But this story ends well! Can you see the difference?

Compared to stuff I've seen, that's not even hall of fame material.

For a number one contender, search for DominicD's "Monkey with a soldering iron" post.

Unfortunately, seems like the picture on that post has been affected by the dreaded Photobucket subscription requirement....

You can still see the picture if you cut-and-paste the URL to a new browser window. Just does not work when embedded.

Yup that is hall of fame material. On the other hand, it's clearly low current connection as the wire is so thin. It may actually have worked ok.

Whereas in the connector I just replaced, there were signs or arcing. High current and no contact does not go well together

That is obviously a problem of not having a large enough iron for the job. The wire wicks up all the heat and you get cold solder joints. Maybe there needs to be a soldering forum? So folks can show what is a good vs bad solder joint. I can solder probably far better then most folks. I have done wire mods underneath BGA's and all sort of other custom solder jobs in my past.

But if you asked me to weld my welding looks just like the solder jobs posted. And I don't know what to do to fix it. Which is probably where a lot of folks could use some helpful tips on how to solder better. They probably know it's wrong but don't know how to fix it.

Soldering is about getting the heat right to get good flow, and steady project...

Welding is much more complex. even with good kit, I don't think you can get good at it by reading the way. To become a good welder you need a good teacher, and lots of experience... neither of which I have

Same here.
(except I use head goggles instead of a microscope, and maybe 45 years)

Good soldering is easier and takes less time than poor soldering.

Soldering can be complex to depending on what you are soldering. For what we do with heli's its mostly wires and connectors which is simple. But still if you have never done it it can seem complex. Having someone that knows what they are doing and can point out what is wrong is a huge help.

I know the concepts of welding. But I don't know if my problem is my cheap HF welder, the wire speed, the wire I am using, the gas I am using.....ect. I don't really weld much so I dont care to much. But I know I would weld way better if someone was able to point out what I was doing wrong. Which I am guessing is the same problem a lot of folks have with soldering. They have a problem and they don't know how to fix the problem or even how to describe the problem.

I am kind of surprised we dont have a soldering section for folks to ask questions. We laugh at all the bad soldering jobs but these things could be dangerous and frustrating for folks that want to get it right.

As a welder I like flux core over hard wire.

We have a saying you're either a good welder or a good grinder lol love welding tig, mig or stick love it all. orbital is also very fun to do. Even though you just stand and watch in amazement the weld is beautiful. We got a large job running chocolate lines at Nestlé. All sanitary and tons of free ice cream, Best job ever! You've never had ice cream till you've had it fresh off the line

Thumbs up Formal Term :

Inner Shield : No Gas, - Common in the field in wind conditions :

Lil - Smokey for most > FLux is INSIDE the wire

Handy - Use it on the BIG Stuff - Like 4 -6" with multiple nozzles in one pool right down to welding uber thin rust on JUNK !!

If your interested : I can ref a university doctorate level Class Text Book -

A Good Multi Cert Welder with Old School Knowledge and Experience with History can literally right his OWN $$$ ticket -
Very Valuable - Lost Trade Craft

Then you never had ice cream either, since it should not come off a "line"

I've been struggling with large connectors on my Hakko FX888D (takes longer to heat the solder joint than it should) so I figured an increase in power was in order.

http://www.jameco.com/z/LF-3200-Xytr...y_2181503.html

I almost got the LF-3500 (150W) but then I found out that it uses a different iron that uses larger tips and as a result smaller tips aren't available for it. Apparently Xytronic USA's website got it wrong when then labeled the LF-3000 / 3200 tips as also fitting the 150W handset because apparently they actually don't.

It uses 44-413XXX series tips i.e. anything made for the HF90 handpiece. However a few of the LF-3500 tips also have 44-413XXX part numbers, these are labeled as for the HF150 handpiece. Howard Electronics has a few of the HF150 tips listed as working with the HF90 when they do not. I think someone probably just copy pasted the page information e.g. this page:

http://www.howardelectronics.com/sol...ering-station/

It says "for LF-3500 iron" then at the bottom it says it fits the HF-90 handpiece when it obviously can't.
