Summary: | Systems, methods, and apparatus to control weld current in a preheating system are disclosed. An example preheating power supply includes power conversion circuitry configured to output welding-type power via a first output power connector and a second output power connector, and a bypass path prevention circuit configured to prevent less than a threshold voltage applied to the first output power connector and the second output power connector from a different power supply from causing current to flow between the first output power connector and the second output power connector. |
