Which term below tells the welder how long the welding machine can be used during each ten-minute period?

The term that describes how long a welding machine can be utilized during each ten-minute period is known as the duty cycle. The duty cycle is a critical specification that indicates the maximum amount of time a welder can operate without overheating and the time it needs to cool down. For example, a duty cycle of 60% means that the welder can be used for six minutes continuously out of every ten-minute period, followed by a four-minute cooling period.

Understanding duty cycle is essential for welders to ensure they are operating within the machine's limits to avoid damage and maintain performance. It helps welders plan their work efficiently, especially during extended projects that require sustained operations. Other terms like open circuit voltage, rated output current rating, and input power requirements are also important in the welding process but do not directly relate to the duration of safe operation within a ten-minute timeframe.
