Ive got the opportunity to pick up for nearly nothing or trade..a box
which I believe is a micro-tig unit. The owner called me and asked me
if I wanted it and gave me the info on the front panel

Union Carbide Linde Plasma Needle Arc Welder

I saw the unit a couple weeks ago for a few seconds, and it indeed
does have a tig torch tip with tungstun needle and coolant lines and
all that stuff. Its about the size of a bread box or a large old
style Kenwood stereo, typical Linde yellow face, lots of dials and
knobs and whatnot. I believe its 110v. There is an multipin jack for a
"remote" but there is no peddle.

I was a bit put off because there are two gas input lines in the back.
One for argon, and one in and out for a gas I dont remember..CO2?
Must be the coolant line that goes out to the torch?

it is NOT this one:
http://www.mrtool.net/machine.aspx?listing=M1079 though its somewhat
similar.

Is this something I want to futz with? Is it suitible for doing small
gun parts and such? The last Tig I used was a Miller 2500..and this
is a much different kettle of fish.

Ill be looking at it again sometime later this week. Any information
as to what this critter is good for, would be appreciated.

Some may decry the impeachment of William Jefferson Clinton as a national trauma,
but not humorist P.J. O'Rourke, who thinks the proceedings are a win-win situation
-- and grand entertainment to boot.
Mr. O'Rourke, writing in the latest issue of the Weekly Standard, acknowledges that
"some earnest souls have gone so far as to aver that impeachment
has distracted President Clinton from ... raising taxes, destroying health care,
appointing 1960s bakeheads to high political office, soliciting felonious campaign contributions,
hanging friends out to dry for Arkansas real estate frauds, giving missile secrets to the Chinese,
taking credit for the benefits of a free market about which he knows little and cares less,
using U.S. military forces as fig leaves for domestic scandals and au pairs for the U.N.,
leading foreign policy back into the flea circus of Jimmy Carterism, having phone sex,
groping patronage seekers, and snapping the elastic on the underpants of psychologically
disturbed school-age White House interns entrusted with the task of delivering high-level government pizza."
Ouch. Tell us what you really think, P.J.
"No matter what, Bill," Mr.O'Rourke concludes,
"your girlfriend's ugly, your wife hates you, and your dog can't hunt."

I occasionally use a 'L-Tec' micro-plasma welder for joining small section
stainless steel parts. I think this machine is very similar to the Linde
machine you describe. Now, I am NO welder but with a bit of practise I have
managed to join wires down to 0.6mm ( about .024" ). The gases used are
Argon and a mixture of Argon and Hydrogen at about 7%, although this can
vary depending on the work you're doing. It is only good for stainless
steel, titanium and copper. The one I use is a noisy unit with the cooling
pump running and interferes with any radio ( and possibly TVs nearby ).
Quite honestly, while welding is stronger than brazing/soldering, I think I
could do just about everything needed with good quality hard solder. The
main reason I use the plasma welder is for chemical requirements where I
cant introduce a second metal ( the solder ) to the work.

Hope this is useful,
Dean.





Left wing loonies believe in freedom of expression - as long as you agree
with them. If you dont, then they will put their point across with a
megaphone jambed into your ear. This tends to persuade me not to agree
anyway.

I worked at a place near 20 years ago, that used these (I don't
recall if they where Linde, however) for fusing together thermocouple
wires for use as temp sensors on jet engines. It was described to me
as "being like a small heli-arc welder. Mostly pretty tiny stuff, and
the "purity" of the joint was important, ie minimal contamination to
form secondary t/c junctions. I never ran one, but they where way up
there on the "Gee-Whiz-cool" factor.

I can't advise as to wether or not you want it, but I would find it
hard to resist. Though I'm not sure what I might use such a thing
for...

IIRC, they were used to weld titanium aircraft components.

Gunner --

Looks like it might be similar to units made by PUC and ABI intended
for jewelry and precision small-parts welding use. If you don't wind
up wanting it, I might be interested -- have always wanted an ABI
Pulse-3, but balked at the price!

Cool, and relatively small/light. I don't know what the resale value
would be if you wanted to sell it, or what exactly I'd use it for
(thermocouple probes are one example, but 15A is pretty low- would
that weld a 1/4" 316SS tube?), but I'd be tempted to grab it anyway if
the "price" is low enough.

LOL...I dont remember the thread, the device nor the replies. I run
across a lot of my posts from before 2009...that are new to me. That
stroke was not a fun thing.
