Soldering Iron

[NativePaul]

I took the 8g wires off to replace with 10g to save weight, the 10g had no problems going on.

Rather you than me using a torch on an ESC, I would be too scared of a fatal static discharge.

I had and have no intention of trying to use silver solder on electronics. I wouldn't even try that on a motor, I have never broken a joint and don't need more strength so why risk that much heat?

You race differently over their then we do here, I am not worried about strength in a plug joint.
I am worried about enough heat in the plug to melt the solder.(we do run High AMP setups over here)

After two mishaps as of late;( I have had two solder joints come unsoldered while running, there was even solder balls in the bottom of the hull from the melted solder)
That is why I am moving every thing up to the Kester Silver Solder with it's much higher melting point.

When looking for silver solder be carful out there, I have even found some 96/4 with a low melting point for Silver Solder.

We do race differently here, I race at an average of 45 amps, hence me not wanting to waste power hauling 8g wires around.

We also speak differently, silver solder is 40%+ silver hard solder here, and melts at 2-3 times the temp of either of the 4% silver bearing soft solders linked above.

Yes the term silver solder in the UK is a brazing method that must be done with a torch, different lingo this side of the pond.

I like this stuff. http://www.parts-express.com/4-silve...ProductDetails

Sorry Mike I missed your post,
Nice find, and with a melting point of 422F should be high enough and not impossible to work with.

The stuff that Castle used is Kester - 96.5 Tin, 3 Silver, .5 Copper melting point 430F.

Larry, if I get the solder Mike pointed out will I be ok with my Weller 80watt? I also have a Weller solder station with adjustable temp but not sure of its specs - it's older.

[bob horowitz]

The regular tin-lead solder I use melts at 420F, and I use a 65 watt iron. I don't think you should have any problem with an 80 watt iron. There is so little silver in that solder that it should work just like regular soft solder. Like Paul, I think of silver solder as hard solder. I use it to braze carbide to steel for tool bits. Always use a torch and a boric acid type flux. For hard silver solder, you have to get the parts red hot (glowing red) for the solder to flow.

Where do you find this solder???
The best 60/40 that I can find is 370F most other brands are from 312F to 325F

Ray I have a Weller solder Station also, it adjusts up to 800F, the only problem is that the tip is so small the heat is sucked out of it pretty quickly.

The 80W with the large copper Hammer head should work OK for plugs.
Tin the wire, tin the plug to about half full. Heat the plug up good, hold the heat on the plug- insert wire, let the heat penetrate the wire until you see the tinned wire re-melt, remove heat, do not move until cool.

I get it at my local ACE hardware store. When I get home from work, I'll post the name and details. 420F melt flows great easy as pie to work with. It is not a 60/40 solder.

Well, I made a mistake. It is a 60% lead 40% tin solder. It does have a 420F melt point. I don't have the card it was on but when I get a chance I'll get the info. I'll see if I can pull it up on the ACE web site. Sorry for the confusion.

Guys, turns out I was doubly confused. Checked the ACE web site. I unknowingly bought two different solders. One is 96% tin 4% silver. The part number is 62963. The melt for it is 430F. The other one is 60% tin/ 40% lead. The melt for it is 374F. I've used both with my 65 watt iron with no problems. They both cost about $6.50 for a small tube. Both are rosin cored for electrical work. Sorry for the confusion!

Larry,
How did that giant soldering iron work out with doing the 8mm bullets.

I have not tried it yet with the silver solder, I am waiting for the solder that I ordered.
I did give it a try with the solder that I have here 63/37 and it worked great.
It takes a while to heat up the iron, but once there it heats the plug up in seconds.
