Exactly right 👍

Flux core is actually incredibly strong. It’s used it some heavy industrial/structural applications.

I used my HF 90A (converted to DCEN) to convert my HF motorcycle lift from a manual hydraulic jack to an electric powered hydraulic cylinder. The welds have to hold up to 10,000# of shear force and are holding well. Flux core doesn't make the prettiest welds but they are strong. I'm strictly an amateur welder, and until I got this welder, haven't welded since high school about 100 years ago. I'm convinced that if someone can't get a good weld with flux core, its not the machine's fault.

I flux welded 2 chain hooks onto my tractor bucket. My tractor has a maximum lift capacity of 1,300 lbs. I was moving a boulder that my tractor could barley lift and was actually tipping the back wheels of my tractor off the ground...and the 2 chain hooks I used to strap the boulder to my bucket held, did not show any stress, etc. This was all with only a 110v machine....I have no more fears of using my flux core over my 220v stick welder for small farm equipment.

A very sad outcome when the owner wasn't aware of what was happening until it was too late.

That dog has definitely been around a welder a lot. Didn't even flinch with the noise or sparking. My dog would have been freaking out and cowering in a dark corner for the next 3 days.

My first welder and the one that I use most of the time is a flux core welder, once you get the speed, technique and rhythm right it's all good. Everything I have welding with flux core remain strong even under heavy use. Even on my hay trailer.

Flux core is also used outside a lot because you can still weld even if there is a mild wind blowing. MIG won't work in a mild wind without setting up barriers. MIG is strong, clean, and easy - nothing against MIG. Flux core absolutely has its place and is great for a hobbyist that is willing to spend the time learning it.

Good video. I've had a flux core at home for miscellaneous maint and hobby stuff. I'm not an accomplished welder meaning I have to read the directions on the settings and practice each time I need to use it but when I do get something welded it is welded meaning the welds don't break.

I've also found that if I do a root pass and layer two more beads in the fillet, the weld will hold despite crushing the base metal with a big hammer.

I often use my genny to weld, when you first spark off, either stick or mig, it takes a second for the generator to add fuel and bring the RPM's up under the sudden load, but once the bead is running, I think it is actually smoother than under grid, and it doesn't pop my breakers as often, since my welder and air compressor are on the same circuit. Also, my interior lights sometimes go low when I start welding, and my UPS on my computer complains about a voltage drop, which isn't good for some electronics.

FLux core works outside better than just gas, since under high winds (I live in KC, where the wind only stops blowing just before the tornado hits), the flux doesn't blow off exposing metal for instant oxidization. Dual shield is great too, since you have the flux plus gas. You can also use flux to get in tight spaces, since you can weld with the outer cup off.

And sees lots of abuse. Jumps and all I did however. As always over build. I cut the swing arm at and angle two of em to get the 4 inch stretch, and sleeved it from the inside drilled holes and plug welded. I have welded with Flux core all angles, upside down sideways verticle horizontal and flat. Pacfice practice. Nothing wrong with Flux at all

No problem! I'll get on it asap. These machines can do a ton of stuff if used properly. I'll have more videos like this coming soon

for someone who knows how to weld with flux core it is every bit as good as mig. If you think about it, it's like arc welding. Arc welding the rod has the flux on the outside of the electrode, flux core it is on the inside. you get a thicker rod with arc, but with flux core if you aren't going too fast you are able to put more wire into the weld. So with flux core you have to be a better welder.

I use fc 308L on stainless water heater tank and water keep seeping out at around 30 psi. Eventually have to take it to shop for repair with gas. It could be I'm new to welding but normally I don't have issue with regular weld.

It works just fine, as long as you’re doing it right. If you’re making any of a number of errors, you will, of course, get a bad result. The same applies to all welding processes.

It seems that you stirred up a hornet's nest with comments about flux-core. I built my trailer with flux-core and I'm not even a professional welder. In fact, I've never used a gas MIG. I might go months without doing any welding, then do a little bit or a lot, so it's not worth me having gas. I would also agree that flux-core works well with a light wind, as I do my welding outside. One disadvantage of flux-core is that the wire is more expensive than plain wire. However, for infrequent use, it works out cheaper than having a gas bottle and getting it filled. The main disadvantages of flux-core are the fumes and having to clean the slag. A gas welder produces a clean weld (with no slag) and doesn't produce the fumes that a flux-core welder produces, so a gas welder is much better for indoor use.

Very true! Don't need anything too elegant for what I'm doing! Now maybe when I build that launch vehicle to take me to mars I may upgrade 😂

I've done both with my Lincoln 225 and prefer welding with gas if for no other reason is that it makes a much cleaner weld if you dislike or don't want splatter cleanup. For welds that are out of sight or in the field, the flux core is fine and just as strong but mine were never pretty, looking more like bird tu#ds

I think flux core actually welds hotter than MIG - not sure. It is messy but other than that it's fine. The people complaining about it probably get lots of slag inclusions in their flux core welds because they aren't doing it right. I think it's just harder to do right than MIG so people don't really learn how to do it right.

My only comment is to just be aware that "most" gasless FCAW filler materials contain 1% aluminum. Aluminum really like oxygen. The function of that Al, in the filler material, is to "scavenge" out oxygen. This means it is to prevent/keep oxygen out of the solidifying weld puddle (to make your weld NOT look like an Arrow chocolate bar). A side effect of that 1% aluminum is "real poor" impact values. So, NEVER EVER use gasless FCAW wire to weld up a trailer hitch, for example. Yes, gasless FCAW gets used a ton out in industry (in the right places). Yes, you can get 70,000 ultimate tensile strength (UTS) out of a gasless FCAW weld. No, it cannot be used in every situation where MIG, or even stick welding is employed.

Is it safe for dogs to be near you while you weld?

Would a flux core welder be ok for a frame rail for a car ?

Yes but it depends on what you're welding exactly and how thick the metal is. Thinner metals like mopar subframes are really easy to weld with smaller wire like .030 because theyre so thin but chevy frames are much thicker so you'll need more heat and thicker wire like .035

@@NightWrencher hey thanks for the quick reply, I have a 83 cutlass and it needs the right side replaced , I thought maybe a flux core welder might do it . New sub here

Doesn't penetrate. I have problems blowing holes I stuff all the time. Plentry of heat/power there.

I purchased a mig welder but when I saw the price of the gas bottle i was like nah I'm getting flux core, i don't like stick welding for all of the "starting the arc", having to change electrodes and all of that, it's strong enough for me

Flux core is the every-mans process

Get some eye protection for old yellow there before he goes blind

Can you tell me make/model of your welder (3500watts)
