Thermal arc and Parweld share some products afaik, their small tig's are identical apart from the colour and decals. Be aware that most of the smaller machines are now made in china, nothing wrong with that if you get a good warranty period. This side of the Atlantic a lot are buying a brand called r-tech, which are chinese made but have a great no-quibble warranty, if it goes wrong they will replace the unit no problem. I think this brand is everlast in the USA.
Of course if you want the best then miller and lincoln, with fronius and the french made gys are probably the way to go.
