My big 40 is burning up my grinders. How do I check my voltage and what should it be at on high idle ? How would you adjust it down if it's to high ?

Freq is absolutely the best check for engine speed. Get yourself a meter that will measure freq and go from there. The Kill-A-Watt meter is really great and not very expensive. I have more meters, oscilloscopes, and other electronics test gear than any reasonable person needs, but I bought a Kill-A-Watt because it's just so easy to use-just plug it in and push the button for voltage or frequency. You can also use it to see how much power various things in your house are using since it also reads kilowatts. Anything up to 15 amps. Maybe Duaneb55 or Cruizer will see this, they would both know how to set the engine speed, and I think their direction will include using a freq meter.

As I read the manual..... the 55-80 is Open Circuit Voltage for welding output
NOT Amperage related to the AUX AC outlet.... that should supply 3Kw of 120VAC @ 60Hz with the machine running at welding speed..
First...measure voltage and frequency at the outlet.... that will tell us a lot about if the governor needs adjustment
see Section 2 Page # 5

BTW how does it weld...??Last edited by H80N; 07-06-2016, 05:55 PM..

I looked up some notes I kept from old post cruiser had on this. Can probably find them if search long enough. But I'll be close. Set weld rpm. With no load. Low rpm diesel i.e. 1800 area. Set to 60.5 - 61hz. <br />
Set small gassers to 62.5 hz area <br />
And I'm guessing yours, med. gas and diesel high rpm. I.e. 3600 rpm area set to 61.0 - 62hz area. <br />
Set high or weld rpm to this hz setting with no load and should be fine.
