (base metal side)
between the wire feeder and welding power supply.
■ 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.

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)
T I P S
• 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."
