5 Other Smart Reader features

5.1 Cable compensation

Cable compensation enables the welder to adjust the welding voltage measurement in the case
that the welding machine has long intermediate cables, long earth cables, or long torch/gun
cables. The higher the welding current is and the longer and thinner the welding cables are, the
greater resistance occurs in the electrical circuit, leading to voltage loss. The cable compensation
function calculates the actual reduced voltage at the work piece based on the measured value at
the power source and the length and area of cables given by the welder.
To set up cable compensation:
In Smart Reader, select Menu > Settings.
1.
Select Set cable area, and enter the value ∅ x Π (the diameter of the intermediate cables and
2.
earth cables multiplied by pi).
Select Set cable compensation length, and enter the total length of the cables (accuracy of
3.
one meter).
Figure 8: Example of long intermediate cables, total length = 13m

5.2 Real-time WPS monitoring

Smart Reader displays the welding current and voltage while welding, and indicates whether
the values are within the limits of the currently identified WPS. This information is useful for
bystanders observing the welding, and in the case of mechanized welding, for the welding
operator.
