Re: Wire type questions

Tinning wire is a very toxic process and is only done in India and China nowadays. It is of course the lead content that protects the wire !

Re: Wire type questions

Lead is not used in solder in the USA. It is called tinning as it does use tin, the metal, to plate the wires. I know of at least two manufactures in the USA.

Good answer to OP question. The negative is just as often a problem but is often overlooked, especially if you can't easily trace where it goes.

Re: Wire type questions

"Lead is not used in solder in the USA."
You've been misinformed. I recently bought a roll of Kester solder, a widely known and long established brand. And it says right on the box "LEAD ALLOY" and lists precautions.
Now, if an American manufacturer wants to sell goods in the EU, and California, they may have to use lead-free solder. In California they have even banned lead wheel weights (for balancing car wheels) which has resulted in some national chains going entirely to less effective wheel weights. CA says the lead weights get thrown off and contaminate the ground.
I make it a habit not to inhale while soldering.

Re: Wire type questions

I do believe that plumbing solder is now lead free, it wasn't all that long ago that it also contained lead.
Maybe this was the confusion

There is no controversy. Boat wire is not required to be tinned at least in the US.

Most solder (even electrical) you buy at big box stores like Walmart or even NAPA will usually be lead free. There is a big movement to get rid of the lead from "regular" peoples hands.

However, I still find leaded stuff at specialty stores or online. I usually just order online 60/40 Kaina brand.

Re: Wire type questions

There's no controversy about whether boat wire "should" be tinned wire. Pretty much the same as there was no controversy about whether Catholics or Protestants were to be damned for all eternity not so long ago in England and Ireland.

Some of us are either wastrels and suckers for preferring tinned wire, or perhaps, stacking our odds for long-term electrical reliability.

At some point in life, some of us simply get tired of seeing punked out wire, and are willing to make great effort to see less of it.

Good on you for wording it that way! I think the key in your post is "less of it", and not "none of it". I think there is an untrue perception that tinned wire doesn't corrode. Or that it will eliminate your wire corrosion problems. It does corrode, just corrodes slower.
