I've seen this as well, and am debating whether or not I should get it. Although, in their FAQs section:
Quote:
2. Are there kinds of soldering jobs for which the tool is not recommended?
We do not recommend it for soldering of large metallic components that require a lot of heat transfer or for soldering sensitive electronic components that may be damaged by fast-rising temperatures or high electrical current. (Momentary high-amperage current will be created during active soldering.)
I would like to know if it's safe to use on the console motherboards. If someone has personal experience in using it for installs/repair, and can vouch that it does not affect the motherboard components, please let me know.
I'm 90% sure I'm going to buy it, though. It will help if I need to do any other electronic installs/repair, such as car audio.

let me know how well this thing works, if it's good i'll order 20 of them for work. the only thing i'm leary about is where it sayd it heats to 500F in 1 second. I need it to be more like 650-700F

The main site for this is at
http://www.coldheattools.com
In the FAQ, it says:
Quote:
6. How hot does the tool get?
It depends on the size of the joint. For a small joint, the tip may reach 800ºF in less than one second and may exceed 1,000ºF. For large joints, the temperature will be lower, but in all cases the temperature necessary to solder will be reached within a few seconds. We do not recommend applying the tip to a small joint for longer than a few seconds, as the temperature may keep rising.
There's also a number to reach them at for bulk orders.
As for reviews, I'd suggest looking around the Internet. There are some on amazon.com's site, search under "Cold Heat Soldering Tool". Here are some I'm concerned about:
Quote:
This tool generates heat in a joint by running a current through it (like a toaster does). This can be lethal to solid state components such as transistors and integrated circuits. Even work on automotive wiring may be risky, as most modern vehicles are crammed with computers that are susceptible to excess current.
and
Quote:
Now, there is one negative for this tool and I guess this might be a biggie. The tip of the soldering tool is two pieces and it only gets hot when something metal completes the circuit between the two halves. So for really small places where you need to solder, this tool might not work well. It also can be a bit clumsy to work with because of this.

Unfortunately I must say we are all a bit suckered in by this one. It seems like such a brilliant idea and of course the question is does it work. Well my suggestion to you guys is stick to your tempature controlled soldering guns with the nice pointed tips for any kind of electronic work like mother boards or using it to solder your componets. As far as using it to solder wires and such it would be a great tool, after all look closely to the commercial that had us all pissing in our pants the first time through watching it (for us experienced solder gun users anyhow.
Howdy!

In reply, My question follows:
Was the above quote given by the manufacture of the "Cold Heat" solder iron? Even if the iron uses electrical current at the tip to produce heat, it would NOT be a hazard to sensitive circuitry unless somehow the user could complete a path for the current to pass through the circuit and then back to the internal power supply. If this iron does this by design, then I have got to have one just to tear it apart to see how they have achieved such an impossible feat. This iron, unless it builds some large static charge at it's tip, will not harm even the most delicate cmos circuitry. OHM's law doesn't make it possible for this to happen. I think I'll buy one and hope it will solder as I am tired of fooling with the $100.00 gas models that work fine for a few weeks, then die.

It sounds like resistance soldering to me and should be safe for electronics they have been using it for years on model railroads with dcc systems which have digital components such as ic chips.

WRONG...
This device has two pins on its tip... one from the plus side of the 6 volt power supply and one from the minus side of this 4 A-cell battery pack... It heats by passing high current through what you touch it to... Now if you touch this tip to a PCB so that one pin hits the leg of a component and the other hits the solder pad on the PCB you will place 6 volts with high available current in series with that circuit... depending on the component and the width of the trace involved you could cause plenty damage with this device... This thing should NOT be used when any electronic components are involved...

Even if the iron has a positive and negative contact at the tip (to produce heat), which I can believe it does, the current (electron flow) will take the shortest path(the path of least resistance), which happens to be from the negative contact of the tip of the iron, back to the positive contact of the tip of the iron. Given this fact, no electrical damage would occur from the flow of electrons that produces the heat required to melt the solder. This iron will not pass current through the circuitry unless it is intentionally made to do so. Furthermore, all TTL circuitry is designed to operate on +5Vdc and sometimes at greater voltages. A +6Vdc power source has too low of a potiental to cause damage to even the most sensitive IC. The iron may burn a hole through to China and lightning may toast cmos, but this iron will not, by design, electrically destroy even the most delicate electronic circuit.

Not to bash any comments made against this statement, but there is a very good possibility of harming circuits. First of heat is the main issue, there is no way to control how hot it gets. Second the current going through the two tips can most certainly destroy sensitive components, the ampherage is deff higher than the allowable amount through any component. And any accidental connection from both sides of the tip to chips or ic because the wires are very close would most certainly damage it!
Howdy!

Well yes, heat will destroy things if you are not careful. As for damaging components with electrical current produced by this iron??? I guess this discussion is best left with those who understand the physic's of the atom! I'm sorry, I thought I could help someone understand that this iron IS SAFE TO USE. I guess those of us that understand this fact will enjoy using it.

Amperage is the amount of power available and voltage is the potential "push" of the electrons. If you have a 6-volt device that normally has .001 amps going to it you can send 6 volts and 1000 amps to it and it won't matter. Try hooking 8 AA batteries up to a 12v light bulb, then hooking up a car battery. Both will yield the same result but the car battery exceeds the AAs by hundreds of amps. Also, Kirchoffs laws tell us that adding current to a single pole does nothing. You could put 100,000 volts on one end of an NPN transistor and not harm it because there would be no way to complete the circuit. The split tip sends current out on one end and the has polarization on the other the will take in EXACTLY the same amount of voltage as was pumped out of the positive lead. The only damage I can see happening would be heat damage and maybe somehow bridging two poles on an IC with the tip.

I bought one. It didn't work. Draw your own conclusion. I asked for a new one and instead they refunded my money. Does anyone have one that works?
The End

I ordered two in July and have yet to receive them.
The keep telling me they shipped in August.
What a crock...and after reading some of these posts outlining the fact that they don't work, I would reccomend anyone that has bought one and hasn't recieved it, to cancel the order and go to Radio Shak to buy a real iron.
Contacting that company is the biggest hassle.
Again...DO NOT BUY ONE OF THESE PIECES OF JUNK!!!

In this review
http://www.10news.com/evening/3788849/detail.html
it was noted that this iron produces an ark at the two points.
This is a small device, and there is no way to provide the necessary current with 4 AA batteries using a linear design approach. What they would do is use a switching or "bucking" circuit to increase the current and power.

Just got mine today. Couldn't resist pulling out the meter on this one. Here's all I've found..
At the tip, we had 5.28v at barely 2amps. All in all, I cannot see this damaging electronic components unless you're using a jumperwire to extend the path of the current across your component. If you're doing that, you might as well just use 240v and have some fun with it...

First, you shouldn't criticize people if you don't understand electricity yourself. Amperage is not power, wattage is power. Amperage is the measurement of electron flow (comparable to flow in liquid terms) through a wire or other path. Voltage is potential, and is comparable to pressure in fluid terms. Power (watts) is a calculated value that is calculated using ohm's law. For DC circuits, it is merely P=IV=V^2/R= I^2*R where P is power in watts, I is current in amps, V is voltage in volts and R is the resistance in ohms. In order to have any current, there must be a path from the potential to a lower potential (for example ground). You don't "send" voltage, you apply voltage. You can't send a device that requires .001 amp 1000 amps. You can attach a device that requires .001 amps to a source that is capable of supplying 1000 amps. If you applied a 100,000 Volt source that had large current capacity to an npn transistor, there would be arcing between the leads, thus damaging the transistor. I think what you say in the last sentence is exactly what the guy you are criticizing was saying - if you touch two leads of a chip with this piece of crap's tip, it will pass current through the chip's pathways, and damage the chip.
