Summary: | A method and apparatus for providing welding-type power supply includes a power circuit and a controller. The power circuit receives input power and provides welding type power and auxiliary power. It is controlled on a control input. The power circuit also includes an auxiliary power transformer. A temperature responsive component is mounted in the auxiliary power transformer and provides a temperature signal indicative of the temperature in the auxiliary power transformer. The controller controls a cooling fan for the aux power transformer and/or turns off the aux power output in response to the sensed temperature. |
