Replacing the window in the cone (axial observation)
1. Move the torch from the working position
downwards.
2. Take the quartz bonnet out of the induction
coil.
Note:
These precautionary measures prevent the
glass parts from becoming damaged during
installation of the cone.
3. Clean the cone with a damp cloth and dry it.
4. Unscrew the cone with the supplied hook
wrench.
Note
:
If the window sticks in the frame, it must be
pushed out from the top. This requires the
deflection mirror of the transfer optics to be
dismantled (see below).
5. Clean the window if necessary.
6. Insert a new or cleaned window into the cone
and fit a sealing ring.
Replace the worn sealing ring.
7. Screw the cone back into the cone opening in
the plasma compartment.
If the window has not been unscrewed with the cone, but remains in the window opening, it
must be pushed down from above. This requires the deflection mirror to be dismantled.
1. Unscrew the two cover retaining screws.
2. Remove the cover and set it aside.
3. Unscrew the 4 screws on the deflection mirror.
