8.18 High Frequency Points Gap
Adjustment.
WARNING
The unit will generate a High Voltage
component that can cause extreme personal
harm and test equipment damage.
The H.F. unit is located underneath the heat sink assembly.
Confirm that the points are connected to H.F. Unit correctly
and completely.
Confirm there is no dust or foreign debris between the
space of the H.F. points.
If there are any abnormalities observed with the H.F.
points, replace the H.F. points.
The H.F. points Gap is factory set for an optimal setting
for most welding applications. It is recommended that
the H.F. points Gap setting not be changed. The H.F. points
Gap is factory set at 0.8mm.
If the H.F. points Gap is increased (larger than 0.8mm),
the H.F. voltage increases and the frequency tends to
decrease. If the H.F. points Gap is increased too much,
H.F. will no longer be generated.
If the H.F. points Gap is decreased (smaller than 0.8mm),
the H.F. voltage decreases and the frequency tends to
increase.
