David -
An additional point to Don's answer, You should ALWAYS match the MASS (1/32" - 1/4" typical in increments of 1/64") and PROFILE (screwdriver, single flat, conical, flat conical, etc.) of the Soldering Handpiece Tip to the work being performed. This is true for irons, desoldering/suction handpieces, as well as tweezers. TEMPERATURE is the third variable in the Soldering Triad. The most common mistake I have seen, is that novice and beginners will "turn up the heat" on the adjustable temperature soldering stations. That is often the worst step they could take -- damaging the underlying board. and component.
