Retention Head is recessed approximately 1/16
” - 1/8” (1.5 – 3 mm) into the Air Tube.
Retention Head is centered within the Air Tube. If not centered, straighten the centering
Tabs of the Retention Head if they are bent. Loosen the knurled nuts, center the
Retention Head and retighten the knurled nuts if necessary.
Make sure air vane is properly installed, on the left side when looking from the nozzle
end. It should be locked in place by the retention head base.
For the
“Double Bend” electrodes, the retention head should be installed with one leg
vertical, and the electrodes straddle that leg.
For the
“Single Bend” electrodes, the extra cutout in the center hole of the retention
head should be centered vertically, and the electrodes are mounted in that cutout
between two legs. A tab on the collar of the retention head fits into the channel on the
bottom of the electrode ceramic for alignment. (See figures below.)
