Question

what does \dig\ do when welding using the smaw process?

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

Explanation:

Define DIG control function

Using the DIG Control knowledge point

• DIG control (arc force) temporarily increases amperage when the arc length shortens and arc voltage drops.
• This prevents the electrode from sticking to the workpiece during SMAW welding.

Answer:

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