Design and function
Configuring the welding machine for mechanical arc fusion welding
5.5.4.3

3-cycle operation

This operating mode differs from non-latched operation in the following ways:
•
Once the third cycle (current) has started, the wire electrode is fed, corresponding to the welding
current, until the welding process ends.
5.5.4.4

Latched mode

This operating mode differs from non-latched operation in the following ways:
•
Wire feeding is started by pressing and releasing (tapping) the BRT 1.
•
By pressing and releasing (tapping) the BRT 1 again, wire feeding will stop. (It is not necessary to
keep the torch trigger pressed. This is especially helpful with long welding seams.)
