Its execution is horrible, however. While the tip does heat up and cool down in about 5 seconds, the longer you use the ColdHeat the longer it takes for the tip to cool down. The tips wear quickly, and prone to breaking, are large making detail work hard if not impossible , and expensive, and the overall technology behind how the ColdHeat works could potentially kill any ICs you work on.
Additional note: ColdHeat has struck a licensing deal with Weller, a well-known and respected soldering iron manufacturer. Weller will begin selling the ColdHeat under the Weller brand name. Keep in mind that Weller does not manufacture this version of the ColdHeat; as sold by Weller, it's just a normal ColdHeat that's been rebadged.
So, don't buy the Weller version thinking it'll be better -- it's not. The Weller iron is actually ColdHeat's new "Pro" model, not the model reviewed here. Please see Weller's post in the comments below.
ColdHeat soldering iron - user experience. Wow thanks! I've always found it a really cool concept but thought it was a scam. Thanks for proving it. He did not prove it was a scam, just that it has some flaws that make it not suitable for certain precision work. It works as advertised and was never advertised as a replacement for the high dollar Weller type irons with the fine point tips for doing work on. I bought one because I thought it would be useful for "in a pinch" situations. But the Cold Heat requires much more time and patience to complete a simple project than a basic soldering iron.
The tip is fragile and imprecise. If you break it, you can use some finer grit sand paper to reshape it. Thank you for the positive comments about the Weller brand. I would like to point out that The Cold Heat tool in your review is the "Classic" model. The Weller model is the new "Pro" model. The Pro model is larger and more powerful than the Classic model, although it still employs the same basic technology including the Split Tip.
I would like to make some comments on your review, and point out the differences between the original model and the new Pro model:. The Pro model is larger and more robust than the original Classic tool. The Pro version has an LED work light located above the tip, which addresses one of your concerns. The instructions included with the Pro tool go to great lengths to stress the delicacy of the tip. There is no need to apply pressure like you do with conventional soldering.
Regarding arcing, we do not represent the tool as ESD safe. In fact, our instructions warn against using it on circuit boards. As with most product choices, there are trade-offs to be considered. The Cold Heat Pro offers the ultimate in convenience and portability, and will give reliable performance if used as instructed. I had no idea this thing works by passing current through what you're trying to solder! That scares me. I bought one not knowing that. I want to fix my zen micro, my dvd player, and my eventually I have one as well and can't take it back to the store.
I have tried it on 3 different projects, yesterday being the latest. I haven't even gotten it to melt the solder yet. I have tried two different sets of batteries and at least a half hour of playing with it for each time with no success at all. I hope radio shack will take it back. Somehow I don't think you'll be getting your money back.
As the one who first posted a thread about this tool , I still think that it is like most any purpose built tool. I would absolutley buy and use one for large jobs, like soldering larger guage wire or automotive type work. I think if you are not using it for electronics, you are fine.
For soldering power cords and fixing PSU's and such, I think it is fine. Cold heat soldering irons are somewhat different as batteries power them. Also, unlike traditional soldering irons, they heat up pretty fast and cool off almost instantly.
Hyperion Industries using their Coldheat Trademark exclusively produces the soldering iron. It is the main feature that makes traditional soldering irons different from cold heat irons.
Electric irons use a resistance heating unit similar to what is used in toasters and hair dryers. An electrical current passes through the heating unit, and electrical resistance makes the unit hot.
It is this process that makes the soldering iron take time to heat up and cool off. Usually, the heating unit warms the tip by transferring energy. The molecules start moving faster and faster as the system heats up, and when cooling off, the molecules begin to slow down. The time the bit takes to cool off depends on emissivity a measure of how efficiently a substance transfers heat to the surrounding.
Materials used to make soldering iron tips include nickel, copper, and chrome, and they have low emissivity. It explains the long time it takes for traditional soldering irons to cool off. Cold heat soldering irons, on the other hand, use the heating system used on resistance soldering irons. The irons use two probes that look like tweezers, rods, or pliers to pass current through the solder. The solder then heats up fast because of the resistance to the current through the probes.
The other difference lies in the construction of the tip. Show More Show Less. Any Condition Any Condition. See all 13 - All listings for this product. Ratings and Reviews Write a review.
