Which term describes cutting with a torch that is moved by a machine but adjusted by the operator?

• A. Manual torch cutting
• B. Automatic cutting
• C. Semiautomatic cutting
• D. Plasma cutting

Answer: (C)

Semiautomatic cutting describes a setup where the torch’s path is moved by a machine, guiding it along a programmed route, while the operator still makes adjustments to cutting conditions during the run (such as speed, torch height, and feed rate). This combination—machine-controlled motion with the operator controlling the cutting parameters—fits the scenario best. It’s different from manual cutting, where the operator moves the torch entirely by hand, and from automatic cutting, where the machine handles both movement and all settings with little real-time intervention. Plasma cutting is a process type and can be done in different modes, but the described situation specifically matches semiautomatic cutting.
