That's strange then.
About the only other things that come to mind are using enough pressure on the electrodes, making sure the nickel surface is clean and free of any contaminants (like oil), and maybe the electrode material. I use solid copper wire for electrodes on mine and get great results with .15 nickel, but I have not tried 0.2 nickel.
