Miller Millermatic 212
A gas metal arc welder where the weld is produced by heating continuous filler metal. Capable of welding all types of commercially available metals and alloys.
Any welder worth their salt has probably used a miller, and probably used a Millermatic 2012. This machine is completely capable of welding up industrial joints or that fine sheet metal you’ve been looking at for your cafe racer.
Plus, it being a MIG welder, your crappy welds can easily be hidden under a layer of weld, then ground away.
