OPERATION

OVERLOAD PROTECTION

THERMAL PROTECTION

The Power Wave has thermostatic protection from excessive duty cycles, overloads, loss of cooling, and high ambient temperatures. When the power source is subjected to any of these conditions or any of the con- ditions mentioned above, a thermostat will open. The yellow high temperature light on the case front comes on. See Figure B.1 for location. Machine output is disabled, and welding is not possible until the machine is allowed to cool and the High Temperature Light goes out.

OVER CURRENT PROTECTION

The Power Wave 450 is limited to producing 750 amps peak currrent. If the average current exceeds 540 amps, then the peak current will be limited to 100 amps until the average current decreases to under 50 amps.
