I recently brought this welder over to a friends because he was dubious it was as good as I was describing it. We took a 50' extension cord out to the steel scrap pile, took out some smaller 7018 rods and started welding at 90A. After burning through several rods, and successfully joining several pieces of totally unprepared scrap we tried some tig brazing and it worked great too.My friend went inside and ordered a unit for himself.I used to recommend gas tanks when people asked me what to get for a first welding setup but now I recommend this unit.It welds automotive sheet metal beautifully with almost no clean up. If you spend even a little time prepping your welds this can give you great results. It comes with a 1/6 tungsten holder and tungsten which is good for sheet metal, but if you need to weld anything thicker, you will need to get a (quite inexpensive) set of larger collets and cups. The consumables for this unit are readily available and inexpensive.Of course this machine does not perform miracles, but if you can weld or are willing to learn this machine will hold up it's part.The machine is DC so it will not weld aluminum and it has HF starting so no scratching necessary.
