Welding Stainless with TACK II


#1

I really need help on this. I keep hearing that TACK is just for tack
parts before soldering but some people say that TACK II can be used
as a regular spot welder and will leave a permanet joint as well. Does
someone can tell me the real thing on this?

I trying to weld very small parts of 316L stainless steel. one of the
part is a thin strip of .007" thick and the other is a square flat
plate .100" long X .065" high.

I need to know if TACK II can permanent weld these two tiny parts?

Can I get a real strong weld with the TACk II ?

Can I use silver brazing between the parts using the TACk II to get
an stronger joint?

Does anyone has a used TACK II that want to sell?

I appreciate any help from you guys…

Yes the “Tack II” welds both as a tack for soldering & at higher
settings will make a permanent weld ( I now use it rather than my
"Sparkie" most of the time. Their current promo cd shows some VERY
interesting granulation work done with the “Tack II” have yet to try
it but the possibility of granulating around something like bezel of
an already set opal has incredible potential!

Can I use flux to improve oxidation when using tack II?.

How can we make an stronger joint using the tack II?

do you think by aplying more heat (more volt) the two parts with melt
more material bewteen them and have a better joint?

Is the weld done withing a second or less?

Luis, The tack II will do exactly what you are asking. The Technical
Support team at Rio recently did some welding project for one of the
research hospitals here in Albuquerque. The project was to weld
stainless steel wire .005" in diameter to some 30 gauge platinum
sheet which was approx. 5mm square. The Tack II was able to weld
this wire in 2 spots on each sheet with very good results. These had
to be clean welds as they were to be assembled and used as electrodes
for implants in the brain for stroke victims. The welds were as
permanent as a wire about half the diameter of a hair could be. We
tested and were able to weld some 80 of these little electrodes with
great success. The research facility ended up purchasing the
machine.

Ideally, a laser would be able to do this in much less time and with
greater accuracy. The machine was set almost as low as the machine
goes. If it wasn’t set this low, we literally blew up the wire.
Featuring would also be another advantage with the laser. Once the
correct settings on the laser are established, it would seem that
welding several hundred per day would be very easy. Setting up the
tiny parts would take the longest. Magnification is also a must for
these type of parts. A microscope setup would be ideal as you could
see what you are doing.

The answer to your question is yes. The Tack II will do the job.
We found that the Tack III and other tack welders did not perform as
well and did not give as consistent results with our trial project.
