desoldering iron

I am thinking of purchasing a desoldering iron, because braid gets annoying, and i was looking at one at radioshack, its just a soldering iron with a hole in its end and the hole leads of a mounted bulb. i was wondering how they work, the iron heat the solder, and u press the bulb and it sucks the solder, but where does the solder go? into the bulb? how do you get the solder out?

Soldering Irons?

My last soldering iron needs to be retired, it will no longer melt solder, and was originally purchased sometime in the 80's. So I need a new soldering iron, but I do not know which one to buy. Should I get a 25 watt or 30 watt to make sure I have enough heat? Also are any of the soldering stations with the variable heat gun worth it? For now I will have to be careful and use my butane soldering iron (I have not burned any components yet).

Stupid Question: (soldering iron) = (woodburning iron)

I have a woodburner and I was wondering if I could use it as a soldering iron? Is it just getting hot enough to melt the solder that I have to worry about or is there some kind of load problem with using a woodburner for this purpose? need help!! (obviously)

Mars as an Iron source?

Could we send something to mars to strip mine the surface and gather all of the iron oxide, then using a solar mirror array direct sunlight onto the days collections and melt them into iron.  Then ship it to earth in a giant iron blob which would be transported by some kind of ship. I assume this either hasn't been proposed or is not practical because I haven't seen anything like it before.

Soldering iron smoking? Answered

Hi Guys, I just bought a new soldering iron for the first time. When i plugged it into the wall outlet it started smoking (not alot) well that scared the living crap out of me, so I turned it off. So can any of you guys tell me that should I just dump the iron or is it normal. Please guys help (and there was a bit of smoke near the handle too). Oh and another interesting thing is that after 10 seconds of plugging it in it started melting solder ( its a 35 or 30 watt iron ) Thanks in advance. -Prickly Potato

Adjustable solder iron

Hello sorry if this is the wrong place, i'm pretty new here. recently i got a 30w solder iron and found this instructable to make it adjustable I know it won't be as good as buying a real adjustable iron but this is cheaper and will work.  I have a little potentiometer that i got from a lamp but unlike most it only has 2 terminals and a space for a third. i did some experimenting and it seems to work fine, the 2 terminals are a middle and one to the right then a space to the left i hooked a wire in the space and it basically worked in reverse to when it clicked off it turned the (in this case) motor. so my real question is how do i wire this up, can i just wire the "hot" wire threw the pot and will it work to make my iron semi adjustable the only info i have on the pot is that on the top it says B500k i can take a picture of it if needed.

welding cast iron to mild steel

Welding cast iron to mild steel is for the most part done with ornamental iron such as gates and fences. the ornaments are typicaly cast iron such as spearpoints and fit over the top of what ever square tubing size ect you are working with. If you weld say with a mig welder in the normal mannor you rweld will cold roll and ball on you leaving a poor appearance that you will have to spend time grinding to make look good. Fortunatly it is not a matter of strenght or how much penetration ect. It is just ornamentation but must look good. Now take your mig welder with say 035 wire and use pure argon..(less spatter). Turn your welders heat up somewhat past what your normanl setting would be for what ever thickness you are using. Use breif spot welding like techniques overlapping as needed. You will find that this makes a good wash bead with no undercut or cold roll. The argon gas helps to keep down all the extra spatter welding cast iron to mild steel seems to cause. Larger peices such as caps for say 4by4 gate posts or fence posts, i preheat as uniformely as possibly to just under cherry red then weld as described. It welds badly because cast iron is actualy dirty, literaly with particles of dirt in the cheap castings, wich the ornaments are. Not haviong the need to be anealed or nodular for instance. If the welds are not going to show then you dont have to do this. It will still weld, just do not expect the clean perfect welds you are used to.  And NO I do not have PICS AND I dont own a digital camera nor do i know how to use one let alone put them on a computer.

bare bronze welding cast iron

If you happen to have a some what rare car, or one that is simply thirty or more years old, you may find that if you ever crack your manifold exauhst that you can not get another by simply going to a (pick and pull) So, the first thought is..most of the time, "I will simply zap it with NIRod". WRONG! an old manifold that has repeatedly heated and cooled is very brittle and the sudden change in temp and too rapid cooling may crack it even more. Now what i do is use bare bronze rod and braze the crack. Here is how i do it. First I find the ends of the cracks and drill a 1/4 hole half way through the material at each end of the cracks. Next I use a rose bud torch and heat up the cast iron as evenly as possible peening with a hammer lightly to releive stress in the casting. After about five minutes of this I quickly switch to a oxy-actl. brazing tip and start my pass. The first thing i do is heat up as much of the crack as i can to cherry red and sear one coat of bronze using plenty of flux. Then I start at one end of the crack and fill in the crack that i had previously veed out with a grinder to half way of the depth of the material and no more than 1/4 inch wide. I use an overlapping spot weld like technique. i lay a small amount of bronze, remove heat for a second and overlapp where i left out. When done I have a bronze brazing weld with no undercut or cold roll. Then i use the rose bud again for some post heating gradulay reducing the heat and peening with hammer again. Then I quickly take the whole peice and cover it in powdered lime so that it cools very slowly. This will stop it from cracking due to rapid cooling. Also it may put some ductility in the cast iron. It takes about four hours to be cool enough to touch with the bare hand. Then I grind the bronze weld flush and inspect the weld to see if i got proper bonding, all you should see is a ribbon of nbronze that has no porosity or cavities. I have also done rare boat manifolds like this when repeative NIRod was used at other shops and they broke every time. Still no 100 percent with cast iron like this. Sometimes it just cracks more, after all it is a dirty porous metal that is very brittel. Anyway, i have had very good luck doing it this way

What advantages/disadvantages do gas soldering irons have over conventional (i.e. electric) models?

I was thinking about getting one of those SolderPro irons, they're cheap, have lots of funky tips and seem to be dual use - i.e. i could use it as a hot air blower and a portable soldering iron.  The '70 looks nice, especially with 100 minutes of use on a full tank. I've got a cheap temperature controlled (i assume, it's got a dial so you can vary the temp, but stupidly no actual numbers so i can have yellow or dark red heat =P) station at the moment which works but takes an age to heat up.  We've got Weller units in the physics labs at uni and they heat up within 30 seconds which is amazing by comparison. Would it be worth getting a gas iron?  I was considering getting one to try some surface mount soldering, but will the temperature control - or lack of it - be an issue?  And finally, what tip would you recommend getting for SM work?  It comes with a conical tip, hot air, knife and a flame tip.  I was going to get a 3mm chisel if i ended up buying one. Oh and this will be for PCB/stripboard/general electronics soldering rather than jewellery or anything else.;=90   Good variety of tips too:;=Tips Cheers guys, Josh

Tinned my soldering iron, now it wont work?

Hi there. I recently read an instructable on here on how to solder (rather, read through several) and all of them mentioned that it was imperative to tin the tip of your soldering iron. So I took out my trusty butane soldering iron, and tinned it with a layer of solder so thin, I can't see a thickness to it, and can only tell it's there because it's shinier than the tip of the soldering iron. My problem, is now the tip doesn't appear to get hot enough to melt solder (?!), as no matter how long I hold it directly on a piece of solder, it never actually seems to melt. I tried brushing the tip with some sandpaper (while cold) and a diamond drill bit (gently! while hot) to try and remove some of the solder from it, but to no avail. I can no longer solder anything. Any suggestions on what I'm doing wrong or how I could fix this? Thanks, Adam
