Minimizes stickiness with XX18, XX14, XX22, XX24, and XX13
electrodes. Also for pipe welding with XX10 and XX18 electrodes
Softer, more slowly responding arc
Starting point for XX10 electrode/open root vertical down joint
Stiffer, more rapidly responding arc
Auto-Crater off (see Section 6-4). More sensitive Auto-Stop
Starting point.
Less sensitive Auto-Stop
