5.1.3.2 Exchanging electrode caps
Fig. 8: Replacement of the electrode
caps
1. Loosen the electrode caps using the electrode cap wrench or an
equivalent tool (Fig. 8).
2. Turn in clockwise direction, otherwise the cone will be loosened.
3. Push new electrode caps onto the electrode head and press into posi-
tion.
NOTE!
A good condition of the electrode caps is important for
good welding results.
Particularly when welding HSS plates and coated
plates, the electrode caps have to be milled or replaced
after 50 welding operations at the latest (milling tool,
see accessory catalogue).
5.1.3.3 Deploying and locking the electrode arm
