switched on or with mains recovery. For safety reasons further operation is carried
out with the hood closed. (3.2).

3.2 Potentiometer R201
3.2.1 Phase angle 1. half wave (TAKT operation)
Potentiometer R201 serves to set the transformer load. At works it is set at
60° el with Thyro-A 1A and at 90° el with Thyro-A 2A.
Transformer loads with a nominal induction > 1.2 T, as well as wound core and toroi-
dal core transformers optimization is necessary. With Thyro-A 1A generally 80°el turn
(to the right), with Thyro-A 2A turn at smaller angles (to the left). An optimal setting is
achieved when the rush current is minimal.
