What is the Dig control and when should I use it on the XMT 304?

The Dig control adjusts short-circuit amperage during Stick (SMAW) welding. When set higher, short-circuit amperage is increased at low arc voltage to assist with arc starts and reduce electrode sticking; when set lower, short-circuit amperage at low arc voltage is the same as normal welding amperage. For Air Carbon Arc (CAC-A) cutting and gouging, place the Mode switch in Stick position and set the Dig control to the maximum position for best results. The Dig control is not functional when a TIG (GTAW) process is selected. (Page 20)
