3. Mounting on the Ultima-Tig/Ultima-Tig-Cut
The original tightening screw and the stretching screw on the Ultima-Tig/-Cut
must be removed, which can only be done when the angle adjustment is in 90°
position. Otherwise it will fall down inside the grinding chamber.
The included stretching screw (Item No. 44550022) must be mounted in the angle
adjustment unit, using a little bit of white grease on the thread, and firmly
tightened with a 14 mm wrench. The included tightening screw (Item No.
75550019) is mounted loosely on the stretching screw. Then the desired grinding
angle is chosen and the tightening screw is tightened firmly by hand.
The AutoGrind grinding module can now be mounted on the tightening screw,
and secured by tightening the hexagon screw (x). Tool is included.
We recommend to position the grinding module, so that the cable from the
grinding module is hanging down to the right as shown on the front page picture
of this manual.
4. Setting the grinding angle
By turning the grinding module counter clockwise, the angle adjustment is loosened and the angle can be
adjusted. By turning the grinding module clockwise, the angle adjustment is tightened again.
5. Connecting AutoGrind and the grinder
The cable from the grinding module is connected to the control box.
The included short cable is connecting the grinder with the control box, so
that the mail IEC plug is plugged in the control box and the female plug is
connected to the male plug from the mains cable on the grinder

The included long power cable is connecting the control box to the main power.
IMPORTANT: Only Ultima-Tig and Ultima-Tig-Cut, that is suitable for the voltage and frequency, as the
control box is connected to, shall be connected to the control box.
If the on/off switch on the Ultima-Tig/-Cut grinder is set to ”on”, the grinder is not running, but will start
and stop by activating the on/off button on the side of the AutoGrind module. The control box
automatically supplies the power to the grinder, when the grinding module is turned on. Therefore the
on/off switch on the grinder needs to be ”on”. Otherwise the control box cannot start and stop the
grinder automatically.
6. Inserting the electrode holder in the AutoGrind
The Electrode is inserted into the electrode holder and securely fastened.
Set the stick-out on the Ultima-Tig/-Cut, as described in step #6 in the
operations manual.
When the electrode holder is inserted in to the AutoGrind module, the
locking pin (black knob) needs to be pressed down to lock the drive unit
and prevent it from rotating.
The electrode holder should be rotated with a light pressure until the
electrode holder locks into the drive unit, you will feel a slight click as the
electrode holder is in position. Next push the electrode holder in and
rotate counter-clockwise until the bayonet lock is holding the electrode
holder in place.
Important: The locking pin must not be held down, when the AutoGrind is started or pressed down
during grinding. This will destroy the inner parts of the module!
7. The automatic grinding program
The control box is programmed to run through the following grinding
process that starts when the on/off button is activated:
i. Ultima-Tig/-Cut grinder is activated and starts to rotate the grinding
disc.
ii. 2 sec. later the AutoGrind module starts to rotate the electrode
holder slowly in 3 sec. This moves the electrode holder towards the
grinding disc, and the grinding of the electrode starts.
iii. The AutoGrind module is then rotating faster for 15 sec. (the grinding time). The grinding time can
be adjusted as necessary (see step #8)

iv. Next, the AutoGrind module slows down for 3 sec. This finishes the grinding, and gives the
electrode tip a fine and consistent surface.
v. The AutoGrind module now shifts rotational direction for 2½ sec. to move the electrode holder
back to the start position. At the same time the grinder is stopped, and the grinding is finished.
The electrode holder can now be turned clockwise and pulled out of the bayonet lock and the grinding
module.
If the on/off button on the grinding module is activated during the grinding process, the program jumps
to #v and the grinder stops.
8. Setting the grinding time
When the controlbox is plugged in to the power source, the
display will show “Ed” (Edition) and the edition number of
the software “1.0” or higher, followed by the preset grinding
time (standard 15 sec.)
The grinding time (see section #7, iii) can be adjusted from 1 to 99 sec. The adjustment is done by
pressing the “+” and “-“ buttons on the front of the controlbox. Each push changes the grinding time with
1 sec.
Any change of the grinding time is only saved in the controlbox after the AutoGrind has completed a
grinding cycle. The grinding time is not saved if the grinding cycle is interrupted.
Display the number of grindings
If the on/off button is pressed while the controlbox is connected to the power source, then
the display will show “8.8” followed by “- -“ and the number of grindings the controlbox has
carried out. The number of grindings is shown two digits at a time. The highest number it
can show is 999.999.
If the power is disponnected for 5 sec. the
controlbox returns to the grinding program.
9. Important when using the AutoGrind on Ultima-Tig-Cut
If the AutoGrind is being used with the Ultima-Tig-Cut, it is necessary to
adjust the electrode guide on the Ultima-Tig-Cut, app. 2mm outwards,
because the electrode holder for the AutoGrind is different than the
standard electrode holder. Otherwise there is a risk that the cutting disc
will cut through the electrode clamp and damage it.

10. Maintenance
The AutoGrind module and control box are maintenance free, but needs to be kept dry and clean.
The rotating part in the AutoGrind module is running in two bearings. If dirt and moisture is getting in to
the bearings, they will not last so long, and it will affect the grinding result.
When the two bearings are worn out, they need to be changed, please contact the distributor where you
purchased the AutoGrind or contact Inelco Grinders.
11. Technical data
The control box is universal and can be plugged in to all one phase power supplies from 100 V to 240 V for
both 50 Hz and 60 Hz.
The grinding module has a 12V motor, that may only be connected to the control box.
