Several posters have inquired about HF's Titanium series, in particular the 110 volt 125 Flux.
Only recently has HF started offering pro-quality anything. If these posters are asking about HF gear, then they aren't willing to pay the price for pro gear like 5050 does. They are defining themselves as a typical HF customer, a DIY type or other class of amateur, likely hobbyist, in most cases a beginner who doesn't know what he needs.
Everlast is in the pro category, at some multiple more expensive than what HF is known for. (Just recently HF has moved up to offering welders competitive in specs to the traditional vendors. Suspicions remain whether these units will have the manufacturer support long-term that the traditionals do).
Yep. You and I seem to do 90% of the replies when someone wanders in there.

I still feel an obligation to check in there occasionally because I was the one who told M about WeldingWeb going dark, with potentially a lot of orphan posters out there who might migrate to a new site if he established one.
But then months later WW got sold and came back online. The folks who need to talk about their pro shops and their pro gear resumed posting to one another over there.
