@Nicad and
@bfeng,
I have only used TIG on steel. I had a few requirements. I want a tig because it is ve try quiet and doesn’t throw sparks. Sparks burn my epoxy floor. I also really like the bead that TIG lays. They aren’t great for body work because they are slow and require footwork. So my requirement was a thumb control. This cheap TIG only has an on/off without flow. I spent another $150 on a nice flow meter. Fortunately the gauge of my material will be constant and a fixed thumb control should be adequate. I also wanted high frequency so I didn’t have to scratch start. I do plan to weld aluminum in the future so I wanted an AC/DC tig. Otherwise I would have purchased the Harbor Freight Vulcan 165 two years ago.
My mig is a terrible flux core that I totally abuse. The tig came with an extra tank so I’ll likely pickup a low-end blue or red mig. I’m honestly pretty sloppy with Mig, even with a good machine. I have a lot of time on my POS buzz box but you will never get great welds from a cheap 110v flux core.
This HF TIG is on sale for $899 through June (coupon online). I personally think it is the best Tig money can buy. HF completely ripped off Miller with the Tig 200. They took it down for a year, made some Chinese interpretations of the patent, and released the 205. In reality we should all be buying American welders right now but I don’t have $2,500+ to spend.
Amazing deals on this Protig 205 Industrial Tig Welder at Harbor Freight. Quality tools & low prices.

I picked up this mine for $450 with two tanks, thumb control, and some consumables. I figured even if the welder craps out I’ll have a head start on the collateral bits.
