Hi,

I've got a mig welder set up primarily for steel (w CO2/Argon tank),
but I've wanted a Tig welder for sometime. Ideally this Tig welder
could handle up to 1/4 aluminum plate, although less could be okay.
Any recommendations? Duty cycle does not need to be high(just a home
shop), but needs to run on 220v single phase power.

Thanks
Chris

Can't tell you which machine is best, but be aware that 1/4" AL will take
some serious electric circuit. I ran 50 amp 220 to mine and this is not
large enough. I'll be moving my Lincoln stick/TIG machine to a 100 amp
circuit.

Thanks, I was afraid of that. I have a 50 amp service as well.

To weld 1/4" aluminum with TIG requires at least a 250 amp machine, but
300 is more like it.
A Miller Syncrowave 250 maxes out at 310 amps, and I can tell you from
experience on mine that it will do 1/4" aluminum, but it does need a 80
amp circuit of 220 volt single phase to do that.

If you went to an inverter, like a Miller Dynasty 300DX then you could
run it from a 50 amp circuit, but the machine would cost you around
$4500.

It would be much simpler to run a spoolgun off of your MIG and simply
wire feed your aluminum.

I have had their model 10250 version for 6 years and love it a lot.

If you don't mind busting yer ass (pre-heating, tig'ing on bricks, tig both
sides, etc), a Miller Econotig can eke out 1/4", but you really have to bust
yer ass.
Fillets would be out of the question!
Does stick AC/DC, tig. Not true high freq, but a decent facsimile.
Groans on 3/16, OK on 1/8.
Overall nice machine. $1300 ten years ago. 50 A OK.

Oh, you're sunk! I have a Lincoln Square Wave TIG 300, and it
can just barely weld 1/4 Al, acording to the manual - I've never
tried anything that big (yet). You will probably need Helium
gas to get higher heat, too. And, a 70 A minimum feed for just
the welder, and 90-100 preferable.
