    No slag to clean off.
    Fun aspect of fluxcore, the flux shell helps hold in heat more than spray arc potentially resulting in better weld properties.
    When welding AR plate with plain steel wires it may be a bit moot, but a slower cool on a bitchy material like AR isnt going to hurt ones chances...

    Good to know, but on a postioner, with a preheat torch, and multiple passes,
    I suspect we really don't need the flux blanket.

    But I see your point about a rapid quench, will file it away for future.

    I'm really surprised the OP was able to pull this off with the small power supply.

    The size of that thing makes your workholding look like a 1/4"-20 through Unistrut!
