Yes, flux on a 7018 AC will absorb moisture. Either heat the entire pack in an over for 1/2 to an hour, or if you just need one rod for an emergency, "stick" the rod on scrap metal for about 5 seconds with the welder set on atleast 125 amps. In a few seconds the metal electrode will be very hot and will dry the flux in about 15 seconds.
If you need to weld with 7018, we found that on DC, 7018 AC rods weld much easier than conventional 7018 rods.
