In a portable generator.

Does one type of load vs the other make it more difficult for a typical
portable generator to maintain constant voltage?
Esp at a current approaching the continuous current limit of the generator.

I ask bec the mfr claims 1-2% regulation. A small miller welder is causing
12%+ variation, within the current limitations, with the voltage variation
being fairly proportional to load. I'm assuming a transformer load is
substantially inductive?

I haven't yet tested it with purely resistive loads, cuz, well, this would
require a lot of heaters, a pita to wire up.

Hi,
In real world situation you will have hard time finding purely resistive
load. Most loads are inductive affecting power factor. IMO, your
generator maybe border line under powered for the welder.
