In welding terminology, what does "duty cycle" refer to?

• A. The ratio of welding time to idle time
• B. The number of welds performed
• C. The temperature of the welding arc
• D. The amount of filler material used

Answer: (A)

"Duty cycle" refers to the ratio of welding time to idle time, typically expressed as a percentage. It indicates how long a welding machine can operate at a specific output before it needs to cool down. For instance, a machine with a 60% duty cycle can operate for 6 minutes out of every 10 minutes at a specified output, while the remaining 4 minutes allows the machine to cool down. This measurement is vital for ensuring that the equipment does not overheat and can function reliably over extended use. Understanding the duty cycle helps welders manage their workload effectively and avoid damage to welding machines, thus maintaining efficiency and safety on the job site.
