In SMAW welding, what does 'Hot Start' do?

• A. Provides an additional boost of current when striking the arc.
• B. Increases travel speed
• C. Increases penetration
• D. Decreases slag

Answer: (A)

Hot Start is a feature that temporarily increases the welding current right after you strike the arc. That brief boost helps ignite the arc more reliably and reduces the chance of the electrode sticking to the workpiece, giving you a stable arc quickly. Once the arc is established, the current returns to the normal welding setting. This makes it especially helpful for starting welds with coated electrodes, but it doesn’t by itself change travel speed, long-term penetration, or slag behavior.
