Hardened ni200 is a different animal. It will bite you if you show it your pliers or cutters [emoji14]I haven't personally worked with Ni200 wire yet but from what I've read it's temperamental and requires a lot more attention to contact points than other wires. If it were mine I would clean all the contacts on the 510 and make sure the positive pin protruded enough to make a good solid connection and I would make certain that screws holding the coil were good and tight. I know Rip recommended grub screws on one of his videos. I may be wrong but I think some of the problem comes in when the wire heats up and expands & contracts when it cools back down. I've seen some contact coils being used with Ni200 but if I were having problems I would make sure each coil was not making contact with any others. Hope that helps.
Now seriously, it's much easier to work with that stuff. 28g hardened ni 200 is harder than kanthal of the same width. Only catch is that when you cross it's limits, it will snap sooner than kanthal and after a week in use, ni 200 is much more brittle and less user friendly at cleaning and rewicking than kanthal.
More than once did I want to rewick and just adjust a little bit the used coil and... snap... There goes the coil :s
