From what I can recall from watching most of his videos over the years, he doesn't have any fancier vacuum pumps, so it would indeed be a piece of new equipment he would have to buy.
He cycled the argon five times, which is probably plenty without the need for new equipment. He also melted titanium to ensure that any remaining reactive gases were destroyed even after five cycles of argon.
