Your MiG is probably not set up correctly, either feeding too fast or with too high a current. Ideally you need to seek a bit of help from someone who knows what they're doing, and I'm sure there's someone on here near you that can help.
However, one thing is VERY important, and that is cleanliness. You should run an angle grinder or belt sander over whatever you want to weld in order to create a good contact surface for the machine to arc against. It's the same with soldering. Any impurities and it doesn't work.
There are plenty of videos on Youtube that can help, but it all boils down to:
I hear, I listen
I see, I understand
I do, I learn.
Just one thing... Normally a MiG welder relies on an inert gas to shield the arc from oxidation. (The MiG means Metal, inert Gas) If you are using the machine "gasless" you have to use a special fluxed feed wire that creates the inert gas for you. Ordinary MiG wire doesn't work!
