[kill_shot]

hello all I have been looking through this site for a few months and just finaly registered.great site.
I am thinking of buying an new welder I was gonna buy a miller 251 mig but then i would also like to buy a tig in the next couple of years.I use a multimaster at work and don't mind it for mig but we don't have the tig setup for it so I havn't used it.does anyone have one of these or have any experiance with them?if so how do they work compared to a tig only unit?
thanx in advance for any help

I may be wrong, but I think the multi-process machines will only tig DC. You need AC to tig aluminum. I think it would be better to buy two separate machines.
