Duty Cycles

I am looking at a new mig welder over 200amps, single phase, for home. However could some-one please explain to me about duty cycles. There are two units which I am deciding between but there is a vast difference in duty cycles . The first machine is 200amps. It's duty cycle is: 200a @ 60%, 155a @100%. The other machine is 210amps and it's duty cycle is: 210a @ 20%, 120a @ 60%, 90a @ 100%. I appreciate your help. Thanks, Rossco.

Re:duty Cycles

Hi the easy way to look at it is 10% equals 1 minute so 200 amps at 20% is at 200 amps you can use it 2 minutes out of 10 minutes at 200 amps TROY

Duty cycle

The duty cycle is the amount of time that you can actually weld with the machine at a given amount of amps. An example would be if the machine is rated at 60% duty cycle at 200 amps, then you should be able to use the machine for 6 out of ten minutes without stopping, if you have it set to run at 200 amps. On most machines the lower the amp setting, the longer you can weld without letting the machine rest. Most medium duty machines are rated at 60% duty cycle. My personal choice would be not to choose a machine that had less than a 60% duty cycle at close to the max amps.
