Duty Cycle
Duty Cycle is a common term in welding that describes how long a welding machine can safely operate within a 10-minute period before it needs to cool down. It's usually shown as a percentage - for example, a 60% duty cycle means the welder can work for 6 minutes and then needs 4 minutes to cool off. This is important because it affects how continuously a welder can work on projects. Think of it like a rest schedule for the welding machine to prevent overheating. When reading resumes or job descriptions, this term indicates that the welder understands equipment capabilities and safety procedures.

Example Interview Questions
Senior Level Questions
Q: How do you determine the appropriate duty cycle for different welding projects?
Expected Answer: A senior welder should explain how they consider factors like material thickness, project timeline, and equipment specifications to choose the right machine and manage work periods efficiently.
Q: How do you train others about duty cycle management?
Expected Answer: Should discuss their experience teaching others about equipment limitations, cooling periods, and how to plan work schedules around duty cycle requirements to maintain productivity and equipment safety.
Mid Level Questions
Q: What happens if you exceed a machine's duty cycle?
Expected Answer: Should explain the risks of overheating, potential equipment damage, and safety procedures for proper machine operation and cooling periods.
Q: How do you adjust your work schedule based on duty cycle?
Expected Answer: Should describe practical examples of planning welding tasks around equipment cooling needs while maintaining productivity.
Junior Level Questions
Q: What is a duty cycle in welding?
Expected Answer: Should be able to explain that it's the amount of time a welding machine can operate safely within a 10-minute period before needing to cool down.
Q: How do you calculate a 60% duty cycle?
Expected Answer: Should explain that with a 60% duty cycle, the machine can weld for 6 minutes out of every 10 minutes, with 4 minutes needed for cooling.
