1926The ConTESSI brothers, Aldo and Giuseppe, importers of engineering goods from Germany see the potential and future development prospects of oxy-acetylene equipment and devote all their energies to the promotion of new metal cutting and welding methods. 1935Their proven experience encourages them to manufacture a series of innovative equipment which quickly dominates the market in preference to the German equivalent.
1940Increase in demand necessitates the transfer to the new larger factory in Sestri Ponente.The production process is restructured and the first task is to ensure immediate availability of all spare parts for customers, The war makes it very difficult to get hold of rare metals but it does not stop work. 1946The post-war period finds ConTESSI ready for recovery. Their blowpipes have an immediate application in demolition work and the subaqua version help to free the ports from the floatsam and jetsom of war not only in Italy but also in Normandy.The miracle of feverish reconstruction sees ConTESSI active in new markets. The success of its new equipment extends.

For ladle and tundish discharge opening operations.
Same charachteristics as the lance holder but with the advantage of combining the safety device and the shut off valve in one compact unit.
