Abstract

Fume extractor for welding torches uses protective gas linked to the torch and has suction pipes which draw the fumes and smoke from the welding zone to a filter located in front of a side-channel compressor used to provide the suction, and a second filter can be fitted on the outlet side of the compressor before the air is blown out to the atmos. The novelty is that a suction pipe is used which consists of several sections and the side-channel compressor has a max. rating of 1 kilowatt(1.36 horsepower). The suction pipe pref. consists of a first stage with a bore of 10-20mm. and a second stage with a bore of 20-40mm. used with a compressor having a rating of 0.5-0.75 kW, and with a gas washer located in front of the first filter, both filters using cartridges with a pore dia.
