Why is my Pro Spot SP-5 DP machine powered ON, but not working?

Your Pro Spot Welding System might not be working due to several reasons: * The thermic protection might have been triggered because of overload or exceeding the duty cycle. Respect the duty cycle of the machine. * The thermic protection might have been triggered because of overtemperature. Allow the welder to cool. Wait until the pilot lamp on the wire feeder front panel is off, indicating the thermostat has closed. * The fan may be obstructed. Free the fan from possible obstructions or replace it.
