It cannot hurt to perform the setp again as per the book, as a double-check.
Remember, an arc needs voltage to form (as in "jump across the gap"), not current. Current only comes into play once the plasma arc is formed.
Having no experience with TIG I really can't answer the question directly, but I hope what I wrote helps.
