The Hakko 817-01 Desoldering gun for use with the Hakko's 472D, 473, and 703 desoldering stations. Any station that uses the 807 desoldering iron can use the Hakko 817-01 Desoldering gun/iron. The Hakko 81701 incorporates the same nozzles and filters as the 802 gun or 807 iron. The primary benefit of the Hakko 81701 is to allow operators the choice of either gun or pencil desoldering without having to purchase a separate station (ie. 470D or 472).
