I recently bought a soldering iron for rc heli use. I have watched many videos on youtube about proper soldering.So I heat up my iron and try to gently wisk a little solder onto the tip to tin my tip but the solder just drops to the ground in the form of a ball bearing and wont seem to stick to the tip. The same thing happened when I tried to solder 2 wires together.Is my iron not getting hot enough to turn the solder to the melting point or am I doing something else wrong?

Is the solder you are using rosin core fluxed solder or are you using seperate rosin flux with the solder.

What solder are you using?

What is the condition of the soldering iron tip?

Is it black and oxidzed?

soldering problems
The solder came with the solder iron so I dont know what it is but the tip is shiny, its a brand new iron.Maybe I should go to my LHS and buy some new solder, that was my first thought.

If your soldering small wires use small gauge solder( rosin core for electrical use).Wait until the iron is fully hot,then tin the tip and wire.

I'd rather be flying!

If the soldering iron tip is tinned (shiny). The proper solder should just flow right on to the iron. When too much solder gets on the tip it will just drip off and form those little balls when it hits the table.

If the iron gets the wire up to temp the solder should just wick right into the wire.

Sounds like the solder has no flux in it.

You may find this helpful. I realize you may not be doing PCB work, but the principles are the same.
