5. Safety provisions
 Never use the product if the grinding wheel
is damaged.
 Only use grinding wheels recommended by
MIGATRONIC A/S.
 Only use the product when all parts have
been assembled.
6. Fastening of electrode in the
electrode holder
Place the electrode clamp fitting the diameter of
the tungsten electrode into the electrode holder.
Stick the electrode through the electrode clamp
into the electrode holder.
Tighten the electrode lightly by hand ensuring
that it can still slide in the electrode holder. The
electrode must stick out approx. 2 cm from the
clamp.
Then place the electrode and holder in the
stickout adjustment bolt (10), at the bottom right
hand corner of the front of the machine, until it
stops. Fasten the electrode by slightly turning
the electrode holder to the right.
The electrode clamp has a hexagon which fits
the hole of the stick-out adjustment bolt. Tighten
the electrode so as not to slide in the electrode
clamp. Tightening the electrode too much may
damage the electrode clamp.
An adjusting screw at the back of the stickout
adjustment bolt allows you to adjust the grinding
length. Removing the adjusting screw will
increase the grinding length.
The adjusting screw is factory-set to a grinding
length of approx. 0.3 mm to ensure as many
grindings as possible of the electrode. A
remaining length of 30 mm of the electrode
means that you can re-grind the electrode 450
times.
Usually it is not necessary to break off metal
drops on the electrode. As metal drops do not
fuse with the electrode, they will be removed
during grinding and a new clean tungsten
surface will be achieved which is necessary for
a good ignition of the electrode and a stable
arc.
If a clean tungsten surface is not achieved, you
can re-grind the electrode or make the stickout
length longer.
It is necessary to adjust the stick-out as the
diamond wheel is worn out.

Setting the grinding angle

Set the grinding angle by aligning the logging
scale bush (24) on the electrode guide (22) to
the required degree.
Then lock the electrode guide into position
using the tightening screw (20).
Insert the tungsten electrode into the electrode
holder and lead it through the electrode guide
until it reaches the diamond wheel.
Switch on the machine using the switch (35)
and turn the electrode holder gently and at an
even pace until it meets the electrode guide.
Then remove the electrode holder.
It is not necessary to press the electrode
holder against the diamond wheel; the
weight of the electrode holder provides
sufficient pressure.
To remove the electrode from the electrode
holder, stick the electrode holder into the
stickout adjustment bolt (10) and turn the
stickout adjustment bolt anti-clockwise. Then
pull out the electrode.
