| It takes a little more detail than what you provided to accurately size a generator.
Is the 180 amp welder a wire welder...if so, a 180 amp Miller will consume about 5 kw at rated output. A stick unit would be much more.
More importantly, What size motor on the air compressor and and what voltage. Motor loads are the most difficult for a generator to start. Locked rotor kw rating (which is the starting load) could be as much as 3 to 4 times more. A good example would be a 5 ton a/c unit would typically draw 5 kw running yet starting kw load would be 15 kw.
Provide that information an size can be derived.
