What to do if ON / OFF Switch is ON but the A/C Indicator does not light on Thermal Dynamics 152 CUTMASTER?

If the ON/OFF switch is ON but the A/C Indicator does not light on your Thermal Dynamics Welding System, make sure that the primary power disconnect is in the ON position. Also, the primary fuses or breakers might be blown or tripped. Another reason might be the unit's internal fuse is blown. In these cases turn primary power disconnect switch to ON position, check primary fuses / breakers or replace fuse. If fuse blows again, return to authorized service center for repair or replacement. If none of these steps resolve the issue, the unit may have faulty components.
