A fluxer comprises a spray head (15), a reservoir (3) for the flux (9) and a feed line (11) for feeding flux from the reservoir (3) to the spray head (15) by pressurising the reservoir with an air supply via a line (7). A return (12) line is provided from the spray head (15) so that cleaning fluid (9′) can be fed from a reservoir (3′) via line (11) and returned to a waste reservoir (19). A spray head has an electromagnetically operated piston (53) for spraying flux. The piston (53) is biased to a first position by a spring (49) to close a spray outlet aperture (63) and is moved against the force of the spring (49) by the electromagnet (71). |
