what kind of solder for welding turnigy silicone wire

[lifepo4ever]

today i just try to weld 10 gauge turnigy silicone wire and the 60/40 solder won't stick so what kind of solder i need ? thank you

 

[lifepo4ever]

ok its silver plated but what is the best solder for high temperature?

If your solder won't stick, you probably need some flux to help it flow.

also a powerful enough iron ... 10g can suck a fair amount of heat up

im not quite sure but maybe i need silver solder or better also it as to be very resistant to high temperature because i want to solder phase motor wire inside

i use a butane torch and it doesnt work!!

If it's the same silicone wire they used on the Turnigy Watt meter, then yes, it will solder just fine with 60/40 flux core, even the multiple-decade-old stuff I have here. For connections too large for my 50w-ish iron, I use my "pocket" butane torch on it's lowest setting, keeping the flame itself well away from the wire to prevent overheating/oxidation/etc.

Rosin core lead/tin 60/40 should be the ideal solder for that wire.

Lead/tin solder sticks to silver and copper both extremely well. It should be some of the most simple heavy-gauge wire soldering you've ever done.

If you're not able to solder to it, and you're actually getting the temperature right, then it's not silver-plated copper wire you're dealing with, but rather aluminum wire. In this case, unless you're a pro and have zinc solders and the right flux, I would just swap to a different wire.

well i had to try with my electric iron 45w and its work W.T.F , the butane torch is supposed to be a 1000 degree lol

Hotter is not always better when soldering. You're probably heating the wire so much with the butane torch that it is oxidizing the metal, and the solder flux evaporates or chars before it can deoxidize it, so then nothing will stick to it properly.
