What does the term "duty cycle" mean? Duty cycle is a welding equipment specification which defines the number of minutes, within a 10 minute period, during which a given welder can safely produce a particular welding current.. For example, a 150 amp. welder with a 30% duty cycle must be "rested" for at least 7 minutes after 3 minutes of continuous welding.

The Miller is also a transformer-based machine, whereas the Longevity is an inverter-based welder. The Millermatic's duty cycle is 60% at 200 amps and 40% at 250 amps, so they're pretty close as ...

The only problem with calculating a duty cycle over a different period, especially a longer one is it is no longer accurate. For instance, if duty cylce is calculated over an hour, the 50% @ 200 amps would mean that a welder could put out 200 amps for 30 minutes straight.

Duty Cycle is how long you should run your welder before it’ll shutdown. Duty cycle is given in a percentage out of 10 minutes. For instance, the Millermatic 212 at 160 amps (at 24.5 VDC) has a 60% Duty Cycle. This means it can weld continuously for 6 minutes straight before it has to reset itself.

This should be a sticky. Most welders are sold with a 20% or 40% duty cycle rating. But what if you want to know the duty cycle at other amperages? The owner manual doesn't tell me that at all. Nor does it tell me how to figure it out. So here you go guys. An equation to post on your shop wall. You may never use it or may use it just once.

A low duty cycle can often cause a purchaser to buy a welder with a much higher amperage rating. For example, a prospective buyer who wishes to get a welder with a 60% duty rating at 160 amps may have to purchase a 250 amp welder with a duty rating of 30% at full power in order to achieve the required duty cycle of 60% at 160 amps. Duty Cycle ...

What Is Welder Duty Cycle and Why Should You Care? Kevin takes a break from working on his latest sculpture to compare the duty cycles of three different welders and explain what duty cycle is and why it's important. The first machine is the Longevity ProMTS 200, which has three welding functions in one machine: MIG, TIG and stick (or arc).

en.wikipedia.org/wiki/Duty_cycle

A duty cycle or power cycle is the fraction of one period in which a signal or system is active. Duty cycle is commonly expressed as a percentage or a ratio. A period is the time it takes for a signal to complete an on-and-off cycle. As a formula, a duty cycle (%) may be expressed as: = × %
