lead fumes aren't nearly as much of a danger as flux fumes

>>2504486
Lead does not vaporize at soldering temperatures. Additionally, the flux used on lead-free solders is more dangerous.
So I always use leaded solder. I hoarded a bunch of it, as prices are steadily rising.

i don't have any problems with rosin core but it's all i ever used since i got into soldering after they stopped allowing people to sell it with lead.
where do you source FULL HYPER LEAD solder from?

>>2504486
I only solder electronics so yeah I use lead solder. Usually I breathe in some, then go "oh shit yeah ventilation" and open a window and point a fan at it.
Also handle lots of lead pellets for my pellet rifle but they don't leave much residue.

>>2504515
> where do you source FULL HYPER LEAD solder from?
got a couple spools on Amazon. I think this brand https://www.amazon.com/Alpha-AM31605-Leaded-Rosin-Solder/dp/B00QS8R7QS/

>>2504486
>do u just rawdog the retardation fumes?
lead has to be heated to 3180°F to produce fumes.

>>2504528
>he doesn't solder with thermite

>>2504528
Well but cant u get lead poisoning by just by touching it?

>>2504486
>do you use solder with lead?
No, because there is zero need.

I use 0.3Ag 0.7Cu and it gives me perfect solder joints. If you can't solder lead free then you've got the mental capacity of a gorilla. Just add more flux faggot.

>>2504549
>Just add more flux
And with flux I specifically mean **ROSIN**, not some low tier synthetic garbage that they call "flux" nowadays. All you need is ROSIN (colophony), it's literally just resin that leaks from coniferous trees. It's literally fucking free if you just go into a conifer forest and collect it. You can also dissolve it in isopropyl alcohol to make liquid rosin, or dissolve it in less alcohol to make a sort of paste and it works really well. Don't fall for the synthetic flux jew, return to tradition.

I bought a 1kg bag of purified rosin that will last me probably a lifetime of soldering.

>>2504541
No.

>>2504555
Looks tasty. Does it smell like a forest campfire while soldering?

>>2504555
So you mix the purified with alcohol and thats it?

>>2504486
I don’t think the fumes are so much from the lead as the flux. You get the same shitty fumes from lead free solder.

And yea, I used leaded because /diy/ shilled me on it. Surprisingly hard to find but a NAPA had some good 60/40. I think finally a few more places are expanding their electronics repair selections, like Home Depot finally got some good soldering accessories about a year ago and Harbor Freight brought new stuff in as well.

>>2504608
>Looks tasty. Does it smell like a forest campfire while soldering?
Yes, but not as nice as fresh rosin from conifer trees. I did solder with fresh rosin from my backyard and it's really nice. I think the heat treatment which is required for filtering / purifying makes it lose a lot of aroma.
>>2504613
Yes, that's it. I use 99,99% isopropyl alcohol, it takes a few days for it to dissolve. You could use ethanol instead of isopropyl alcohol, but I used what I already had.

I filled one of these 100ml plastic bottles with a dropper tip that you can squeeze to dispense the viscous rosin/alcohol mixture.

>>2504549
Liquidus and solidus points are different with lead-free solder. You need a higher temperature soldering iron. Silver products like Worthington or Johnson Mfg are the good ones. For soldering with a propane torch, better use 60/40.

>>2504486
If you gave me a case of lead free solder, I would toss it in the trash. I wouldn't even try to sell, it because that would mean someone else using that trash.

>>2504541
No, you have to eat it. Like you eat pennies.

for electronics work I use lead
usually kester 63/37

>>2504486
Lead based for everything that can potentially move, such as USB plugs, audio jacks and switches. Lead free for all fixed components.

the only lead free solder I've ever tried was garbage that wouldn't flow and wouldn't stick. You can probably get decent stuff if you want to pay for it, but I like my cheap and effective leaded solder where as long as it isn't the shittiest possible junk from aliexpress it works fine. The lead isn't really the risk when soldering anyway, it never gets anywhere near hot enough to vaporize, all the fumes are from the flux and other shit which is present in lead free too. As long as you aren't chewing on it or getting your fingers coated in lead dust and licking them then occasional hobbyist level soldering isn't really a significant risk of lead exposure. Just having decent ventilation and trying to keep your face out of the smoke is plenty of safety.
If I was doing it hours every day professionally I'd have enough of the proper safety equipment that it doesn't matter what nasty shit is in it though, lead free or not.

No, because leaded solder is outlawed in the EU.
I believe the solder I use has flux core, however.
Can't even buy leaded solder here.

>>2504827
what are estate sales?

>>2504541
only if you touch it and then don't wash your hands. Or have kids that might pick up shiny bit of lead drop on floor.

>>2504844
where you go to buy old bottles of mercury

>>2504496
how worried should I be about flux fumes. I basically huf that shit when I'm working in close.

>>2504486
soldered for years with lead solder never had a problem
soldered for years with led free never had a problem
if you struggle with lead free its because you are bad at soldering, don't understand the process properly, aren't doing it right.
get good.

>>2504913
flux fumes are nasty but the quantities are generally small.
if you inhale them regularly it will cause some medical issues.
but any fan is
enough, also wash your hands after soldering

>>2504844
It’s like an auction at somebody’s house after they die when the kids want to get rid of all the bullshit and get some cash.

>>2504486
Leaded solder is superior in every way, but companies love planned obsolescence far too much to not use garbage solder that cracks in 4 years.

>>2505568
it was probably electronic companies that paid for the legislation that removed lead from solder to begin with.
just so they could pretend they were for the environment while producing electronics that break faster.

>>2505634
I could see that.
But i also see that there are (though only minor) health risks with lead

>>2504486
LEAD4LIFE 63/37, eutectic gang.
for the fumes thou, I don't really mind it however my brother fucking hates the smell so I use a tabletop fume extractor.
and as long as u don't eat lead dust or blobs u wouldn't get retarded ;)

>>2505705
lead isn't too bad in like one VCR or cheap Chinese electronics, but imagine a landfill full of them with nasty acids that can leach the lead from the PCBs into water-soluble compounds which gets into the water supply...
scary stuff if u ask me, I would rather lose the lead rather than poisoning the water supply...

>>2505710
but lead free solder joints will probably not last as long as lead solder joints.
thin whiskers etc. so maybe we end up with more waste because electronics fail more often.

>>2504486
i used to use lead based solder. then i switched to lead free. the only reason was cost. the lead free stuff was cheaper and seems to do the job

i am not a expert or even good at making circuits but i have made working circuits and mostly the trial and error required more solder be used. so the cheaper solution was more desirable. this is based on the pricing at the time on amazon which may not hold true now

it should be stated i also used plumbing solder which has silver in it (yes regardless of what any one says plumbing solder has silver in it but its only like 3%) and found no problems it just doesnt have rosen so you have to use your own flux. i dont use it now because its more costly

>>2504549
>No, because there is zero need. If you can't solder lead free then you've got the mental capacity of a gorilla. Just add more flux faggot.
Leaded solder produces better quality joints. It also needs less to melt heat so it works better with low wattage soldering stations and produces less fumes.

If you need to comply to RoHS standards (=you manufacture consumer electronics), can't source leaded solder or you are just used to lead-free, ok, use it then but technically speaking leaded is better.

>>2504515
Look at smaller stores who mainly sell to small business and hobbyists.

>>2504549
Stupid question but is this by mass or by volume?

>>2505560
Wait he's gay? I only knew he liked to vape

>>2504827
>Can't even buy leaded solder here
Here in Romania I bought leaded solder lots of times from a local electronics shop. Do they mean it's illegal to sell it to a business?

>>2505923
>Stupid question but is this by mass or by volume?
I believe it's by weight as metal alloys generally seem to be given by weight, but I may be wrong.
The one I use is: Sn97 Rosin2 Ag0.3 Cu0.7

There are lead free solders with even higher silver content, but I've not tried those.

>>2505923
It's by percentage, 0.3=30% of the solder (by weight) is Ag (silver) and 0.7=70% of the solder is Cu (copper)(by weight). A very common solder is 60/40 SnPb (tin and lead). There is also the flux core but that is such a small percentage of the solder that it's not even mentioned.

>>2505979
Sorry now I realised you were asking if the percentage was by weight or volume, I'm a tard on Saturday evenings/

>>2505781
from my experience its the components that fail first not the solder joints (unless poorly designed), whiskers also accrue in leaded solder just not as fast from what can understand...
ppls rush towards cheap crap and the drive for lower quality better bang per buck products that are not designed to be repaired/serviced compel us to throw more trash away, think of it as the soviets thought of the T-34-85/75 were it was clearly cutting corners and rough around the edges but if well maintained can last pretty much for ever, like the T-34-100s used by the Houthi's in Yemen or T-34-85s used in the Yugoslav wars in the 90's, u and i don't mind that cassette players had rubber belts that perish within 5 or so years because in the back of our minds we had the convenience of being able to fix it, we form a connection with our stuff that is hard to cut, unlike now with things being so fragile u feel burdened by carrying what u own in fear of breaking it...

>>2505979
>There is also the flux core but that is such a small percentage of the solder that it's not even mentioned.
All the soldering tins used for soldering electronics have a flux resin core. It's what makes the fumes while soldering and when it's all burnt the solder becomes sticky. You can see the flux core if you cut the soldering tin with sharp scissors and the manufacturer brochures gives you more info, for example is it corrosive and needs to be washed off after solder work.

>>2505996
>ppls rush towards cheap crap and the drive for lower quality better bang per buck products that are not designed to be repaired/serviced compel us to throw more trash away
Worst I have seen are laptops. 10 years ago keyboards were fixed with screws. Now days they use pressed plastic taps. Good luck trying to change it...

anyone use solder paste regularly?
it seems like it's easier to apply (especially in tighter spaces) and the ones i've found tend to have more silver content in them for some reason.

>>2504486
Of course since lead works better but I made a portable fume extractor to keep smoke from any solder out of my face. See videos for ideas but I just connected half a large plastic antifreeze jug to a small shop vac (I collect used vacs for such things). I also use the old trick of panty hose over the shop vac filter which is easier to clean and the filters last many years.

>>2504913
Before I started using fume extraction flux smoke would give me some vile strong headaches.

If you haven't noticed any side effects maybe you're immune or something but I really wouldn't ever solder close without an active air stream. Also if you don't wear safety glasses its only a matter of time before you find a small pocket of moisture and get solder splashed into your eye. Ive been hit in the face so many times with molten lead spatter its not even funny.

I use both. And I never changed my 888d from the default of 750 degrees.

>>2504486
The thing that causes the fumes is the flux, not the lead. I use lead free, but put on a fabric mask I have because I don't want to become unwittingly high/retarded

>>2504488
Metallic lead has very low bioavailability and usually doesn’t stick around in the body because it’s not water soluble and it just passes through. The “toxic” form of lead is when it becomes ionized as a salt (Pb2+) as in leaded paints or following the use of bore solvent when cleaning guns. These ions are water soluble and readily absorbed into the body where they cause neurotoxic effects. Our bodies confuse the lead for calcium and don’t actively excrete the ions too. Our cells even incorporate lead into bone instead of calcium which can temporarily sequester it. However later in life (especially in women) if someone develops osteoporosis this lead can be released back into the bloodstream where it poisons the brain. This is one theory behind early onset dementia. >>2504486

I solder entirely lead free. I also don't use flux if I can avoid it. It's how I learnt it as a teen, and I gotta say, it's awesome to know that as soon as I'm done I won't have to worry about any contamination whatsoever.

I can just grab my soldering iron, put it on my dinner table, quickly fix something, and put it away again. I can be done in a few minutes without having to worry about getting dementia just because I forgot to wipe the table once.

Sure, lead solder is probably easier to work with, but I've never worked with anything else, and this is fine.

Physical lead does not have good bioavailability. It is very hard for it to leech into anything. The issue is when you get into formulations like Tetraethyllead, the component of leaded gasoline. That will very easily leech into you and anything else. The war on lead is one of the dumbest things imaginable. People treat it like plutonium now.

>>2508032
uhuh. Learning things from 4chan for once

>>2508032
>Metallic lead has very low bioavailability and usually doesn’t stick around in the body because it’s not water soluble and it just passes through
This would be correct if metallic lead just suddenly ended up in your bloodstream.
If you ingest lead it ends up in your stomach and the acid will oxidize it to PbCl2. This compound is not usually water soluble but in a solution of HCl it will dissolve and the bioavailability will increase.

>>2508705
>If you ingest lead
And this is not a problem if you don't fucking eat the solder

>>2504486
Naturally. That shit doesn't vaporize at 700F. Also, rosin fumes are not even that dangerous. Just hold your breath when you smell the sweet. Using lead free solder is just a miserable experience. And the lead is way less dangerous than the flux that has to be used with lead free poopoo. Sometimes the old ways really are the best ways.

>>2504827
I can literally buy 93% lead solder no bother
https://ie.rs-online.com/web/p/solder/0556503

It's illegal to manufacture consumer electronics with lead solder but there's a bunch of cunts who get special treatment.
We make boards for aerospace and government owned buses with lead solder

>>2508547
>The issue is when you get into formulations like Tetraethyllead, the component of leaded gasoline. That will very easily leech into you and anything else.
The lead that comes out of an exhaust pipe is elemental and is still bad for you. The ethyl groups get removed during combustion.
>People treat it like plutonium now
If plutonium were easily available, people like you would talk about it the same way you talk about lead now.

>>2504549
>>2505979
you solder at 800C?

>>2504486
Without.
I hate non-leaded solder but definitely without because the lead is not worth it.
Once it's in your body you can't get it out of you.
But as for the decline in IQ issue? That's only a problem if you're less than 25. It impedes development moreso than existing conditions.

>>2504496
I also am skeptical about the healthiness of tin too.
We ignore it because it's everywhere, like aluminium (which is ALSO problematic we're beginning to find - looks like glass and ceramics win again for the container competition).
The problem is, we haven't had this scale of these metals in the past until the industrial revolution. So only now are we discovering these major concerns.

First it was arsenic wallpaper. Then it was coal, lead and fibre cement/asbestos.
Now we're finding issues with almost all of our plastics, aluminium and metal containers.

I think the problem is differentiating between "necessary concerns" and "not that harmful" because frankly even water is not healthy in doses. It's all a game of input/output and finding acceptable levels of chemicals in our body. Establishing a healthy sustainable internal environment. Perfect that and you basically master immortality (that's how impossible it is).
Frankly we're in the intermediate stage between complete barbarism in the pre-WWII times to the next potential stage (though we have administrative issues with weeding out problems nowadays, especially with chemical product manufacturers) where we actually have constructive oversight and education on such things.

But unfortunately, we never left the industrial revolution and it's toxic malevolence. It's always around us and we ignore it daily. It's not just a difference in detailed observation, it's definitely a difference in the chemical status quo of our modern environment.

>>2508036
>Lowkey this system is fucked up, why change my phone every 2 years
I understand the push for changing degraded/corroded parts for health safety reasons, but then they make it nearly impossible to do that without their paywalls and specialized techniques - which kinda renders their arguments for "health and safety" total bullshit.
This shit should be made easy to do for health and safety reasons.

When did this board become filled with such beta pussies? Soldering with lead is perfectly safe unless you're an absolute drooling retard and even then you'd have to try pretty fuckin hard to get sick.

50/50 solder for boilers and other non-drinking water joints, 95/5 for drinking water pipes (use Mapp gas for better flow).
Or, even better, get a press tool and never have to solder again.


>>2504541
No you fucking manchild. You get lead poisoning from ingesting lead or breathing in lead fumes. So, don't eat any and keep your torches under 3000 degrees.

I like how half the thread is about electronics soldering and the other half is about plumbing soldering.

>>2510594
>Just buy a jar of flux like normal people do hippie.
Normal flux is rosin dissolved in vaseline/glycerine/dunno with some activators.
Rosin is cheaper and better for wires or THT. Flux is better when dealing with microscope shit as it doesn't get dark as fast because of 11 herbs and spices they add.

>>2510669
>>2510594
Oh right, plumbing flux is zinc chloride, and it is cheap so no need to invent stuff. It is more aggressive, too aggressive for electronics.
