Then I guess that it would not be very suitable for the industry that
much... May the experts correct me here if I'm wrong.
From the courses I remember, in order to get a good solder joint, both parts
to be soldered have to be preheated before soldering, therefore we apply
heat to both parts before applying the solder. With that in mind and the
fact that this technology requiring electrodes to be shorted to generate
heat, it must be tricky to preheat both parts appropriatly.
Another thing bugs me. If this tool gets so hot so fast, I imagine that
when the contact is made there must be a pretty good current surge. Can't
that affect reliability of sensitive components?

They do heat up in seconds and cool in the same time frame. They are an arc
system that requires that the 2 electrode tip contact the metal to bridge
the electrodes and generate heat. The electrodes are .070" wide and spaced
.025". This requires a large area for the contact to occur and is somewhat
difficult to have a continuous intimate contact to the pad and/or lead. The
tip is a very soft graphite material that breaks with a very light touch.
The tendency is the press down to gain contact and this breaks the probe
tips making it even r to get contact.
The technology appears to be heading in the right direction, but the
development of a more robust probe set, with smaller contacts is needed.
For now the unit we purchased sits in the tool box, luckily the cost was low
and the risk of testing this unit not an issue. We ordered in May 2004 and
received the unit on Oct 15 2004.

Subject: [TN] Ok... where's the catch?
Lately I've been ask a question about a revolutionnary soldering iron that
can generate heat in seconds and return almost instantenously to room temp.
Tech around here ask if this is safe, how it works and so on. I made a
search on the net on the product (cold heat) and could not get a lot of info
but that it works.
Did any one try it? I believe that there must be a catch with this. Any
comments?
