Removalof flux residuesBrazing flux residues can be removed:• mechanically• by brushing in hot water• by quenching the brazed parts while they are still hot, or• by pickling (bath temperature approx. 40°C)When quenching, take care that the base material and the brazed joint do not takedamage through change of structure, brittleness and stresses etc.To remove flux residues after brazing with pickling, we recommend the following<strong>FONTARGEN</strong> products for the dip-pickling-procedure:• FONTEX for steel parts• FONTEX P or FONTEX NE for non-ferrous metalsParticularities:• The residues of F 400 NH are non-soluble. If necessary, removemechanically.• The flux residues of F 600 C and F 600 CC can be removed by drybrushing or by washing with alcohol, petrol, Tri etc.07/08/SR/0137
Safety precautionswhile working with fluxesIt is normal that brazing fluxes (with a few exceptions) contain aggressive substances.Nevertheless, their use is absolutely harmless if the elementary safety precautions,familiar to every welder or brazer are provided and observed. The most importantprecautions are:• Fluxes in liquid or paste form should be applied with a brush, fluxes in powderform by dipping the hot tip of the rod or by sprinkling from the container. Avoid allcontact with the skin; this is particularly important in case of sensitive skin or openwounds. Wash hands carefully after work is completed and before meals.• Do not inhale the fumes produced during work. The primary requirement in thisrespect is an adequately ventilated work-place.The following rule – of – thumb can serve as a guide:Max. amount of brazing flux used per hour =Volume of workshop m³5 g/hourAssuming the workshop is of normal height (approx. 3-5 m, depending on flood space).The following indications provide a guide-line:A well ventilated workshop suffices for occasional brazing work. A larger, well ventilatedworkshop, approx. 4 m in height, will be adequate for small series by manual brazing.For large series production, carried out manually or with brazing machines, fumeextracto r devices should be provided at the work-place.07/08/SR/0138
