Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a weld fume recovering device capable of reducing a frequency that a pre-filter is left without being cleaned by adopting a structure by which the pre-filter is simultaneously cleaned when a dust collecting tray is cleaned. SOLUTION: A hose 3 which sucks fumes scattered in electric welding is connected to the main body 20 of a weld fume collecting machine 1. When a blower motor 23 which is provided within the main body 20 is driven, the inside of a tank 28 which is arranged in the upper side area within the main body 20 becomes negative pressure. A main filter 24 is arranged in a suspended state within the tank 28, and a drawer type dust collecting tray 26 is arranged in the lower side of it. The pre-filter 25 is integrally assembled to the dust collecting tray 26 and is together detached when the dust collecting tray 26 is detached from the main body 20. Also, a connecting tube part 46 which connects the hose 3 is attached to an opening and closing door 44 which covers the dust collecting tray 26 from the outside.
