I have to say, EW has some pretty cool accessories for their welders. The have a pair of vise grips that you can make perfect spot welds, an attachment that welds on the pins that you use a puller to pull out dents. I have their 175 MIG and their Plasma cutter, the 175 welder comes with a spool gun just for Aluminum welding wire (other companies sell independently for $300 to $600.) Sometime coming I will get one of their TIG welders.
