Abstract
A welding-type system with a programmed controller and alert devices for alerting a user as to the impending thermal shutdown of the welding-type system.
Claims19
A welding-type system, comprising:
- a device susceptible to an excessive temperature condition;
- a temperature measuring circuit with a sensor to measure a temperature of the device and generate an instant temperature value;
- storage in which is stored a predetermined shutdown temperature value and (a) a lower, predetermined pre-shutdown temperature value, or (b) a predetermined temperature offset value;
- a device controller coupled to receive the instant temperature value from the temperature measuring circuit, the control circuit programmed to compare the instant temperature value with (a) the predetermined pre-shutdown temperature value or (b) the predetermined shutdown temperature value less the predetermined temperature offset value and generate an alert signal depending on a result of the comparison;
- and
- an impending shutdown alert controller coupled to the control circuit.
A welding-type system comprising:
- an instant temperature determination unit;
- a data processor in communication with the instant temperature determination unit;
- memory in communication with the data processor and storing a thermal shutdown temperature value and an impending thermal shutdown temperature value or a temperature offset value;
- and
- an impending shutdown alert signal generator in communication with the data processor, wherein,
- the data processor is programmed to cause the impending shut down alert signal generator to generate an impending shutdown alert signal when an instant temperature determined by the instant temperature determination unit at least is greater than an impending thermal shutdown temperature.
A welding-type system comprising a controller board including a processor programed to monitor for an over temperature condition of an apparatus, to invoke a thermal shut down routine when the over temperature condition occurs, place the system in an error state, and maintain the system in the error state until the over temperature condition is cleared.
