Utility model for torch handle with arrestor. Death of Hermann Stahl. The management of PERKEO passes into the ownership of the founder's son, Eberhard Stahl.
Production and sales of the first portable small-size welding, cutting and brazing equipment. This marked the birth of PERKEO on-site equipment which became firmly established on the market; a great relief for every fitter which meant he could now take his welding or brazing equipment with him to the workplace, putting an end to any maneuvering of large cylinders or even extensive dismantling work.
PERKEO is active in the technical standards committee for pressurized gas systems at the German Standards Committee.
The first external testing in the fields of cylinders for compressed gases, liquefied gases and gases dissolved under pressure is carried out by the Technical Inspectorate (TÜV) of Baden.
Utility model for portable and wheeled small-size equipment for oxy-gas welding, cutting and brazing - PERKEO on-site equipment and systems.
Eberhard Stahl passes on the management of PERKEO to his daughter and to the holder of general power of attorney, Yassine Hönes. Decision to introduce quality monitoring is passed and realized. It is a project for the following two years to draw up a new quality management manual including the description of the quality management system and the organization.
PERKEO requests inspection with the DVGW (German Technical and Scientific Association for Gas and Water) and voluntarily harmonizes the products with the latest DVGW regulations. This technology and consequently FMEA and CAQ are introduced. Quality assurance in receiving is modernized, the results of all quality assurance measures are statistically evaluated.
Prokurist Yassine Hönes übernimmt das Unternehmen und wird alleiniger Inhaber und Geschäftsführer.
The company moves to its current premises in Schwieberdingen.
