Far as I'm concerned today, the only junk HF stuff is the 'Warrior' line. The rest is pretty good. Even the Pittsburg stuff is acceptable but the Chief and Icon and the tool cabs are all excellent as are the Vulcan and Titanium welders and plasma cutters.
I have a Vulcan Pro-Tig 205 and it is much better and tons cheaper than my Lincoln Square Wave TIG which I've sold and I bought 2 Titanium plasma cutters a 65 amp for use on my CNC plasma table and a 45 amp for general hand use. and both were less than the Hyper-Therm I had that I sold as well. All the Vulcan and Titanium welder come with a one year guarantee which I extended to 3 years.
The Pro-Tig is especially user friendly with it's built in presets and full digital control. I did upgrade the standard TIG torch to a CK 250 amp water cooled unit and a water cooler however. The gas cooled torch isn't good for aluminum welding at maximum amperage. It's only a 150 amp torch.
When I purchased the Pro-Tig and the Vulcans I also purchased the Large Vulcan roll around welder cart. It's also a high quality piece. Ball bearing soft lock drawers, room for 2 full size bottles (I run 120's) on everything that requires gas shielding except my OA torches. They get a 180 OX bottle and a A sized acetylene bottle, or maybe it's not an A, it's a big one too... I keep my Hobart 210's separate carts.
