Default *urgent* do i need feeding wire?

For spot welding, so i need feeding wire?
i rent a welder last night, about to get things setup and weld my radiator support now...

i was reading spot welding stuff online and found this
http://www.esabna.com/EUWeb/MI...1.htm

do i <u>absolutely</u> need the "spot welding cup" for spot welding?
and again, do i need feeding wire? (i thought feeding wire is needed say to weld 2 separate piece or if it has groove.)

the welder i rent is Lincoln Weld-Pak 100HD, i read the description and i should set it to C-1.5 to weld ~1.6mm metal. (JDM rad support is like 0.5mm, the frame is about 1mm)

any input would be much appreciated!

If you had renteda spot welder, no.
You rented a MIG, so yes.
If you use Fluxcore wire, you'll need no gas tank or lines. If you use MIG wire, you'll need a tank, regulator (possibly), and Argon or Trimix, or in a pinch, CO2.
