7.0 ELECTRODE GEOMETRY & INSTALLATION
(cont’d.)
Fig. 12
Note: Be sure that the electrode mounting hole is free of foreign
matter in order for the electrode to be properly seated against
the electrode-stop roll pin.
7.3 Install the electrode from the rotor I.D. as shown in fig. 13. Tighten the
electrode set screw when the electrode is fully seated against the
electrode-stop roll pin. If the electrode is not fully seated against this
pin, the arc gap between the electrode and the tube will be incorrect.
