Under normal working conditions the overheating indicator is not visible. However, should
the machine exceed its working duty cycle, welding will cease and the thermometer symbol
will illuminate indicating that the machine has overheated. The cooling fans of the machine
will continue to operate. When normal operating temperature is regained, the machine will
reset and welding can continue. The overheating indicator will no longer be visible.
