DUTY CYCLE

The rated Duty cycle refers to the amount of welding that can be done within an amount of time. The Eastwood MP140i has a duty cycle of 30% at 90 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 90 Amps with a
30% Duty Cycle, within a 10 Minute block of time you can weld for 3 Minutes with 7 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 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.
