That should get a 'conversation'

started!
Actually I have the 120V/90amp HF mig and I've done a few decent repair projects with it. After a little experience I'm convinced this model is what they use in China to cobble together all the sloppy-welded bookshelves etc for Walmart and Target. It is sufficient for this kind of work but only within a limited range of projects. It seemed to have a very narrow range between insufficient penetration and burn-through. Aside from the limitation of low power, its AC arc and flux-only operation will always spatter more than a DC shielded-gas welder.
Then more recently I bought a used 120V Century 135 mig welder, and use it with flux wire. It adjusts through a broader range than the HF welder did, and the DC spatters less. I like it a lot better than the HF welder. It feels like I can tune it in better to match what I need, a lot better than the HF's hi/lo heat adjustment that never matched the project.
I'm still curious how the Clarke/Forney 110v welder compares to this Century.
