SETTING THE GRINDING ANGLE
FOR GRINDING ANGLES UP TO 25° (50° included angle)
Set the clear plastic "T" on the face of the machine to the desired position by placing the right hand
side of the vertical "T" piece #32 (Fig. 1) at the required grinding angle, tighten the retaining nut.
Insert the electrode into the collet in the electrode holder #22 (Fig. 1). Do not tighten.
Insert the electrode holder into position "B" of the console #24 (Fig. 1) as shown in Fig. 3. Push
the electrode holder in as far as it will go, ensuring the electrode contacts the Plastic "T" piece #32
at the desired angle. Tighten the electrode in the electrode holder by turning the knurled brass
end of the electrode holder.
FOR GRINDING ANGLES GREATER THAN 25° (50° + INCLUDED ANGLE)
Requires the optional 1" [25.4mm] long brass bushing #33 (Fig. 2)
The plastic T piece is not used for this operation. Loosen nut and move the plastic "T" piece all the
way to the left. Re-tighten the retaining nut.
Insert electrode in the electrode holder collet #22 (Fig. 1) . Do not tighten. Slide the 1" (25.4mm)
brass bushing onto the electrode holder until it stops against the shoulder of the electrode holder.
Insert the electrode holder with the bushing and electrode into position "B" shown in Fig. 3. Push it
in as far as it will go. With the electrode loose in the electrode holder, set the end of the electrode
in line with the desired grind angle and tighten the electrode holder by twisting the knurled brass
end of the electrode holder.
SETTING THE GRINDING POSITION
The degree scale on the front of the grinder coincides with the grinding wheel in the grinding
chamber. The bottom of the tungsten electrode must be set to align with the edge of the degree
scale where it registers the desired grinding angle.
Alignment is set by changing the height of the console #24 (Fig. 1) with the regulating screw #20.
