There are 2 ways to resolve this lead "problem".
1)Just replace the powercord.
2) Lop off the connector, cover the whole thing with techflex using a zip tie to hold it at the steamer end. Then put a new connector on (use a Furutech or Oyiade - it will sound better) running the techflex into the strain relief. Now you have a cord that is safer, just don't chew on it!
Or you can just ignore it.
