Title: soldering iron question
Post by: danwelsh on December 25, 2013, 08:46:30 PM
Hi guys....my girl got me a variable wattage iron for Xmas. What wattage would I use for component soldering?

Does the adjustment show wattage or temperature?  Or does it just have a relative scale?

Do you have any way of determining the tip temperature? Maybe an IR thermometer?

I'm pretty certain it's too high for people who know what they're doing, but 40W works for me.

It just allows me to change the wattage

25W is good for most soldering on a PCB. You should go up to 40 if you're doing any soldering to a pot, as in rewiring a guitar harness.

Yep, Jacob hit the nail on the head.  25w for PCB work is more than enough.  Once in a while you might hit a nasty ground plane, but you can just increase it then.

Right on......thanks guys for the help

So I'm gonna take it at 645° (per my iron) for 63/37 solder is "too hot" then? I've never had any problems, usually allows for quick in and out except for pots. Seems to work fine with PCB and Vero (not so quick out there, but that's ok)

Edit: Found the answer to my question:

Not a problem at all.  I use 63/37 at 720 degrees F.  Just get in and out fast and you'll be fine.

Thanks Pickdropper - Think you even said the same thing in other thread.

It's like deja-vu, all over again.

Now, as a physics teacher I feel the urge to insist that you should mention the proper units (or any unit in this case) of your measurement. As a European, your post scared the hell out of me: I only solder at 320, about half the numerical value, degrees...Centigrade that is!

Thanks for adding in the Fahrenheit, Pickdropper ;)

Yeah, there is a rather pronounced difference between 720 F and  C.

Not sure why the US uses F either, but there we are.

645°C ~ 1200°F I bet that's hot, and yeah that'd scare me too. Sorry for the heart attack Rockhorst!

The US uses Fahrenheit because it is superior. Otherwise all of the measurements sound too small.

I live in USA and I wish we used the metric system.  "F" SAE!  :)

Feel the same way but that would require new learn'n, I still get hung up on the pint vs quart !  whats so wrong with say'n 4 cups ? LOL
Had a box come through work the other day from china, had a fraction saying 2/10ths  on it. we laughed like hell half the day
kind of like saying 50/100ths when you could just say 1/2

A pint is a unit of measure for adult beverages.
Cups are used in baking.
All I ever worry about. Everything else I have measuring devices and scales to figure out.

I always suspected that America uses units no one else does just to be ornery. Just like how one of their sports has a "World Series" that only America and maybe a couple other countries participate in (as opposed to the World Cup, which has how many countries?)
