22. K1BL: AEC (Automatic Electrode Changer)
Electrode holder
One holder is packed with machine as standard. Inside the holder, there is a collet of 1.1mm.
In order to use AEC, extra 17 holders are required.
AEC unit
Electrode guide
One guide for ø0.15mm electrode is supplied as standard.
The guides should be changed depending on electrode diameter.

23. Gripping face of 1.0mm diameter
K1BL Electrode
Gripping face of 1.0mm diameter
Electrode (ø0.08 – 0.25mm)
Normally, electrode of K1BL has gripping face of ø1.0mm as shown above. The gripping face has always diameter of 1.0mm regardless of electrode diameter, which means you can always use the same electrode holder (collet).
Although electrodes without gripping face are also available, they are not recommended due to their unstable cutting performance. When customer requires them, they need collets depending on electrode size
