I ran across a used Econotig, complete with air cooled torch, very low hours, no bottle at well less than half of retail sticker. This would be for my home shop. I occasionally use an Lincoln Synchrowave 180 SD at the prototype shop, don't really get into the exotic welding. Main use would be thin steel tube (.032" to .120 wall), .062" to .120" 6061 aluminum, and a bit of stainless.
I know the Econotig is really plain jane but the price is very attactive. Are there any "must have" features that make it worth going to a more full featured machine?
