floor pans with mig

[esoteric]

hi all i'm new to the whole mig welding thing. I played around with a mig at work but not experienced at all. I recently bought a car and have to redo the floors. My neighbour sold me a mig for pretty cheap but and i'm having trouble setting it. I'll get a pic of the controls some time soon, but what it has are two buttons and a knob for the wire speed. I know one button is like a high/low but don't know what the other is. Any ideas?

I'm going to use flux-cored wire to do the welding. I've cut and cleaned out the floors to receive the new/used ones. I've drilled the spot welds and seperated the pans from the rest. My question is when I weld them in can I simply weld the holes shut to the car? When I put the pans in, do i drill holes to line up to the holes in in the pans and fill them up?

Thanks and sorry for the long post.

Post a photo of the front panel. Two switches side by side generally mean you have 4 power settings - high/low will probably set the range, and the other will likely fine tune within that range.

Have a read through the tutorial. Plug welding is what you want for the floor pans, but working through the rest of it ought to help you get to a standard where plug welds are easy to do. It's handy to have holes in one panel and no holes in the other.
