Why is the power LED off and the fan not working on my Jasic Welding System?

If the power LED is OFF and the fan is not functioning on your Jasic Welding System, it could be due to several reasons. First, check if the primary supply voltage has been switched ON or if the input fuse has blown; replace the fuse if necessary. Second, ensure the welding power source input switch is switched ON. Finally, check for and secure any loose internal connections.
