This is probably going to stay on my wish list for a good long time, but
I've been lusting after TIG welding capabilities for a while now.

Nearly all the projects that I have in mind at the momet involve
welding .03" to .06" aluminum sheet to itself and to 1/8" or 3/16"
bosses, so it looks like this thing is heavy-duty enough.

So, is it a good buy?

No it's not a good buy. Nothing Eastwood offers is a good buy.

Be sure to check the minimum current of any TIG welder you buy. The original Miller Econotig had a minimum current of something like 30 amps. So it would not adjust down to a low enough heat to weld .03 aluminum.

And of course remember that you will need a cylinder of argon , flow regulator, and 220 volt power outlet.

Have you ever tried TIG welding thin aluminum with a high-end machine,
at night school for instance?

It isn't as easy as mild steel or stainless. I stopped trying to learn
when I retired and no longer wanted it on my resume.

No. I've been thinking of taking a welding class at the local Community

I can certainly believe that it's more difficult -- I know I could do
this job in a heartbeat with steel, with my gas torch. I've been tempted
to get some aluminum rod and gas welding flux and giving it a whirl, but
I have a sense that it'll take as long or longer to learn as doing it
with TIG, and that the result would never be as good.

I have an Everlast 250EX , much cheaper than that Lincoln or a Miller ... I
can light an arc on the bottom of a pop or beer can and run a bead , but
welding 2 of them together is still beyond my skill level . IIRC mine will
light up as low as 5 amps . It has all the same features as the Big Names ,
and would be a good starting point - if Tim had about double the budget .

Looking at the specs for the AHP , it shows the minimum current as 10 amps. The rule of thumb is one amp per .001 inch of thickness. But I think that is where you set the max current. And then you use the foot pedal to get the current right. So when welding say .063 aluminum you would set the amps to about 90 amps ( 50 % more for aluminum ) , but when you are welding you may only be using 45 amps. And as you approach the end of the material , you would feather off to maybe 20 amps. So the AHP ought to be okay for 1/16 aluminum. But on .030 aluminum , you might want to feather down to ten amps. And that is as low as you can go. Anyway I would want to try the AHP on .030 aluminum before buying the machine.

If you keep looking on Ebay and Craigslist, you may find a older Tig welder for about 3 or 4 hundred. The disadvantage is they are heavy and need more power than an inverter TIG.

I have a Lincoln SquareWave TIG 300. Truly an awesome machine, even though
pretty primitive by today's inverter welder technology. I've never tried to
do anything quite so thin, but my machine has a VERY smooth, soft start. It
is so smooth, you can't be exactly sure when the transition from HF to AC
TIG happens! The machine clicks when the preflow timer ends, but the main
welding current takes about a second extra to develop. Once you pour on the
current, the hum of the AC arc makes it clear welding current is flowing.

I know you can set the current down below 5 A, I've done it while watching
the meters. Of course, you can't watch the meters and actually weld
anything, or at least I can't.

I have done some aluminum extrusions and also copper, which might actually
be harder to control the heat than aluminum. You've got the whole piece
within a few degrees of completely melting all the time.

The old Lincoln Idealarc 250 and 300, would on low range..start at "3"
amps. When in bad shape..they would start at 5-8 amps

My Squarewave 300 will start at 3-4 amps on low, and with process
controls on...I can get pulsed (selectable) 3 amp ac/dc. Welding beer
cans is easy. It will also go up to 425 amps..but to get over
250ish..it needs a 100 amp breaker...

That machine..is one of the FINEST welders ever made. Primitive or
not...it will do just about any damned thing you can want of it. Heavy
as hell...and draws a fair amount of power..but its better than a
Syncrowave 300 and as good as my welder.

And in that video, he really seems to like the AHP more. I plan on buying one of those very soon (hopefully before the end of this year). for an extra $50, I think you get a lot more. AND, you can buy it from Amazon, which gives you another layer of protection.

Looking at the specs for the AHP , it shows the minimum current as 10 amps. The rule of thumb is one amp per .001 inch of thickness. But I think that is where you set the max current. And then you use the foot pedal to get the current right. So when welding say .063 aluminum you would set the amps to about 90 amps ( 50 % more for aluminum ) , but when you are welding you may only be using 45 amps. And as you approach the end of the material , you would feather off to maybe 20 amps. So the AHP ought to be okay for 1/16 aluminum. But on .030 aluminum , you might want to feather down to ten amps. And that is as low as you can go. Anyway I would want to try the AHP on .030 aluminum before buying the machine.

If you keep looking on Ebay and Craigslist, you may find a older Tig welder for about 3 or 4 hundred. The disadvantage is they are heavy and need more power than an inverter TIG.

I would love a $7/800 welder. Less than a penny sounds great, as long as
the thing works.

My suspicion is that for what I want, a new el-cheapo welder will be
better than a nice older machine -- I suspect that if I were doing normal
stuff in a normal shop (i.e., not really thin stuff) that I'd feel
differently.

Yes, Ernie Leimkuehler said the same thing, which is why I snagged it when

I was looking and drooling awhile back too. I really liked the looks of
the Thermal Arc 186 AC/DC:

I figured around $2000 to be safe, get it ready to go with argon, some
consumables and such...

Sure are a bunch of almost affordable choices nowadays ;-)

I also offered up the URL of the best Craigslist search engine Ive
ever found. The list of machines I posted was done in less than 5
minutes. It also showed that cheap machines are hard to find, even on
Craigslist. There was (1) (old) $500 Miller on Ebay..but it will
need the torch, cooler, pedal etc etc...bringing the price up
considerably.

If the suitcase welders are what he can afford/need, Id suggest he
find one with the best reviews and buy it.

However..I would...would further suggest he do a Craigslist search
engine search in his area for a few weeks and see what turns up. And
do NOT be afraid to call the seller and haggle, particularly for
machines that have been up for 6 or more days. As the economy slows
down yet again....Im seeing more "hobby stuff" appearing on Craigslist
and very reasonable prices.

Set a deadline of say..1 month..and hit the ads regularly and
hard...if you dont fine a lincoln or miller at his price range..then
jump on one of the Chicom Inverter suitcase machines. By all
reports..they are decent enough for the price. Just remember...if
they break..there is ZERO repair sources for them ,generally that dont
involve big shipping costs both ways.

There are epoxies that claim 500 F. That seem cheaper than a

Ernie is the man as far as welding goes. He reads SJEW , but it might take a while to get an answer. You might consider getting a small DC Tig welder. They are pretty cheap especially if it is used. Here is some info an welding aluminum using DC tig.

Ernie for tig welding all the steels I do I use DC (EN), My welder also has the option for DC (EP), Can I use this for tig welding? If so what materials or use for?
Thanks

Answer
DC Electrode Positive will work for aluminum and Magnesium.
AC works better, but DCEP does work.
The problem with DCEP is that the majority of the heat is coming back at the tungsten, so the tungsten gets very hot.
This limits the capacity of DCEP as to thickness of aluminum.
The simple rule is the tungsten has to be at least as thick as the aluminum.

Even if you have AC on your TIG you can use DCEP to ball the tungsten before welding with AC.
You will get a better ball.

Those are for gasoline or diesel four-strokes, and you're mostly quoting
temperatures that would melt an aluminum muffler off of the engine -- and
in model airplane service, if a muffler isn't aluminum, there's a good
chance that it's carbon fiber.
