Hey whats the best way to add more solder to a joint?

Is it best to hold the tip in the solder then add more?

What are you soldering exactly? It's easiest to first melt the original solder and then add some more. In order to melt the original solder, you will need to 'wet' the solder tip. Also make sure it's not too hot and DO NOT hold the solder on the joint for too long if it is a heat sensitive device like an IC. They can usually take about 5-10 seconds at I believe 400C (I may be wrong on the temp)

The correct way to do it is to hold the tip of the iron to the part that you want to solder and wait for it to heat up. Then feed the solder into the part not to the tip of the iron. You know you've done it right if the joint is nice and shiny. Some people just feed the solder directly into the tip of the iron and just let the solder lump onto the joint. If you do it this way, you'll get a "cold joint" which is weak and is identifiable by is dull silver color.

How about some tips on soldering wires to circuit boards that have solder on one side around the holes of the board; apply the iron where?

hold to the lead and to the copper on the PCB. Put the solder on, and when you've got enougn(it slopes up the lead), remove the solder and leave the iron on it for an instant, and remove it. tada!
