To TIG aluminum you need an DC machine, ideally with a wave or pulse arc. That's where Lincoln's Square Wave gets it's name, or my HuGong Wave 200. The quality welders will weld beer cans, but those electronics are very expensive. The $800 I paid was what KMS had likely paid, as they needed an influx of quick cash to pay for them. I had been dealing with KMS since their beginning, so I knew how they operated. The manager was moaning when I bought it. That was with an .85 dollar. Look what at ESAB wants for their 186i, same basic machine, just a much better manual. So if you are paying less than $1000, what kind of junk are you getting ?
