My AVR has two adjustment screws, can anyone tell me why two? Is there one for each 110v winding?

What's the correct procedure for adjusting the AVR and is 220 v the correct voltage or can i go to 240 v which some of my power tools state is their input.

I just replaced the AVR and im getting 100 v from each winding.

What is your model?

The AVR model is KI-DAVR-50S and it's for a Kipor genset.

The pot nearest the edge adjusts the output voltage. This is self-exaplanatory.

The other pot (near the capacitor) adjusts the "overload" status condition, which is indicated by the LED. The way I understood it is that you fully-load the generator to capacity then adjust the pot to the left (CCW) until just before the LED lights up. So if the load goes above 100% (or whatever you set), I imagine that the AVR goes into overload and cuts power to the exciter and consequently, cuts power to the output. This is just an educated guess.

Can a welding transformer be used as a 5 kw load bank to set the overload protection ?

Welding is not my field of expertise. For as long as you can present a steady and known-quantity load to the generator, you should be able to dial in the overload setting. Popular choice is to use several space heaters as a load bank. They have a power factor of 1 (resistive) so you know that the kVA and kW are the same.

^ I would second that. The power factor can throw you for a loop and you won't really know where the gen overload is set.

resistance load bank is the best way.
