Dahen DA300P - External Voltage (0-10 V) Control; External Voltage (0-12 V) Control; Pulse Peak Ratio Adjustment

- 45 -
10. OPERATION (continued)
(5) External voltage (0-12V) control: Function No. 5 ---- X
When used in AUTO mode combined with INVERTER ARGO, selecting [ON] status for this
function allows to use the machine with almost same conditions by slightly adjusting external
control voltage (pulse current and welding current or base current).
As the factory setting of this function is [OFF], select the status [ON] for Function No. 5 to activate
this function.
(6) External voltage (0-10V) control: Function No. 6 ---- X
When used in combination with robot whose maximum control voltage is 10 volts or less, this
function should be utilized.
As the factory setting of this function is [OFF], select the status [ON] for Function No. 6 to activate
this function.
If the status of Function No. 6 is set to [ON], the status of Function No. 5 will be automatically set
to [OFF].

The following chart shows the relationship between external current control voltage and output
current.
< Ext. control voltage 1 (factory setting) >

External control range is 0V(min.)-15V(max.).
< Ext. control voltage 2 (function No.5 is ON) >

External control range is 0V(min.)-12V(max.).
< Ext. control voltage 3 (function No.6 is ON) >

External control range is 0V(min.)-10V(max.).
(7) Pulse peak ratio adjustment: Function No. 7 ---- O
The factory setting is 50%, which may be adjusted by selecting Function No. 7. When selected,
the set value appears on the left digital display with the unit indicator LED for “%” turned ON.
Pulse peak ratio can be adjusted in the range between 5% and 95%.
