Analyze the image

The image shows a welder holding a welding torch directly by hand to perform the weld.

Identify the welding method

In manual welding, the welder controls both the torch movement and the filler metal feed by hand.

Evaluate the options

• Automatic: The machine performs the entire operation without manual intervention.
• Manual: The operator manually controls the entire process. This matches the image.
• Semiautomatic: The machine feeds the wire, but the operator guides the gun.
