My magnetron is used in the industry, my dedicated power to start less than 2 minutes to stop,
3 power matching problem If you choose the magnetron power is lower than the lamp, the same point is not lit or strobe
4 waveguide shade design problem if you have mature technology this can be discharged
2 power supply general power supply has a self-protection function is not the same as the heat can not work
This reason is much better, next to the investigation
1 heat problem magnetron with or without cooling fan, generally if there is no cooling or cooling broken, then the magnetron will work for 2 minutes to burn, you measure the same as the filament is passed. Burn is a magnet cracking
