Match the following options with their correct descriptions.

• The arc emits light without conducting electricity.

• The arc emits light but does not conduct electricity.

• Current flows through the air due to the formation of an electric arc.

• An electric arc is formed, allowing current to flow through the air.

• Current flow is prevented by the creation of a vacuum.

• The arc generates heat, causing the air to solidify.

• The air solidifies due to heat generated by the arc.

• The arc creates a vacuum, preventing current flow.

How does the welder manipulate the molten metal?

• The welder pours the molten metal into molds without tools.

• The welder lets the metal cool naturally without manipulation.

• The welder manipulates the molten metal using tools and techniques to control its flow and shape.

• The welder uses a hammer to shape the metal.

Match the following sounds with their descriptions during the welding process.

• Sound of gas escaping

• Buzzing sound

• Sound of electrical arc

• Hissing or sizzling sound

• Sound of molten metal cooling

• Thumping sound

• Sound of metal being struck

• Whistling sound

Why does the welder wear a protective mask?

• To enhance visibility while welding.

• To improve the quality of the welds.

• To protect against harmful radiation, sparks, and heat.

• To keep the welder warm in cold conditions.
