Hello Guys
Someone lifted the car from the pinch weld back in the day so he twisted where the fender couples to the frame and it rusted.
How could I repair it?
">

 

Wire brush.

Rust neutralizer.

Paint.

Large ball-peen hammer for whoever smashed the pinch-weld.

 

Theres a hole in the pinch as you can see!!
How about cutting and replacing the metal?
Will it be hard to do?

 

I just did this on my trans am, I had the exact same hole. heres my thread

Post #'s 33 and 41 show the kind of cutting I had to do. what you cant see is that I straightened the pinch with vice grips, wire wheeled the rust, rust neutralized, and painted it over. then obviously I welded in new metal and seam sealed and painted

 

Thank you a lot, there is the exact pic i was looking for!
What welder should i use in order to weld it good? (I wanna go cheap)

 

Two basic problems with cheap welders:

1. Poor penetration of the weld.
2. Likelihood that the rod/wire will "stick" when the arc is struck badly.

Quality welders are expensive for a reason.

Cheap welders are reviled for the same reason.

At a minimum you need a 30 amp outlet to plug a cheap welder into.

 

This is a great cheap but decent welder that can do most anything on 110V and less than 1/8" reliably. You will need to get some gas though and an auto dark helmet from china freight.

Go with a gmaw mig welder. for body work like this, using shielding gas is way better than flux core wire.

Everyone says stay away from harbor freight welders but at least there's a store near you that you can return/exchange if a problem arises, it's a different story with all the other cheap Chinese welders on the internet. Obviously if you can get a used miller or Lincoln electric for a good price that is the way to go.

 

The lincoln I posted is only $320 on amazon and is a mig welder. althoug for some reason this site keeps changing it to a walmart link

I live in Italy and here houses got 220v
So Shall I go for a MIG 20/30 amp welder?

 

Check the manufacturer's specs on the welder you are considering.

Be sure your outlet is rated for the manufacturer's power-requirement spec.

 

I am fixing that exact spot now. It isn't hard, it is just a pain because the floor is there.

Also, you don't need much of a welder since you're only doing sheet metal. You'll likely blow through it if you don't practice first.
