Since I sent that last message, Todd pointed out another TIG option- the inverter type machines.  He mentioned the Lincoln Invertec V205-T, and I also noticed a Miller Dynasty 200DX.  Both of these can do anything I could ever need, and will work on 110 or 220 single phase.  The biggest problem I had with the transformer type machines was the input power requirement.  I would have had to install a 50-60 amp 220 service at home, and 220 isn’t available at all at the hanger.  The inverter options are much more appealing, though about $1000 more expensive.  Oh well, it will give me that much more incentive to learn how to use it. 

 

Has anyone ever tried one of these inverter type machines?  Any preference between the Lincoln and Miller?  Here’s the Miller comparison page.
