OVERLOAD PROTECTION

The machine is electrically protected from producing high output currents. Should the output current exceed 570A, an electronic protection circuit will reduce the current to approximately 100A. The machine will con- tinue to produce this low current until the protection cir- cuit is reset. Reset occurs when the output load is removed.

THERMAL PROTECTION

Thermostats protect the machine from excessive oper- ating temperatures. Excessive temperatures may be caused by a lack of cooling air or operating the machine beyond the duty cycle and output rating. If excessive operating temperature should occur, the thermostat will prevent output voltage or current. The meter will remain energized during this time.

Thermostats are self-resetting once the machine cools sufficiently. If the thermostat shutdown was caused by excessive output or duty cycle and the fan is operating normally, the Power Switch may be left on and the reset should occur within a 15 minute period.
