The arc force control is adjustable from -10 to +10
This adjustment senses voltage and when the electrode length is short (low voltage) the machine will deliver a little extra current (a form of slope control)
for 5p open roots a higher arc force setting will keep the electrode from sticking.
for low-hy a lower arc force setting will reduce spatter.
