I have always wondered why they keep the ARC capability on those welders... I guess everyone needs pipe fences but I would think that MIG would be so much more efficient at this point.
One interesting thing I learned up at Mark Gerish's Metal Shaping Academy is that many old school panel beaters prefer gas when they have to weld on aluminum panels they are fabricating because TIG keeps the heat so close to the weld that the metal becomes brittle relative to the rest of the metal and is more prone to cracking when working the panel. Gas welding apparently distributes the heat more evenly and this isn't an issue.
