Cleaning the plasma control fiber-optics

Warning! Risk of injury!



Isopropyl alcohol vapors are dangerous to health. Vapor/air mixtures that
represent a fire and explosion hazard may also form.



Observe the corresponding information on hazardous materials.



Ensure appropriate precautionary measures are taken when using
isopropyl alcohol. Always wait for the isopropyl alcohol to evaporate
before switching on the plasma.



The Plasma torch and load coil may be very hot.



Let the components cool for 10 to 15 minutes before commencing work
on them.

Follow the steps below to clean the fiber optics:

Loosen the grub screw on the
fiber optics holder.

Pull the fiber optics out of its
holder.

Fig. 13

Clean the surface of the fiber optics with a cotton cloth.



Before cleaning, dip the cotton cloth in diluted hydrochloric acid (1:10).

Hazardous substance!



Observe the corresponding information on hazardous materials.

Repeat this procedure with distilled water and isopropyl alcohol.

If the fiber optics is heavily soiled, clean it using wet grinding paper (1200 grit)
and then polish it with wet grinding paper (4000 grit).



Cleaning of the plasma control fiber optics is now complete.
