GMAW may be used in the semi-automatic or automatic operation modes.

• A. True
• B. False
• C. Only semi-automatic
• D. Only automatic

Answer: (A)

Gas Metal Arc Welding is designed to be controlled by either the operator or by automation. In semi-automatic mode, the welder guides the torch and controls travel speed, while the wire feed and shielding gas are handled by the equipment, giving reliable control with manual movement. In automatic mode, a machine or robot takes over the torch travel and wire feeding, enabling consistent, high-volume welds with little or no manual torch manipulation. Because the process supports both levels of control, it can be used in either semi-automatic or automatic operation modes.
