Operating Manual
Page 47 of 73
The power level in the Manual mode is adjusted by turning the Manual potentiometer,
also located on the Interface Unit(see page 58).
When in the Manual mode, the power can be adjusted to between 0% and 100% IGBT
conduction. However if the control is detecting sparks and/or arcs the control will only
increase to the power levels at the point of spark/arc detection.
It is recommended that when operating in the Manual Mode the power level be adjusted
to just below the threshold of sparking. If necessary, us a clamp-on amp meter to check
for current transients (sparking and arcing).
