... There are 3 reviews on HF website but they are all from the same location.
All, within commute distance of HF's main office. Maybe they gave them to employees to try out.
Actually over on Welding Web the HF forum there has reviews of the new Vulcan welders by someone who was given prototypes to run in a production environment, and a couple of first-impression reviews by people who bought them as soon as they came out. There's a lively discussion going on there but it's still mostly speculation and discussion of marketing strategy. Its just too soon at present.

Harbor Freight
One thing I learned reading there is HF's warranty on these is 'return it for any reason, or no reason at all' for a full refund, for a year. How's that for a marketing strategy to move product! Buying a warranty covering the second and third year isn't too costly, it's probably a good idea with no service available for these.
My impression is HF is trying to take over the role Craftsman abandoned and the Vulcan welders are fully competitive with the box-store welders that weekend hobbyists buy.
For daily professional use? Its too soon to determine. That one prototype tester liked some models, said he quit using another model the same day it arrived, but the production units he finally received resolved all the critiques he had made while he used them in a production shop.
I'm impressed with the simple and obvious setup they have. Knobs or a video screen with menus, just set material type, thickness, rod or mig diameter and type, and the machine is all set without having to experiment. Of course you can adjust up/down from what it chooses for you. They even include a material thickness gauge. For the weekender these features cut through the mysteries of proper setup, just dial in your parameters and get to work welding. I could use that but I'm cheap. What I already have (at far less cost) has proven sufficient for my farm repairs:
