Can it be used with a generator?

We do not recommend using it with a generator. The voltage of the generator is unstable, and the machine will repeat the voltage conversion to reduce the life of the capacitor. If it must be used with a generator, the voltage must be stable, and the output power must be more than 7KW.

If you have tried all the above, it still can't be solved. If you can, please try to open the cover to adjust the distance of the discharge nozzle.

1. Disconnect the power
2. Open the cover
3. Find the location of the discharge nozzle
4. Adjust the distance between the two small iron pieces a little bit wider
   PS: Please refer to the below picture for the discharge nozzle.

Since there will be residual electricity inside the cover, Please wear insulating gloves or other insulating tools to avoid direct contact with internal circuit boards or parts.
