Arc Retry Function

An attachment to the welding start position of a non-conductive material, such as rust, soot, and oil,
may cause an arc start failure during arc start. An arc start failure stops the manipulator and interrupts
work. This is prevented by using the arc retry function.
When an arc start failure occurs () and this arc retry function is performed, the ARCON process is
repeated () according to the retry condition defined in the Arc Auxiliary Condition File. The
manipulator repeats the ARCON procedure as it slightly shifts its position near the arc starting point.
After that, the manipulator returns to the starting point when an arc starts and continues working ().
Arc Start Failure
The Retry Procedure
Returns toward the previous step and performs a
retract inching, then returns to the teaching starting
point and repeats the ARCON procedure.
Successful Arc Start
After a successful arc start, the manipulator
continues to weld.
