What is arc blow?

• Rapid cooling of a hot component

• Repetitive and consistent side-to-side motion

• Localized melting of the base metal caused by the initiation of an arc

• Deflection of the arc from its intended path due to magnetic forces

• Localized melting of the base metal caused by the initiation of an arc

• Repetitive and consistent side-to-side motion

• Rapid cooling of a hot component

What is drag angle?

• A type of weld bead made by transverse oscillation of the electrode in a particular pattern
