Are you planning to do future welding repairs? If not it will be cheaper to find a place to have it fixed. As for the pans you can make your own or for $35 a piece buy them from Quadratec.

If the rust is not that bad maybe you can patch them or put diamond plate over them.

I would recommend a 110 welder. I have a lincoln and it works awesome for body work. I've used it a BUNCH for jeep sheet metal. You basically keep going around the piece your welding in so it doesnt get too hot in one place otherwise it'll warp.

You don't need a welder for floor pan replacement. It is much easier to use automotive structural adhesive, it's plenty strong enough if done properly, and much more rust resistant than a weld bead you probably can't seal well (especially if you're new at welding). Details in this post: https://www.jeepforum.com/forum/f8/ga...ml#post6731486, go to that post to see the explanation that goes along with these photos:

I used 120 Amp, 230 Volt Flux & MIG Welder from Harbor Freight Tools and it's worked fine for me.

Try Classic Ind. for your repair panels. Much thicker and better formed than the others.

Thanks for the replies guys. I already have all the floor pans. I just need to intall them. I do not know how to weld but my friends are welders and I can learn. I want to know more about the adhesive. I could save alot of money that way.Also, How do I know how much of the old floor to cut out? I dont want to remove to much and be screwed. Do I need to worry about the tub flexing inward when I remove the floor pans?

If you've followed the link in my post about the adhesive and you still have questions, let me know.

No, you don't have to worry about the tub flexing inward.

i would NOT replace them with adhesive. i just bought my second jeep and the previous owner did this several years ago and now i'm replacing them myself. this time they are welded in. not that hard too. if your going to do it, do it right. as for sealing a weld, you use seam sealer in a caulking gun over top and bottom of all your welds. this stuff hardens and is paintable. if you do alot of trails or mudding i think you'll regret using an adhesive. just my opinion.

I have a similar welder, http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=55525, and mine has also worked great through my entire build. $140 shipped to my door is pretty amazing for how well it has worked.

It all depends on if you have access to a 220v supply. If you do I would go with a 220 machine. It's a lot easier to make a bigger welder work with smaller metal then it is to use a small welder on thicker metal.


PS. What is going on with the http links today?

I do a bunch of welding almost everyday and I'd say use a 110 welder with flux. I've tried a 220 and it just goes right thru thinner metal. A 110 with gas I think would be optimal for welding sheet metal but I just use flux core. For anything but sheet metal tho I use a 220 mig

A 125A-135A MIG is all you need to weld up to 14ga easily. I would definitely recommend a 220V welder if you EVER think you might want to weld anything over about 3/16".
