I have read that I should tin the tips of the wires meaning add solder to the wires... before soldering to the point on a board *Joint*.. Is this true? Then I have heard that I should heat the joint or point on the board and apply solder... then touch the wire to it and apply heat from the iron... That doesn't sound to right.. How can I hold all 3 things in my hand at once? Why not just heat the joint and use the soldering iron to hold down the wire and apply solder? Isnt that the better way?
