The rated Duty Cycle refers to the amount of welding that can be done within an amount of time. The Eastwood MP250i has a Duty Cycle of 60% at 250 Amps. It is easiest to look at your welding time in blocks of 10 Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 250 Amps with a 60% Duty Cycle, within a 10 Minute block of time you can weld for 6 Minutes with 4 Minutes of cooling for the Welder. If the Duty Cycle is exceeded, the Welder will automatically shut off, however the fan will continue running to cool the internal components. When a safe temperature has been reached, the Welder will automatically switch the Welder output back on. To increase the Duty Cycle you can turn down the Voltage Output control.
