I'm not familiar with a Tig welder. How does it compare with a
The PUK units are essentially desktop TIG welders, they use the same
technology and concept. The major difference (after viewing the
online stuff) is that the PUK operates more like a spot (tack) welder
(very similar to how a laser operates), vs. a TIG welder that can
hold a continious arc between the electrode and work piece, achieving
greater penetration and continuity of the weld. Not to mention, you
can do much larger items with a dedicated TIG unit.
Ive just begun my venture into using a TIG welder for my
applications, and have been in communication with Kevin on it (thanks
Kev!). I have a different setup than Kevins, his is a traditional TIG
machine, the unit Im using is a Plasma Arc Welder or PAW. They both
operate on the same principal, creating an arc between the tungeston
electrode and the work piece, but with PAW, there are two gasses
used. The shielding gas is similar to a standard TIG unit, but the
second gas is a gas that flows around the tungsten electorde and the
arc is carried thru that gas, plasmating the gas to carry the arc.
The major advantage of this setup is a highly controlled arc, and
greater penetration, especially on tiny parts, in addition it keeps
the electrode away from the work piece and contamination of the
electrode is next to impossible.
For price difference, TIG is about 1/2 the cost of PAW, and the high
end PUK3 unit, falls in between the two. Fortunately for me, there is
ebay, so it didnt cost me a whole lot to jump in the game…all
As stated, I have just gotten my setup running as of today. Learning
how to make this work for my applications is just going to take time,
but Ill be joining Kev with the development reports as they come in.
