Automatic soldering or welding unit for small parts - has hydrogen oxygen gas mixt. plus alcohol gas, if required, fed under pressure to workpiece location

摘要

Soldering or welding unit esp. for automatic processing of small components utilises a stream of pressurised heated gas, more specifically hydrogen and oxygen, which is fed via piping (4) to a torch nozzle (9) directed at the soldering or welding position. The tubular section of the nozzle is eccentrically mounted on the unit relative to its vertical axis (5) about which it is swivable. The solder in wire form (41) is fed from an exchangable magazine (37) via an automatic advancing unit (55). The nozzle movement and solder wire feed are program controlled. The gas mixte is produced by the electrolysis of mineral-free water. Hydrocarbon gas, e.g. alcohol gas, can be fed along with the combustion gas mixture in order selectively to adjust the flame temp.' ADVANTAGE - The soldering or welding head design facilitates compact, intensive action at the soldering or welding points, rapid progression of the individual processes, improved application of soldering flux and the elimination of oxydation reaction during working.
