When engaged, the extractor should remove the electrode cap in a forward motion in
minimal revolutions.
The removed electrode cap will remain in the removal tool and will be pushed out with
the release of the next electrode. As a result, the jaws remain spread and allow easier
retraction of the next electrode to be removed.
Ensure the welding gun is sufficiently opened before leaving the extraction.
Remove one electrode cap at a time.
Orientation and grease access:
Extraction of electrode caps in an electrode management system that is horizontally
mounted, follows the same principals as defined earlier but in order to have the
electrode caps fall into the waste container, the approach of the weld gun must always
be in one direction, from above (Figure 12).
The gun should be turned 180 degrees in order to remove the electrode from the
opposite arm to again have the electrode fall from the extractor into the waste
container.
In the vertical orientation there is a grease access hole below the extractor unit that
would typically never require greasing. In the vertical orientation the hole should be
plugged to avoid water access contamination. In the horizontal orientation the plug
must be removed, and the hole should point downwards for drainage.

If both electrodes are released simultaneously, the cooling
water escapes from the welding guns unless there is an
active water drawback system.
