What does "dig" do when welding using the SMAW Process?

Question

It provides additional amperage when the arc voltage decreases
It provides additional inductance when the current level drops
It provides additional voltage when the arc voltage decreases
It provides additional voltage regardless of arc voltage to assure a "driving" type arc

Answer 1

In the context of Shielded Metal Arc Welding (SMAW), "dig" refers to the characteristic of certain electrode types that allow the welder to increase the arc stability and force the arc to penetrate more effectively into the base material. Specifically, "dig" is used to create a more "driving" arc, which helps control the depth of penetration and improves performance in certain welding situations.

The correct answer to your question is:

It provides additional voltage regardless of arc voltage to assure a "driving" type arc.

This feature is particularly beneficial when welding in out-of-position situations or when dealing with rust or contaminants on the base material.
