Correct. I don't spend any more time with fluxcore than absolutely necessary, so I don't claim to be the ultimate authority but I am certain about the reversed polarity.

 

Maybe you should ask around, find some people who know welding. They will all tell you 308 is the way to go.

 

Someone has been asking to see my work, so here's a link.


I built the big brown launcher, and lots of parts in the plane too.

 

I hope a mod comes in here to clean up all this pecker comparison so the thread can have some actual technical merit. There is about 4 pages of pointless crap that could have been addressed in one single reply rather than 10 separate ones.

As far as using fluxcore goes, it is not only used in cheap welders. It is used for most outdoor welding where SMAW (stick) welding is not used. A MIG welder is useless if there is any wind to blow away the shielding gas so I don't buy into the hype that fluxcore makes an in-superior weld. An in-superior welder make a poor weld. If your welder is penetrating properly and you are using the proper fill material it really doesn't matter what the machine is either.

 

Hmmm, got about a hundred pm's for those covers, guess I wont make you one. I know im a good welder, your the only one who seems to disagree, and you are a noob. I would like to know exactly what makes it look like crap? The nice finish? The fact that it doesn't leak like most custom covers do?

 

Oohhhh, wanna se my spud gun.? Haha. I said your OWN fab, like we do, on the garage floor, useful jeep parts. Im not going to keep trying to prove myself to some Jack a$$ anymore, since he is the only one in disagreement.......unsubscribed..

 

Sorry about that, but nobody calls me a noob with impunity. The only thing I said about fluxcore was that 110 welders running fluxcore are notorious for not penetrating.

 

Come on guys, this is TOPIC of the month, not DRAMA of the month. This has gotten worse than my school.

 

This thread has certainly turned into a drama....I was actually trying to find some tips & tricks to welding...only found a couple so far...as for Hobart welders, I bought one from the tractor supply and it works great for welding body panels and yes I run flux core wire....hasn't given me a problem yet and it also works great for heavier metals up to 1/4 " & with great penetration....And I am also a noob to welding and want to learn as much as I can , so I can make better welds....

 

My comment was not meant to be directed at you but merely to shed some light on fluxcore welding being a good method and not necessarily something to be shied away from.

A few more tips:
Do NOT use brakeclean to clean metal prior to welding, the fumes coming off of the weld can be very toxic! Also keep your ground (or positive clamp depending on welding polarity) nice and close to where you are welding. Keeping it close reduces the chance of the voltage damaging electronic equipment. It is also a good idea to disconnect your negative battery terminal.

 

Acetone is probably the best choice for cleaning as it evaporates quickly and cuts grease effectively. You should wear rubber gloves though because it does go through your skin and into your blood.

 

That is what I use also, cheap and always have tons of it around for painting and general parts cleaning.

 

i just learned brake clean does the same thing. goes right through your skin and its a carcinogen. time to double up on glove cause it eats right through them.

 

I have a 110v flux wire welder that i use just for making tabs and whatnot. I would love to use it for body work but the welds come out like total crap. Slag everywhere and i end up burning through metal even on low setting. Is it just that flux wire sucks or could i acctually use this for something more than welding nuts to steel? This is the only welder i've ever used.

 

Thin metal you have to do spot welds and allow area to cool some before starting more spots. Use thinner flux wire its not as clean as mig but done right it works

GEARZ just ran an episode title oem vs aftermarket. half way in he talks about welding lots of great body work info
