Quoted from Spudgunman:
Well I can tell you its not galvinized and looks the exact same wire.
I can also tell you that there is no such thing as "pinball wire" they just buy what works
I refuse to pay $1 - .75 a foot for wire that is common hardware store part.
Vid yes it took fine wire solder with flux core (didn't add extra flux and it took)

I'm laughing out loud because I used the same thing for a repair. The stuff works like a champ.
If you don't need a great deal of wire, any lighting show-room in your city should have that wire in stock. They could probably order a spool for you if you need a lot.
