PROCESS LIMITATIONS

The ASPECT 375 is not recommended for pipe thawing or for arc
™
gouging.
EQUIPMENT LIMITATIONS
The ASPECT 375 is protected from overloading beyond the rated
™
duty cycle and outputs of the machine. The duty cycle is based
upon a 10 minute time period; a 30% duty cycle refers to 3
minutes of welding and 7 minutes of idling. If the duty cycle is
significantly exceeded, the thermostatic protection will shut off
the output until the machine cools to a normal operating
temperature.
