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?
