Programming electrode extractor:
The removal of the electrodes is to be programmed as follows:
The electrode to be changed should be positioned to approach the axis of rotation of
the extractor tool and at the same time at right angles to the milling unit (Figure 11).
Welding guns with angled electrode holders must be balanced for a clean and direct
approach to the tool. Caution: incorrect position of the electrodes in the extracting
tool can cause increased wear and tear or even damage to machine and to electrode
holder.
Figure 11 Position of the removal tool
The electrodes are inserted all the way to the upper edge but the removing tool is not
in contact with electrode holder.
The welding guns always remain sufficiently open when changing.
The time to loosen the electrode in the jaws of the extractor is less than one second.
A longer stay in the extraction tool wears the electrode
As the electrode approaches the extractor, the extractor is to run in the opposite
direction of extraction for a minimal number of revolutions to allow entry of the
electrode cap.
