Operating instructions with spare parts list ESG Plus 6 Operation
orbitalum tools gmbh
(12.07) MT_ESG Plus_BA_04_790052774_07.doc 11
6 Operation
6.1 Switching on the ESG Plus
1. Connect the ESG Plus (consider main voltage).
2. Press the ON/OFF switch (1).
The ESG Plus starts.
6.2 Grinding the electrodes
Hot dust!
Danger of injury to eyes!
: Do not use thorium-coated tungsten electrodes without a suitable suction
devices or a suitable breathing mask.
X Only work with safety goggles.
X Always wear a breather mask.
Do not exert too much pressure on the grinding wheel, since otherwise the
service life of the diamond wheel is shortened.
The strength of the contact pressure, but even rotation of the electrode around
its own axle and a small contact pressure of the electrode to the grinding
produce a high sharpening achievement.
Use a rough diamond wheel during larger sharpening achievement.

6.2.1 Combination of grinding angle and electrode diameter
15° 18°
22,5° 30°
6.2.2 Sharpening electrodes
1. Insert the electrode with the corresponding hole diameter and the desired
angle until the grinding wheel is touched.
2. The electrode tip is sharpened evenly by turning the electrode slowly.
Slow and even rotating motion results in a good and exact sharpening result
(longitudinal grind). If the electrode is not turned, then it is flat ground to the
selected angle.

6.2.3 Surface-grinding the electrode tip
Precision ground point. Although able to grind flat land on tip.
X Insert the electrode (1.0 / 1.6 / 2.0 / 2.4 / 3.2 or 4.0 mm) through the
openings at the front end onto the grinding wheel and square the electrode
tip.
6.2.4 Cutting the electrodes to length
In order for the electrode rods to be used for e.g. orbital welding, or for manual
welding, they have to be cut to length.
1. Insert the electrode into the lateral slot.
2. The electrode is cut evenly by turning the electrode slowly (optional cutting
device for 12, 13, 15 and 17 mm, see chapter 2.2.2, p. 6).
6.3 Switching off the ESG Plus
X Press the ON/OFF switch (1).
The ESG Plus stops.

6.4 Replacing grinding wheels
Danger to injury to hands though unintentional activation of the ESG Plus!
: Do not switch on the ESG Plus while changing the grinding wheel.
