No, wirewrap is completely different. It uses insulated (_not_ enameled) 
#30 wire that must be stripped before wrapping. A motorized tool wraps 
around 0.25" square posts. The sharp edges cut into the wire to make a 
gas-tight connection. The connection is not soldered.

Trust me -- Early in my career,I spent hundreds of hours making 
thousands of wirewrapped connections, and I even bought a Gardner-Denver 
AC powered tool for home use (vs. the battery-powered tools we used at 
work). I still have that tool, and a thousand feet of #30 wire, but I do 
little wrapping these days.

The Vector tool is just a plastic "pencil" with a hollow metal tip 
through which the enameled wire feeds. You manually wrap the wire around 
a pin, move the pencil to the next pin, wrap that, and cut the wire. 
Then you solder both pins. The solder melts through the enamel to make a 
normal joint.
