Flux core is ugly, and the wire costs more than solid core wire.
So relative to standard MIG, its sucky and nobody likes it.
The problem is, nobody is actually comparing it to Stick, because nobody fricking uses stick. Its dudes who have high end MIG machines running gas calling it shit.
They are also calling Stick garbage too.
Fluxcore is actually cleaner and prettier (marginally) than stick is.
I have heard flux core is best for welding outdoors because it produces its own shielding gas at the weld. Gas MIG can have the gas blown away by wind when working outdoors. So there is an application for it. Also it's useful to include with a new welder because you can play with the welder right out the box before finding a gas bottle.
t. Also have a Hobart 140 for automotive, used the included flux core to weld back on a broken 1/4" steel tab for a sway bar end link. Never personally tried welding outside though.
When you're one of those dumbshits who think buying a 100 bucks harbor freight shitbox makes them a welder yeah.
Get leagues ahead of the competition by knowing how to actually set up the machine
I used a hobart handler 140 with flux for a long time, and managed to do some exhaust work, but it sucked and I had pinholes (I am not by any margin a good welder). I swapped to 75/25 and have never had that problem again on anything. That said, If I'm doing exhaust work...I'm just buying a tig welder, or taking it to someone who has one.
It's just really hard to control with your hands and a cheap-ass welding machine with cheap ass electrodes won't ignite properly at least than, lets say 60 Amperes.
This, it's possible with skill and good DRY electrodes, but slow. Making a 1/8 sleave in two halves and gringing back to pristine metal on exhaust will help if its all you have.
It will be extremely difficult and ugly
Use some comically small 1/16" or similar rods.
You would unironically be better off just buying a cheap fluxcore machine
>fluxcore
Isn’t that the worst welding technique?
it is if you have no idea how to weld
No, stick welding is by far the worst welding technique for exhaust. By a large margin

the hot glue of welding
gross, but effective
if you're mostly interested in hobby craft

It works, but you need to know what to do, have a professional welding machine and very thin sticks which again require alot of skill.
Protip: You can oxy-acetylene weld or braze exhaust.
Stick is bad for thin material
