Can pulse welding be performed manually or automatically?

• A. Manually or automatically
• B. With or without filler metal
• C. Only manual
• D. Only automatic

Answer: (A)

Pulse welding is about delivering energy in short bursts rather than a constant arc, so the technique is a feature of the welding equipment and its settings, not a mode tied to a single operator type. Because the pulse control can be used with a human operator or with automated equipment, you can perform pulsed welding manually (the welder controls the pulse parameters) or automatically (a programmed or robotic system controls the pulses). The use of filler metal is a separate choice dependent on joint design, not on whether the welding is pulsed. Likewise, pulsed welding isn’t limited to one mode of operation. The key point is that pulsed current can be applied in both manual and automatic setups.
