Flux core?

O.K. don't want to start shit, or get shit started, would just like to know who has used flux core to do they're frame work. i have never used it on anything, and don"t intend too. but the neighbor just got a 220 and is going by the manual. Sooo who has used Flux core for frame work? good stories? bad stories?

i hear its junk

did my buddies notch and some of a body drop with flux core....WAY back in the day...

i wouldnt do it again...

Flux core can be less hassle then most make it out to be because it can protect the weld in more circumstances then mig, I can't tell you how many times I've been welding with mig and nice breeze comes along or theres just a little bit too much impurities on the metal and then it's got porosity in the weld and looks like shit then I gotta pull the grinder out until I get it to weld clean.long story short is that flux core can be more predictable: It runs hot and strong and creates alot more smoke but just like stick a little bit of paint or dirt aint gonna stop a weld from being strong,alot of slag but the welds can turn out really pretty if you get used to it

I welded my upper bag brackets with it two years ago and haven't had a problem yet.

i think it all depends on the person welding rather than the welder.

let me answer this really easily. stick welding. they still use it. they make ships, tanks, water tanks ect out of the stuff. now i know what you meen about flux core, but stick welding is basically the same thing, just the flux is out side instead of inside. flux core is good stuff, if dont properly. its ugly, dirty, and needs to be wire wheeled to look good. your buddy got a 220 flux core, why is what id ask, but if thats his style great. theres nothgin wrong with it, if welded properly is what i guess im tryin to say

Alright On the flux core topic kool. I have toyota and i've used my flux welder to do all my body work n shit on it and i love it. My uncle came down and welded up my notches w/ it fine(just the corners cuz its made out of box) The welder says it will weld up to 3/8 and i believe it. If I take my time and weld and plate everything for my suspension and weld both sides of what I can get to like brackets and whatnot. Just basically take my time. Should I have any problems?

We used a 110 flux core on the Datsun frame we z'ed last year, and it's still going strong. The flux core burns hotter, so you can get better penetration than MIG at the same power levels (important if you're talking 110 welders!). However, LOTS more cleanup afterwards- that stuff splatters everywhere! I am still using that welder now, but just for tacking things together- if I want a clean weld, I'll have the guys here at the shop do them!

I am a welder by trade working on heavy equipment.Flux cored wire has high tensile strength and better shielding properties.When used properly the weld looks a hell of a lot better than solid wire. But when you run your solid wire at 27 volts like I do with flux core it has the same penetration. I have personally chosen to do my frame and brackets with 1/16 FC and anything smaller with either .45 FC or .35 solid wire. There are too many variables to accurately tell which is better. My advice is stick with your solid wire if thats your skill level.
