3-4. Duty Cycle And Overheating For Non-CE Model

For Units Connected to a 20 Ampere, 115 Volt Circuit or a 10 Ampere, 230 Volt Circuit:

35% Duty Cycle At 21 Amperes, 88 volts dc

For Units Connected to a 30 Ampere, 115 Volt Circuit or a 15 Ampere, 230 Volt Circuit:

35% Duty Cycle At 27 Amperes, 91 volts dc

60% Duty Cycle At 21 Amperes, 88 volts dc

100% Duty Cycle At 17 Amperes, 87 volts dc

35% duty cycle

Duty Cycle is percentage of 10 min- utes that unit can cut at rated load without overheating.

If unit overheats, thermostat(s) opens, output stops, Temperature trouble light goes On, and cooling fan runs. Wait fifteen minutes for unit to cool or temperature light to go off. Reduce amperage or duty cycle before cutting or gouging.

YExceeding duty cycle can damage unit and void warranty.
