Welding advice, Can a cheap flux welder do what I need? Options

[Deusexmachina77]

I have to weld in a new front trunk pan replacing the hole left from an AC unit. I have taken two MIG classes. Beside being a newbie, I have other limitations to consider.

I don’t have access to a 220 line.
I’m inexperienced.
It would cost me $1000 to have it professionally done. And I don’t want to buy a bunch of equipment for one job.

Can I use a flux welder? There a couple cheap units at Harbor Freight (under $150) on sale right now. What don’t I know that I should know?

Thanks (IMG:style_emoticons/default/welder.gif)

Well, that depends what you want. If you want to make it look like the trunk was never replaced, buy a finger sander off of amazon and make that weld line disappear! If you're good with what you've got and you've run a light underneath to ensure there are zero pinholes, then you can prep for paint. I'd feather back the paint a bit more and hit it with epoxy primer. You can use seam sealer here if you want. It might look better than the weld, as is, and provide protection.

I'd personally use the finger sander but it's a matter of what you want to look like in the end. Good Luck!
