OVERLOAD PROTECTION
The machine is electrically protected from producing
high output currents. Should the output current exceed
430A, 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.
