INELCO GRINDERS A/S TRUNCATOR
Inelco Grinders A/S, Industrivej 3, DK-9690 Fjerritslev, Denmark 10
Adjustment of the position on the grinding disc takes place on the eccentric guide (8). This has a locking
ring (9) to fix its position. The 3 positions are indicated by lines on the guide (8). The lines for the position in
question must point vertically upwards. See illustrations below –seen from the front and marked with red
lines:
Position A Position B Position C
The position of the eccentric guide can be placed steplessly between the three marks, which makes is
possible to use more of the grinding disc when truncating diameters below 2 mm.
Note that the two outer positions, A and C can, as a maximum, be used for a truncated diameter of 2
mm.
If a larger truncated diameter (Ø2 mm - 4 mm) is required, the eccentric guide must be positioned midway
between positions A and B, or B and C.
Use of the Truncator
1. Grind an electrode tip on the Ultima-TIG grinder.
2. Loosen the electrode in the stick-out adjustment (1) on
the grinder.
3. Pull out the electrode approx. 20 mm. Insert it into the
stick-out adjustment for the Truncator (2) and secure it.
4. Insert the electrode holder into the truncator (3) without
letting the electrode touch the grinding disc.
5. Start the grinder and push the electrode holder with
moderate force in a rotating movement against the
grinding disc. Pull it a little away when grinding is
complete. Ensure that the electrode holder has turned
a full 360° revolution against the grinding disc.
6. Turn off the grinder and take out the electrode holder
once the grinder has come to a complete stop.
After a large number of grinding operations, the geometry of the tip can change, and it is recommended,
that random checks of the diameter of the tip be made and the Truncator reconfigured as and when
needed.
