Programming electrode replacement:
The electrode magazine supplies new electrodes to the robot in an integrated program as
follows:
Each cartridge on the magazine holds new electrode caps and is equipped with an
inductive sensor to identify the presence or absence of a cap or empty magazine that
needs to be refilled (Figure 13).
Figure 13 Position of inductive sensors
Ensure the electrode approach is perpendicular to the electrode cartridge (Figure 14).
Welding guns with inclined electrode holders may need to compensate on the
approach to the new electrode. Attention: incorrect position of electrodes in the
extraction tool may lead to an increase wear or even damage of the machine and
electrode holder or adapter.
The welding gun closing force should not exceed 100 kg when pressing on the new
electrode cap.
Ensure the welding gun is sufficiently opened before leaving the cartridge with the new
electrode cap and it is pulled perpendicular to the cartridge. Diagonal removal of
electrodes can wear out or even damage electrode cartridge.
