This is my experience as well.

My guess then is its a lack of flux.

:nod:

I've never had an issue with TQ wire, personally. :)

no flux, no flow. flux is a flowing agent, so without it it can be hard to solder. that is why most solder you buy now will have a little in the center of the wire, so you don't have to add flux separately all the time.

This is always a good read when having issues soldering. http://www.rctech.net/forum/radio-el...ef-lesson.html

I've used TQ wire for a while and like it very much. Ralph is great to deal with as well. Fast shipping is always a plus. I ordered one Saturday morning and he had it out before the Post Office closed at noon.

As long as your wire is relatively fresh and not corroded you will be able to get a good joint if you use the proper solder, proper flux and the right amount of heat (not temp - heat).

Clean wire, pre-tin with 60/40 to 70/30 rosin core and a bit of flux, good heat till it flows, make your connection. Done ... Good luck

what ? are you twelve years old ? just kidding but flux has been incorporated into rolled solder for a bazillion years. Seriously people, soldering has been the same for hundreds of years. Rosin core solder? decades at least.

I just checked and I have 60/40 rosin core solder. I have been soldering for a long time, and this TQ wire I cannot get to tin...

I always use flux on a wire/connector that hasn't been soldered on yet. A new surface can be tricky without some extra. Works for me! :nod:

Contact TQ maybe? What iron are you using?

Have you used the new iron on anything else with success? (Could it be a bad unit??) I've heard of old solder going stale, how old is yours?

For what little it helps at this point, I have a bunch of TQ Wire in many colors, never noticed much difference soldering compared to any other, including Deans, Buds, etc.

I heartily agree to always use just a touch of additional flux, especially on new work, just makes it so much quicker and more reliable (less chance of cold solder).

I am using a brand new Trakpower 950. I bought new solder today and could not get it to work. I soldered up another ESC with silver wire and it worked flawlessly.

Contact TQ Wire.

I did. I will report back.
