This welder/generator does not produce clean power like an inverter style generator. In most cases, your RV A/C unit does not require a low total harmonic distortion generator.

Will this welder produce clean electricity to run my RV's Air Conditioner or do I need an inverter style generator?
I understand there's plenty of watts and I have no intention of running a TV or Computer with this Welder but I'd like to run a simple AC Unit and maybe even a microwave..

It should work fine. "Dirty" power can effect certain electronics but simple electrical devices should be OK. If the microwave is basic I would expect it to be fine but a microwave with all of the electronic bells and whistles may have issues.
