The crater fill function operates as follows:
Phase 1
When in 2-stroke control mode, releasing the welding torch trigger switch reduces the wire
feed speed to 84% of its original value. In 4-stroke control mode, crater filling starts when the
trigger switch is pressed for the second time. The optocoupler is activated, supplying a signal
to the power source that crater filling has started, causing the power source to reduce its
output voltage.
Phase 1 continues for a time as determined by the setting of potentiometer 13RP4, up to a
maximum of 1.27 s.
Phase 2
Phase 2 starts when phase 1 finishes. The wire feed unit further reduces the wire speed to
84% of the value during phase 1. The optocoupler turns off, giving the power source a signal
further to reduce the voltage. Phase 2 continues also for a maximum of 1.27 s.
Phase 3 and 4
Phases 3 and 4 are repeats of phases 1 and 2. After phase 4, during which wire feed speed
is 50% of the original value, welding concludes with the preset burn-back time.
If, when in 4-stroke control mode, the welding torch trigger switch is released while crater
filling is in progress, crater filling will be interrupted.
