mixos Posted April 7, 2004 Report Posted April 7, 2004 Heats fast, cools fastThe Cold Heat Soldering Tool is a cordless tool that heats quickly and cools down nearly as fast. It creates the heat right in the proprietary tip material, making the tool 20 times more efficient than the average conventional soldering iron. The tip reaches 500 F in less than 1 second for many types of joints and cools to the touch in 1-5 seconds so you can put it away Quote
ginji Posted May 31, 2004 Report Posted May 31, 2004 thats cool, but i like my weller better :P Quote
surajbarkale Posted September 13, 2004 Report Posted September 13, 2004 This is a good tool to show off to friends but i don't think i can use it. Man if i can't feel the heat coming off my solder gun i might doze on the veroboard itself :D Quote
MP Posted September 19, 2004 Report Posted September 19, 2004 I have been trying out this device to see what comments I could add about it. I only have the larger tip, so I cannot get into the tight spots with mine, but it looks like the tip touching the solder or copper completes a connection and causes the tip to get hot like a little welder. Then when you remove it, the connection is lost and it immediately shuts down and cools off. With a little practice, I think I could do pretty good on larger circuits. My only concerns are that I see a little spark when the tip is making connection. I am not so sure you would be able to use such a tool with static sensitive devices. Suraj, perhaps the spark will help keep you awake ;DMP Quote
surajbarkale Posted September 23, 2004 Report Posted September 23, 2004 Now that you are mentioning the sparks, i have a story to tell ;). Some years ago in a magazine named Electronics For You (in India) i read an article. It was about making a solder gun from a normal wooden pencil. The recipe was like this. You will need a 12V/1A DC power supply (filtering is not required). Take a wooden pencil attach one terminal of the power supply to one end of the pencil (to the lead inside it). And attach other terminal of power supply to the solder metal. Now trim the other end of the pencil to suit your needs. When you connect that end to the solder metal, it melts. I tried it out it was working fine until i accidently burned one BC547 by touchin base wth one lead & collector with another ;D . I stopped using it at last when i fried some more parts ;D So if it sparks take care Quote
dicky Posted October 24, 2004 Report Posted October 24, 2004 Yeh!..I like my Weller too..One thing to know though..Some brands of resin core solder are not 60/40..they are 50/50 in make-up [tin/lead]... this leads to more heat required and sometimes ruined PCBs [ watch the cost of tin on the stock market ]...Dicky Quote
Jshwaa Posted March 6, 2005 Report Posted March 6, 2005 Anyone got a hunch on how it works? I'm guessing it uses some sort of ultra-sonic magnetic field which creates a vibration in the solder which induces friction and heat. Kind of like a pin-pointed microwave. Quote
MP Posted March 7, 2005 Report Posted March 7, 2005 Here is my hunch:It is more like a short circuit. There is a split in the tip and when you have a connection by the copper across the split, I think you are completing this connection which causes a short and thus gives you a high current. There is a spark like when you have a short.I have only used mine a few times to see how it functions, but I imagine that the AAA batteries will not have a very long life if you use it a lot.MP Quote

mrohler Posted July 11, 2005 Report Posted July 11, 2005 yeah it puts out a small voltage/current because when you solder led's with it and touch both leads it will light up. Quote
audioguru Posted July 11, 2005 Report Posted July 11, 2005 It is not a welder, the tip is a low value resistor with two contacts. Bridge the contacts with something conductive and the tip heats.If it has enough voltage to light an LED and it has enough current to get hot, then it will light-up the base-emitter or base-collector junction of a transistor too. ;D Quote
jstevenperry Posted December 25, 2005 Report Posted December 25, 2005 I've heard that it takes a fair bit of pressure to activate the mechanism, which makes it difficult to use for some delicate operations. Quote
logan_dslasher Posted February 18, 2006 Report Posted February 18, 2006 i'm puzzled how it can heat and cool that fast! Quote
gogo2520 Posted February 18, 2006 Report Posted February 18, 2006 I have one and ya it looks pretty. I don't use it because it sucks up battires fast. and you really got to fanagel around with it to get it to solder. Its like a test to see if its going to work this time or not. Like I said I got one, its on my bench or shelf someware and it sure looks pretty. Good thing I got a weller too ;D have fun gogo Quote
logan_dslasher Posted February 18, 2006 Report Posted February 18, 2006 its on my bench or shelf someware sounds like your not using it anymore, and probably will not! can you ship it to me then? ;D ehehe.. i once heard that there is a soldering iron that uses hot air to melt the lead? something like that exists? Quote
gogo2520 Posted February 19, 2006 Report Posted February 19, 2006 Hi loganYou mean something like thishttp://www.web-tronics.com/esdsacpucore.html I don't have one of these yet. But it would be nice to have.You don't want the cold soldering Tool I got, I broke one tip trying to make it work and the other on is the big one. It take 4 aa battires to get it to work and you might get 5 good solder joints out of it befor you have change batteries. gogo Quote
logan_dslasher Posted February 19, 2006 Report Posted February 19, 2006 that was cool! i mean hot! ehehe.. one of my thesis proposal ideas was a soldering iron with a built-in desoldering pump.. it was just too crazy.. :P Quote
jughead Posted March 6, 2006 Report Posted March 6, 2006 ok i got this thing as a gift its pretty cool!but downside...its finiky...you have to touch the tip just rightalso you dont tin the thing...weird...it seems sort of bogus 2 memy theory of operation:i thinks its a dc-dc converer like the ones found powering the light in your scanner...a astable multiviborator clock goes through a stepup transformer but with some sort of regulator for the thing so it dosent arc or put a hole thru your fingeri have cut pcbs by using the arc from a scanners dc-dc converterand put holes thru the tips of my fingers... also melted solder and lit a cigarette i cant do anzthing with it its weirdby the way it takes 4 AA batteries and they heat up terriblelymy opinion... it makes a better flashlight then it does a soldering iron...i took a look inside...1 little surface mount board... the main chipis a ....I don't know! you tell me!they grinded the ic # off!!!they really must not want this piece of junk copied!it could have been worsei might have had to pay for it... nope i got it as a gift...

Mac L Posted March 9, 2006 Report Posted March 9, 2006 Is there a patent # for the device? If so, the documents at the patent office should clarify what's up. Or is it not fair to go to the answer book? Quote
rybitski Posted May 9, 2006 Report Posted May 9, 2006 I was thinking about getting one of these, but I have just changed my mind... Quote
MP Posted May 14, 2006 Report Posted May 14, 2006 Is there a patent # for the device? If so, the documents at the patent office should clarify what's up. Or is it not fair to go to the answer book?How does one go about looking through patents? Is there a URL link that you know? I know that it is public knowledge and that you could go to the patent office to look through items by category, but I have not seen an internet link. Was just wondering if anyone knew.MP Quote
kid_kv Posted May 15, 2006 Report Posted May 15, 2006 since you can't look for it this gos to the u.s patent web site but NOT all things have a patent on themhttp://www.uspto.gov/patft/index.html Quote
MP Posted May 15, 2006 Report Posted May 15, 2006 Yes, I am aware many things do not carry a patent. Thanks for the link.Mac L: Thanks for bringing up the subject of patents. "Patents in general" might be an interesting discussion for a new topic.MP Quote
jpknhtp Posted June 9, 2006 Report Posted June 9, 2006 A few things to note. I have owned one of these and returned it days later. It does work but it is very touchy. You have to get the tip just right on the joint for it to heat up and most the time you do have to put some pressure on it. The problem is the instruction book specifically says do not press down on the tip or you'll break it. I sucks batteries way to fast. This device is only good to keep in a glove box for and emergency solder needs, that way the batteries have a chance to recover a bit from it's last use. The thing doesn't heat and cool as fast as it says. It heats up in a short time (20secs) but the longer it's on the longer it takes to cool. It normally takes awhile to heat up so by the time you soldered your joint the thing is to hot to touch for the next minute ..... not seconds. I have looked over the patent and the patent covers the idea and tip not the circuit that drives it, it might be under another patent. The thing does put off sparks when you first touch a solder joint. Melting an already existing solder joint is a lot easier then making a new one. When trying to make a new joint if you start the tool on the solder pad you will turn the pad red hot and melt it off the board, if you start it on the solder then when it starts to melt you lose the connection between the tips and it stops heating. If you get clumsy with the tip and it touches two pads at once you will send a bad amount of current through your circuit. My suggestion. Save your money. Quote
