About Power Source Condition File
This is the file where the Power Source characteristics: voltage characteristic, etc., is registered. This
file contains the information for Power Source control.
For precise control of the welding current and voltage, the control signals sent from the controller to the
Power Source must be properly adjusted.
The voltage of the current control signal is called the welding current reference value; the voltage of the
voltage control signal is called the welding voltage reference value. A reference value is in the range
between 0 and 14V (or between 0 and -14 depending on Power Sources).
How the output of the welding current or voltage changes with the reference value depends on the
Power Source model, and this relationship between the reference value and output value is called an
output characteristics. Each Power Source condition data file contains the output values (measured
values) associated with several reference values. The figure below is an example of the welding
current output characteristic curve.
