How does the Arc Control (DIG) function work in Stick mode?
The Arc Control (DIG) knob adjusts the short-circuit current when the arc voltage is low, ranging from 0 to 100. Lower DIG settings are recommended for softer electrodes like E7018, while higher settings are recommended for harder, deeper-penetrating electrodes like E6010. For carbon arc gouging (CAC-A), set Arc Control to maximum for best results. (Pages 32–33)
