Transferred arc lost during downslope
- This error occurs when the
arc is lost after a stop signal is received but before the current
downslope completes. It substantially shortens the electrode life and is
typically due to an incorrect lead-out or when cutting a given material
thickness with excessive current. When cutting small pieces that tend
to drop into the table after being cut, there should be a very short lead
out or none at all. On thicker materials, the arc is sometimes lost when
crossing the kerf during the lead out.
It is critical that the lead-outs
be fine tuned so the arc is not lost before downslope is complete.
