Tips for fluxcored?

I've found this also. Better penetration and a longer duty cycle. Not sure why though.

As I understand it, the wire is the same diameter, but it has fillers in it (the flux center) so there is less metal than a solid metal wire. As such, its like burning a smaller wire (perhaps like running 0.030 vs 0.035 or 0.045?).

The AWS study I found was dated in the mid-90s. It is quite likely things have improved since then. I won't suggest a nozzle is required. But if you got one...

For me (big subjective) it helps on a windy day, probably because I can angle it to protect. My glove would probably do the same. So to the OP...I de-emphasize my original advice on the nozzle. Whatever works for you.

But, don't run downhill on verticals you need to hold fast. Anyone wanna argue that one?

You can weld pretty heavy plate with .045 flux-core. There may be less wire but there is iron powder and other elements to make the weld stronger. Flux-core also gets deeper penetration unless you're in spray transfer at high amps with solid wire. The dual shield flux-core comes in as many variations as stick electrodes for just about any type of steel.
