Welding car panels

[payty]

Hi,

I am pretty new to MIG welding.

I am doing some restoration to my car and now I am in the process of repairing some holes in the rocker panels.

I have prepared a piece of sheet metal that will be welded in place but I have some trouble with it: in some places I have to weld from below the car pointing up and the molten wire tends to fall down.

Do I need to adjust the wire speed or the amps? Or there is another solution for that?


Could someone give me some advice?

Also, I have some trouble with the wire feeder because if the hose from the welding torch is not straight, the wire tends to go slower in an uncontrollable manner. The rollers are clean, no dirt or lubricant on them.

I have tried several settings for the speed control button and the screw that is used to adjust the pressure of the roller on the wire but it is not working. Should I change some parts to make it work better?

The welder is a Telmig 170. They say it is italian made, but I did not find many reviews on the internet about them.

You need to urgently fit a new liner mate. Then get your wire speed/amps balanced. If welding upside down you will always get some splatter but if the whole bead is falling off you may have unclean (rusty) metal that you are welding to.

Some mig torches are just like that even when new,fact of life,try and keep it straight and untangled.

I have done my repair, and this is the result. I am happy with that since it is the first time I weld something on the car.

Soon I will patch some wings and a door that has a hole in it. The target is not to use any filler before painting these since I have seen that it is possible.

Try to cut your patches more accurate mate, you make it harder for yourself having big gaps to fill, also move a bit faster when you are welding as you are getting a large build up in one place and all it does is make work as you have to grind it all off, play with the current settings and wire speed settings on a scrap piece and see the different effects that you get and you will know which one is best, those welds on the end of that sill don't look like they are penetrating to me, they are just sat on the surface and if you grind it flat it will fall apart?
Put two bits of metal together edge on and weld it, then turn it over and see if the weld has gone through to the back.
There is a good welding tutorial on here, have a look at that too.
