In the transportable unit (15) are incorporated a compressed-air driven ejector (11) connectable to a suction mothpiece (3), a filter (12) downstream of the the ejector for cleaning the air sucked inwards through mouthpiece, and a blow-out aperture (13) for outlet into the atmosphere of cleaned suction air mixed with compressed air. Upstream of the ejector the suction device is fitted with a primary regulator (10) which controls compressed air flow to the ejector. - A branch pipe is provided to conduct a part of the compressed air upstream of the ejector for feed to the hand grip (4) of the soldering piston (16) for cooling. A secondary regulator (8) controls the flow of the diverted compressed air to the soldering piston hand grip. The filter is formed as a noise damper for the ejector, and the suction device is fixable on a transformer for the soldering piston. |
