SYNERGIC mode
Press the VOLT.ADJUST key. When the LED of the key is ON, 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 key. When the LED of the key is OFF, it means the INDIVIDUAL mode is
applied.
•
Press the VOLT.ADJUST key. When the LED of the key is OFF, it means the INDIVIDUAL mode is
applied.
•
The welding voltage can be adjusted by the parameter adjustment knob.
6.6.6 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)
TIPS
• 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."
6.6.7 EN ratio
In the AC pulse welding, the EP current (the torch is + polarity) and the EN current (the torch is –
polarity) output alternately, and the heat input to the base metal (penetration) can be controlled
according to the EP and EN ratio. As a result, a high-quality welding can be obtained for very thin plate
or the work which has gap.
For EN ratio setting, select “AC PULSE” or “AC WAVE PULSE” by WELDING METHOD selector key.
When “DC pulse” is selected, EN ratio setting is invalid.
When pressing the EN ratio setting key while the INITIAL CONDITION, MAIN CONDITION, or
CRATER-FILL CONDITION is selected the EN RATIO lamp (located at the upper left on the EN ratio
setting key) lights up, the setting value is displayed in the right display, and the ? LED lamp lights up.
At that condition, it is possible to set EN ratio by using the Parameter adjusting knob. The setting range
is -50 to +50.
Pressing the EN ratio setting key again or pressing the DISPLAY CHANGE key returns to the previous
parameter setting. In addition, it is also possible to change over the display to a current-related
parameter by using the Current setting display selector key and to a voltage-related parameter by using
the Voltage setting display selector key.
The average EN ratio (%) during welding is displayed in the left display.
The standard setting value of EN ratio is 0. As the setting value of the EN ratio is set in the negative
direction, EN ratio becomes smaller (down to -50). As the setting value of the EN ratio is set in the
positive direction, EN ratio becomes larger (up to +50).
