THEORY OF OPERATION | ||
|
THERMAL PROTECTION
The Compact Wire Welders have a rated output duty cycle as defined in the Technical Specification page. If the duty cycle is exceeded, a thermal protector will shut off the output until the machine cools to a reasonable operating temperature. This is an automatic function of and does not require user intervention. The fan contin- ues to run during cooling. If the fan is not turning or the air intake louvers become obstructed, the input power must then be removed and the fan problem or air obstruction corrected.
OUTPUT OVERLOAD
The Compact Wire Welders are equipped with a circuit breaker which protects the machine from damage if maximum output is exceeded. The circuit breaker must be manually reset.
