•
BRT 1 Release .
•
The welding current ramps up to the main current AMP in the selected up-slope time.
First cycle (wire)
•
Press torch trigger 2 (BRT 2).
Wire electrode is fed.
Second cycle (wire)
•
BRT 2 Release .
Wire electrode feeding is stopped, wire electrode is returned by the set wire return value.
Third cycle (current)
•
BRT 1 Press .
•
The main current is reduced in the selected down-slope time.
