Can you spot weld with a normal Mig?

[TroubledSoul]

I'me still very new to welding. I' ve done a basic course but have very little experience otherwise. I have to replace some bits on one of the cars and they are meant to be spot welded.

Is that the same as essentially tacking something or is there something more to it? Can I use my regular (gas) mig welder?

Cheers all, very helpful. I've since done some more research myself too and see that there's a Sealey spot weld nozzle for my welder. That Eastwood spot weld kit says something about Tweco torches but I'm sure my Sealey Supermig has a euro torch.
