What is the percentage of time a welding machine can be used continuously?

The percentage of time a welding machine can be used continuously is typically referred to as its duty cycle, which is often expressed as a percentage over a 10-minute period. For example, a machine with a 60% duty cycle can be used for 6 minutes of welding followed by 4 minutes of cooling. Duty cycles vary based on the type of welding machine and its specifications, with common values ranging from 20% to 100%. Always refer to the manufacturer's guidelines for the specific duty cycle of a given machine.
