Soldering 1/4" Jacks - slippery?

What's the trick here? I've ALWAYS had this problem when soldering quarter inch jacks - the solder dries and just slips right off!
 
Flux isn't really necessary if you are using rosin-core solder I believe.

Do you have issues soldering other components? Are your solder joints shiny or are they grey and dull? If dull, then you probably have cold joints.

Are you soldering to the flat, spade-type connectors or the eyelets? The spades can be a bitch, but I use one of those "helping hand" things to hold them in place for me.

The sanding method can work too if all of the above doesn't.

Also, make sure you tin (apply a bit of solder to the tip of the iron) before soldering. It makes a gigantic difference by transferring heat quicker.

Yeah, you tin the tip of the soldering iron, then you tin the surface of the lug. You can even tin the wire, but it's not necessary most times, as the solder will wick up into hot copper.

You still have to get the plug really hot. For tinning or for soldering. Otherwise you get a cold joint. If the solder looks like mercury... like a bubble... like Terminator 2000, then the lug isn't hot enough. It should spread like melted cheese/wax/butter/yum.

Hold the iron to the spot you're going to attach the wire to. With your other hand, hold solder to the plug, without coming into contact with the iron. When it melts on its own, you know it's hot enough.

Hint: Use an old pedal. Insert plug into jack. Much less finger or other object burnination.

Side Note: Sometimes you can smell burning meat before you even feel that you've burnt yourself.

Oh yeah: Don't solder while wearing shorts. The molten solder can jump or drip at times. That shit is good times.
