7. Make sure that the drive cou pling is not bent and that the shafts it con nects are in line with each other.
Then in stall and tighten the gun’s mount ing screws. The gun’s mount ing straps must make tight,
solid con tact with the source tray, pro vid ing a se cure path to ground for the high-volt age cur rent that
will pass through the gun.
Pro ce dure 3: In stall the Air/Wa ter Feedthrough and the Air/Wa ter Sup ply/Re turn Lines
There are two main choices when in stall ing the Air and Wa ter feedthrough(s). One feedthrough can be used
that con tains both the three air lines and the two wa ter lines. A sec ond op tion is to use two sep a rate
feedthroughs, one for the three air lines and an other for the two wa ter lines.
If this source is be ing in stalled as a re place ment for an ex ist ing tur ret source and it is pos si ble to re-bend the
ex ist ing wa ter lines to fit the new source, less work would be re quired to use the ex ist ing wa ter feedthrough.
A sec ond feedthrough would then be in stalled in a sep a rate hole for use with the air lines. An un used hole in a
suit able lo ca tion would be re quired for the sec ond feedthrough.
If this is a new in stal la tion or the ex ist ing wa ter feedthrough will not work with the new source then ei ther a
com bi na tion air/wa ter feedthrough or two sep a rate feedthroughs could be used. The com bi na tion air/wa ter
feedthrough will take up less space and only re quires a sin gle feedthrough hole.
1. Be fore in stall ing a feedthrough for fit ting up and fab ri cat ing the lines, it is best to re move the o-ring
so the feedthrough sits flush to the mount ing sur face.
2. Put a feedthrough in place in the source tray, but do not in stall its mount ing nut.
3. Check to see whether the tub ing on the in-vac uum side of the wa ter feedthrough is long enough to
reach the threaded un ions on the gun’s wa ter lines and the air lines are long enough to reach the air
cyl in der ports at the base of the gun. If it ap pears that these air and wa ter lines will be long enough af -
ter all the nec es sary bends have been made, skip this step and pro ceed to step 4. If not, you will have
to splice on an ad di tional length of 1/8” or 3/8" OD tub ing. The ma te rial for these ex ten sions is
type-304 stain less steel tub ing. Add stain less steel ex ten sions by TIG weld ing, us ing suit able sock -
ets or un ions over the joints. Do all weld ing out side the vac uum cham ber, and re move the O-ring
from the air/wa ter feedthrough be fore ap ply ing any heat. In ad di tion, make sure that all sur faces to
be joined are bright clean be fore join ing them. Use ab ra sives as needed to ob tain the ap pro pri ate fin -
ish.
4. Re in stall the air/wa ter feedthrough in the source tray, with its mount ing nut in stalled but only fin ger
tight. Do not re place the O-ring yet.
5. The source should have ar rived with the con nect ing nuts screwed onto the wa ter in take and out let
lines on the rear of the source. Un screw the con nect ing nuts and re move the tub ing nip ples in side.
6. Make the bends re quired to make the in-vac uum tub ing reach the threaded un ions on the gun’s
air/wa ter lines. The bends should be such that there is no ten sion on the tub ing when all con nec tions
have been made, and no bend should be closer than ½" to ei ther end of the in-vac uum tub ing. A fi nal
right-an gle bend should turn each length of tub ing hor i zon tal, with its end just touch ing the junc tion
to which it is to be con nected.
7. When you have made all the re quired bends, re move the feedthrough-tub ing as sem bly from the vac -
uum cham ber.
8. Find the con nect ing nuts and the tub ing nip ples you re moved in step 6.
9. Fit the con nect ing nuts over the ends of the feedthrough’s in-vac uum tub ing, mak ing sure that the
threaded end faces the end of the tub ing.
