I have some slp bolt in sfcs installed on my car.
I have a 120volt mig welder and i am debating whether i should tackle this project myself or have a pro do it. This would be my first time welding outside of some practice with scrap metal. What do you think? Do you need a 220 volt welder to do this?


I found these instruction online.

Yes definitely have them welded. That's my opinion. Mine were bolt in, but I had them welded

Unless you have a drive on lift at home I wouldn't recommend trying this for the first time. The reason I say this is because it takes alot of practice to weld while laying on your back the lift just makes things much easier.

Have you ever welded over head before? The bead is the same as the flat welding position, but overhead needs some practice. How thick is the steel on the sfc?

I did mine with 110 volt MIG welder, using four rhino ramps as my drive on lift. However it wasnt my first real welding project and therefore wasnt really a big deal. As far as doing it for one of your first welding projects other than scrap metal, I dont know if its such a good idea. Good welding takes time, patience, and experience. However, if you are confident enough in your abilities then do it. Its a pretty easy job minus fitting the MIG gun in some tight spots and welding overhead. If you do it make sure you wear a hat at the very least, or an actual welding hat if youve got one.

He has acces to a lift (mine) but i already told him i recommend a pro

Pretty much the way I did mine. There wasn't quite enough room under the car to get the nozzle and a welding helmet (while almost laying on my side) to do the welding. Somehow I contorted myself enough to do the job, but, it was painful. I wish I could have gotten the car up another foot. Even though the welds are far from perfect, they are still holding up five years later.

I don't trust my own abilities enough to do this.
At least, practice until you never screw up using
appropriate sheet metal gauge and upside down
position.

I'm not keen on the idea of burning all the zinc
off the inside of the sheet metal, but you might
be able to shoot enough cold galv in there to
slow down the rust.

I don't think too little heat is going to be your
main problem (120 vs 240V machine). You'd be
duty cycle limited, sure. But you should not be
laying long beads anyway. Blowing holes in sheet
metal has always been my trouble.
