What does the Inductance/Dig control do on the CC/CV model?

When the Stick (SMAW) mode is selected, the control adjusts Dig — setting it higher increases short-circuit amperage at low arc voltage to assist with arc starts and reduce electrode sticking. When MIG (GMAW) is selected, it adjusts inductance, which controls the wetness of the weld puddle — setting it higher increases puddle fluidity. When pulsed MIG or a TIG process is selected, this control is not functional. (Page 19)
