•Focus the direct image with the collector (46.6).

•Use the adjusting buttons to pivot the arc’s mirror image on the rear side of the lamp housing (46.2,46.4) to the side or completely out of the beam path. The arc’s focused im- age remains visible (Fig. 53).

•Use the adjusting buttons (46.1 and 5) to place the direct arc image in the middle of the centering plane, whereby the bright tip of the arc, the focal spot, should lie slightly outside the center (Fig. 54).

•Then pivot the arc’s mirror image with the ad- justing knobs (46.2) and (46.4) and focus it us- ing the reflector (46.3).

•Use the adjusting knobs (46.2 and 4) to orient the mirror image symmetrically to the direct image (Fig. 55).

The V-shaped irradiation of the direct image and mirror image arcs can be superimposed.

Caution:

Fig. 53 Direct arc image focused but not centered (in reality, the image is less focused)

Fig. 54 Direct arc image in target position (in reality, the image is less focused)

The bright tips of the arcs, the focal spots, must never be projected onto each other, as this re- sults in a danger of explosion by overheating.
