Well, not sure if I am 100% there yet, but I've been looking at TIG's lately. I've done a bunch of welding including TIG in the past, but never had my own machine. For a while I was working as an industrial maintenance tech. and that particular position involved a lot of SS TIG welding... so I've done a lot, but with that said I'm still not an expert.
I am looking for something with AC/DC, enough power to weld aluminum, though I don't expect to be welding heads or anything that large. Think plenums, brackets, SS exhaust, charge cooler pipes, etc. I already have a lincoln MIG, so that side of things is covered.
Price range is up to about $2500 or so. I've got 3 options in front of me:
1) Used Lincoln PT185 - $2100 compete with torch, pedal, kart, etc.
2) New Miller Diversion 165 - $1825 after taxes
3) Used Miller synchrowave 180SD - $2000 with accessories
I'm leaning towards option 1. I think the millers are in general slightly better machines, but I like the added features of the PT185. I know that none of these machines are super heavy duty production machines, but they are for personal/hobby use with a few side jobs as well.
Comments from those with any of the above machines, or the experienced welders are greatly appreciated.
