Question

dig control only comes into the welding circuit when load voltage is below:

11 volts
24 volts
20 volts
120 volts

Explanation:

Understand DIG control function

Using the DIG Control knowledge point
DIG control (also known as arc force control) is used in Shielded Metal Arc Welding (SMAW/Stick) to prevent the electrode from sticking to the workpiece. When the arc length becomes very short, the voltage drops.

Identify the activation voltage threshold

Using the DIG Control knowledge point
When the load voltage drops below 20 volts, the DIG control circuit automatically increases the welding current (amperage) to help clear the short circuit and maintain the arc.

Answer:

• 11 volts
• 24 volts
• 20 volts (Correct answer)
• 120 volts
