How do I choose which tip to use on the TCP Weller soldering iron

On the Weller TCP soldering iron the tip determines the temperature of the iron.

Im fairly new to soldering so Im not to sure which tip to use.

I will be using the iron to solder resistors,capacitors, leds and IC's to veroboard/stripboard.

Which shape of tip should I be using and what is the temperature the tip should be at?

I found this information on the net for the TCP weller iron.

"The Letter is specific to the tip's profile/size (mass).
An "A" tip is 1/16" screwdriver profile
The Number determines the controlled temperature

6 - 600 degrees F
7 - 700 degrees F
8 - 800 degrees F"

So which tip should I be using?

Any help would be greatly appreciated. Thanks.

I have tried all tip temperatures about 47 years ago and selected 700 degrees F as the best one for old leaded rosin-core solder. Because the tip is plated and because the iron has temperature control then the tip lasts almost forever. I clean it on a damp sponge.

Each solder joint takes about 1 second. I also use it with a plunger (slurp) desoldering tool.
