Default Fluxcore butchery...

Hello Nasoic...

I'm a welding newb and don't really have the right equipment for anything major. I have a 110v mig/fluxcore welder at the moment that I haven't really used for anything other than some spot welds.

I have a catback that needs welded to a downpipe, both a 304 stainless.

Now my questions is, I was going to just fluxcore it (I don't have gas) with .30" mild steel wire (this one)

I know that it will look terrible and will eventually rust. I was planning on grinding it slag off and painting over the weld to prevent rust. Not looking to win any welding awards just want to stick 2 pieces of metal together, bad idea???

try practicing on a couple of test pieces a similar size/thickness that your going to be wanting to weld---that way you can set up the welder correctly without ruining the final work.

It'll work. It won't win any awards for prettiness, but it'll work.

Grab some anti-spatter spray and hit or cover the surrounding areas to minimize the tits that always seem to end up everywhere with the fluxcore wire.

Do small tackwelds, for me, they seem to turn out better than running beads....even when skip welding.

Have at it!

tack welds work good, but I think like four tack welds on the pipe first. Then connect the welds with short beads. Thats how I do it with my mig.

Just get some practice in first I have the same set up just a 110V flux core mig and can turn out some decent looking welds, not nice like a tig or anything but after cleaning the slag and splatter off they look as nice as a good mig weld done with gas.

It'll work. I do it all the time patching up exhaust that I really don't care how it looks with a cheap 110 fluxcore mig. Biggest problem you will have is getting enough heat in it to make a strong weld without blowing holes in the pipes. Cheapo 110 fluxcore migs don't have good controls. Try doing short sections of about 1" at a time on a higher setting.

I used to have a decent gas mig but sold it the last time I moved rather bring it along. For now I'm just using a cheapo harbor freight fluxcore machine to weld exhaust pipes, tack weld body parts etc. It's not pretty but gets the job done.

Get one of these for welding with flux. I use it when I stick weld and if you can weld half decent it will look ok with this when done. A added plus is it will peen the weld to help stress relieve it making it less prone to cracking. It does wonders for removing the little balls that are everywhere when done.

I really like my 110v flux-welder. I've done IC pipes for the Mazda, small patch panels on the King Cobra's fender, hundreds of lil brackets.

I hadn't used it in a while into last fall. and I couldn't get it working properly. I took it to the local welding supply, $65 for a quicky tune up. The guy there who worked on it said he was very impressed with what it could do for a lil 110v flux-unit.

Mine has low-med-high settings. just a 3-way switch.

On your repair, like everyone said. go in short sections. alternate sides to not heat up the areas too much.
