content: Alright, so this is something I am guessing has happened to everyone, but hey, maybe a couple people have gotten through life so far without ever grabbing the hot end of a soldering iron.I know it's happened to me three times so far, possibly a couple more that I can't remember, but it always leaves a familiar feeling blister that is sure to form. Last time for me was a few months ago when I was fixing my a cheap laminator I got, I was distracted, listening to music, multitasking, and grabbed the hot end, it was not fun, and I couldn't believe I did it, it seems like such a rookie mistake.At least I got it on video since I was recording the process, unfortunately (or perhaps fortunately) my channel isn't popular so I not many people laughed at my noobery.So, when was the last time you burned your hand with a soldering iron? What were the circumstances?Another fun (but much rarer I think) situation is when a ball of hot solder flings off or drops leaving a round indent in your skin for a while. That's only ever happened to me once.

content: Quote from: TheBorg on January 30, 2014, 07:00:05 amOh wow lol, that's certainly something.I get plenty of hot glue burns (well, not burns but just a fair bit of pain) using high temp hot glue, always from using my fingers to adjust the glue, scrape it away from where I don't want it or trimming edges, so it's all self injury, but yet I still do it. I do make sure it cools a bit though.

content: I have grabbed the wrong end of the iron when i had a plug in one. something pulled on the cord or the table shifted and pulled it and somehow the iron turned sideways. It was just one a little wire stand so i reached over and grabbed it and it hurt a lot. Also i have done the same thing with hot glue when it runs off the side of what i am gluing or something and i try to wipe it off with my finger.

content: Quote from: XOIIO on January 30, 2014, 07:03:33 amYeah... I think it was freshman year in high school. Needless to say I've respected the hot glue gun ever since.As for grabbing a soldering iron, I think the worst I've done is held the iron and tried to do something else (switch playlists or something) and ended up burning myself or some nearby plastic. Lessons learnedI did burn myself a lot more with the fire-starter iron and wire stand, as houdini says. It's certainly easier to do that...

content: I have had the tip unscrew and land on my arm, gas tips actually degrade to a point where they snapped off and land on my chest, and other people flick abnormally large bits off solder on my various body, and carelessly swiped it across bits of my hands while soldering things (and burnt my self stupid amounts with a gas iron in my first 6 months of using one))but through all of this i have never actually grabbed the hot end, i think having a enclosed stand style iron for my first probably helped a large amount with this. if your in a quarter of a million dollar bus and the soldering iron is in mid flight to the floor, i let it fall, its less painful to replace carpet than it is to replace skin,

content: You guys need to use a stand.Not just to avoid grabbing the wrong end, but also to avoid accidents where the iron shifts and scars stuff and wires.Not that I do not know the feeling of hot irons, but most of my burns were the shape of resistors or leads that I felt I needed to hold on to while the solder solidified. 3rd hands are so difficult to work with sometimes.PS: does not even need to be an expensive stand: An old glass jar is already better then letting your iron float all over and touch stuff.

content: Quote from: cybermaus on January 30, 2014, 07:32:43 amYeah, my earlier burns were without a stand, and just a radio shack plug right in iron. I didn't get an adjustable iron until a year or so ago, man was it a nice change going from that to a second hand hakko 936. The most recent burn was just epic failure though.I know what you mean about helping hands though, maybe it was because I only got radio shack ones but you have to struggle to get them just right, and eventually the stupid little clamps get loose and fall off, and you can't solder them in place, and they never came with three hands, only two :/Here is that video if you are interested, skip to 35:40 or so.(not sure how to embed here)edit: ah, it embeds for you.

content: I never used or missed a third hand. I use my thumb and second finger as one "clamp" and middelfinger and 4th finger as the second "clamp".I'm in the "Lucky" circumstance that I do not feel burns so I have to be extra carefull. However the chance to burn is rather small. The solder irons are in their stands so it is impossible to grab the wrong end.But looking at the way you tear that poor laminator down I'm not really supprised you burn your self. (only looked a few minutes, I think you will have to change a lot if you want more viewers)

After that I bought a cheap soldering iron stand and nowadays I use a proper soldering station. Had plenty of hot solder balls flying around and hitting my fingers though. Once I managed to touch the tip with my thumb so now I have a nice little scar as a reminder

content: I really don't get how anyone can 'grab the wrong end' of an iron.It's not like the ends look the same in any way.Slipping with the iron and touching it to skin on the other hand, sure, i've done that many times.Oh, and on the subject of hot glue burns.. The trick with hot glue is really simple.If you get it on your skin, RUB IT IN!!Seriously, rubbing it in massively spreads out the surface area and it cools down to non-burn temp almost instantly.It still hurts but doesn'tkeephurting.Once you start doing this you will never get burnt with hot glue again.

content: Never directly burnt skin on a soldering iron, but I have burned my fingernail when I first started because I held the soldering iron wrong (holding board next to iron with flat finger...) The funny thing is, since fingernails don't have pain receptors, you don't notice until you smell burning keratin, which smells like burning hair. Then you see the hole in the fingernail.

content: I voted yes but i don't think I've actually ever literally grabbed the wrong end of the iron, just a few mishaps over the years where I've made contact with the wrong end. Never at the bench though, always in the field soldering wires sticking out a wall or under a bench etc. requiring three or more hands sometimes. (I've been a security / audio-visual field technician for the past 10 years).The worst soldering injury i can remember though was not from the iron, but from a large blob of solder landing on my leg while i was in a difficult position (under a supermarket checkout counter). I couldn't flick it off and i made it all the way through the skin. I still have the scar.

Careless, not looking, it had moved due to the weight of the cord, etc. Never again.But the shorts mistake is so easy. 'It's a hot day, I'll be careful not to drop solder splatters...'At least I've learned never to arc weld while wearing sneakers.

content: Can't say I've ever grabbed it. Brushed many times. And I've pretty much built up a tolerance for holding leads/wick while soldering - though the key is knowing exactly how long the iron can touch it before it becomes too hot. If you squeeze harder you get a bit more time, as the heat distributes more thoroughly.

Nylon woven sneakers and synthetic socks on the other hand, make a melted mess that retains molten steel very well. Trust me on this.Oh hey! I just remembered a really funny one. I was up a step ladder using a hot air gun while doing some PVC ductwork installation in the ceiling during house construction. Hot air gun used for bending the ducts, so it was set on 'hottest'. I'd momentarily rested the hot air gun on the top of the stepladder. It slipped off, and swung on the cord. The very hot round metal end of the gun made a hard landing on my bare calf. Shorts again.For a long time I had a rather cool looking new-moon shaped semicircular scar.

content: I can honestly say that I have never grabbed the wrong end of a soldering iron. I always wear shorts here in Florida so, of course, I regularly drop molten solder on my legs. I used to have a Radio Shack desoldering iron that I have scars on my arms from touching it while reaching over it. I also use a small butane torch with a hot air attachment for small heat shrink tubing that I have laid my arm on. I have a very high tolerance for pain so I typically hear the sizzle before feeling anything. I do like the fact that there is no blood as the wound is instantly cauterized. When we were remodeling the second bathroom, I was sitting on the floor using a hot air gun to loosen the glue from the old linoleum floor when I laid it down on my leg-see above with the shorts wearing in Florida thing. I jumped and so did my wife. There was a point a few years ago where I was burning myself so much soldering that my wife got me a prescription for silvadene, which is a burn treatment medication. Ironically, she ended up the first one to use it

content: Managed to pick up an iron which Ithoughtwas off by the hot end when I was a teenager and managed to brush the desolder gun briefly against my knuckle recently but no major burns from soldering. Hot fingers and the occasional "ouch" don't really count.Potentially the worst burn was actually when I was doing some plumbing - I'd turned the butane torch off but managed to knock it back against my finger almost immediately. I wound up with the curved edge of the burner making a neat pucnhed out hole about 2mm deep by 1mm wide and maybe 1cm long. Of course as it was a full thinkness burn it didn't hurt.Remember, the worst burns aren't painful because they kill the nerve endings in the skin rather than just damage them (which is why burns hurt in the first place).

I accidentally rested the iron against the cap without noticing. I noticed an odd smell, then POP. The cap vented. Fortunately it didn't spray out like a volcano, but I could still smell the electrolyte.Fortunately I had a spare. I think there's still a stain on the iron though, from the burning plastic wrapper.

I was thinking of buying their irons, so I picked one up and was looking at how the element went in... then I got that sizzle and shooting pain and realized it was turned on and I had just grabbed it firmly with my whole hand.I quickly dropped it and then put it back into the stand. The salesman was just standing there dumbfounded, and he said "why would you grab it by the element?"I looked back at him with the same look and said "why would you have all of these turned on?".He didn't get it... but to this day, I still don't get why on earth you would have a row of soldering irons all turned on. It's not like they were doing demonstrations or you could use the iron to test out. It was just a bunch of irons on a table with the handpieces out front - turned on. Dumbest. Idea. Ever.

Burnt myself several times as a kid by not watching what I was doing and getting the other hand in the way which is just as dumb and warrants a yes vote.My last burn was grabbing a board with a big copper plane that I'd just hot air reworked.

content: I remember as an elementary student, I was just getting into electronics, and loved those little Velleman kits I could buy at Fry's. One time, I was using my weller fire cracker, and put it on the stand. Not thinking, I reached over to get it, and I grabbed the tip firmly. Very soon something along the lines of YYEEEOOOOOWWWW and a few Chinese expletives were shooting through the house. I remember throwing the fucking iron against the wall and looking at the big, soldering iron shaped imprint in my palm. Father was not pleased.

content: It wasn't a soldering iron but a big duplexer. About 14kg of metal and there was one very awkward solder joint on it that could only be made by putting the unit on a hot plate and bringing it up to temp. a technician was just finishing the joint and asked if I could inspect it. I peered in, but the light wasn't right, so i picked up this 14kg block to angle it better to the lights. I'd just got a clear view of the joint and could see it was good when one part of my brain told the other part of my brain that it was experiencing pain from the fingers and that something should be done. I put it down gently, otherwise the joint would have failed and we'd have had to start over.i had no feeling in my fingertips for a while.

I burnt my self so many times I went to school with burns all over my hands, and I couldn't write properly!no-one else needed to use a soldering iron, so they didn't feel the pain!Oh there the days when you had a plug in soldering iron without a stand!I have also burn't my-self using a hot glue gun. I was up-side down gluing wires in our boat, and a bit of glue dripped on my forehead! It was a great start to my holiday, a burn mark on my forehead!

content: Quote from: vk6zgo on February 01, 2014, 07:11:36 amOh that's not true at all!You know those big dropsaw-like abrasive-wheel cut off machines? Used for sawing through thick bits of steel quickly?They have a simple clamping setup, to hold the workpiece. Much like a vice.Which works fine for holding rectangular and round bars, but one time when cutting a piece of Dexion shelving L-beam, I made the rookie mistake of clamping it like this: Wheel direction ---> ]L[The problem is Dexion L-beam has a radius corner. So it didn't take much to work it loose from the clamp jaws, especially since the wheel starts cutting from the top down.The thing with high speed power tools, is if you got it right nothing bad happens, but if you got it wrong, the bad things happen very suddenly and with a loud BANG!Anyway, loud bang, huge blow to face, and finding myself laying on back on floor. All in one instant.The bit of steel had come loose, turned, jammed the cutting blade, and been thrown end first at my nose. Like being punched in the face, but with a pointy thing. I can assure you that it hurt, a lot.Nice cut and swelling and very painful cartilage nose end bits for a while, but no permanent damage.The whole thing was about as stupid as grabbing the wrong end of a soldering iron. I have no idea how I made that dumb error. Normally I wouldn't have. Not going to again.

As for serving coffee that is too hot McDonalds would have been held liable for any and all illness caused by the coffee not being sterile due to not being held at sufficient temperature.

I love my WSD81 ... and the Antex is just a faded memory.

Nevertheless good technique allowed the construction of a vast amount of electronic devices.I'm the happy owner of of a Blackjack BK6000 rework station, currently somewhat underused I'm afraid, which is my instrument of choice on my bench. However don't expect me to throw away my collection of old soldering irons; I for one won't be without them despite the scars!

content: I have not grabbed the wrong end of a soldering iron, but I did get molten solder in my eyeball once.I was desoldering a shielding can on a circuit board and didn't realize the can was in tension when soldered in place and actually quite springy, perhaps it was squeezed into slightly misplaced holes on the PCB or something. As soon as the last bit of solder melted on one side the metal sprang out of the PCB acting like a little catapult throwing the molten solder right into my face. No permanent damage, I did have a yellow spot on the white of my eye for a while, luckily it didn't hit the lens area. I didn't realize it had actually hit my eyeball (I was too distracted by the solder burning my face) until I looked in the mirror later and saw the spot.

Usually, when you change tips, you can put the new tip in place by bare fingers... Ouch!

content: Quote from: klr5205 on February 10, 2014, 05:40:13 pmI actually am wary of ever changing my iron tip when it is not on. Or even interacting with it much when it is off. If I develop a muscle memory for tip changing on a cold iron I could easily accidentally do it when distracted when it is on, but if I learn when the iron is hot and I always have to use the silicone heat resistant pad then no big deal if I am distracted and use the pad even if the iron is off. Sort of like I developed the instinctive habit of always tapping my pocket to see if my keys are there when leaving the house whether or not I am locking the door, make the default case I learn fail-safe and don't have to worry about it in the future.I still have issues where I instinctively untangle the cord of my soldering iron waving the tip around or pulling it towards me without thinking, it's because I regularly have to untangle cords not attached to hot burny things.
