If not, I might just get a wired silicone heated bed, stick it underneath the mk2a and call it that. like $200 overbudget now >.<
If the tip goes black, you can sand it until you get to bright metal. (Let it cool first). Keep the sponge damp, and wipe the tip on it occasionally as you're soldering (this can be done when it's hot). Dip the hot tip in flux when it's clean and hot, and tin the tip with solder. For electronics, use the thin rosin-core solder that doesn't require extra flux. Heat the part you're soldering, and if it needs more solder, feed it into the junction between the tip and the hot metal part.
