One of the engravings shows the Oxy-Pintsch cutting torch,model A. There are but two hose connections, one for Pintschgas and one for oxygen. The Pintsch gas and oxygen for theheating flame are controlled by two lever valves, making aquick and accurate adjustment possible. The oxygen for thecutting is controlled by a third lever valve which can be read-ily opened or closed, as required, by a slight pressure of the. Model A Cutting Torch with Guide thumb. The cutting tip of this torch is of annular form, withthe oxygen cutting jet located centrally. Since the cutting jetis surrounded by the heating flame, it performs its proper func-tion irrespective of the direction in which the cutting tip isadvanced. This cutting tip also incorporates a novel designwhich causes the heating flame to develop inside of the tip. Theheating flame, thus protected from the entrained air, is positiveand effective in action, greatly facilitating adjustment for work-ing conditions. The illustration shows the cutting torch equippedwith a guide, the use of which is recommended wherever per-missible as an aid to accurate cutting. The model B Oxy-Pintsch combination cutting and weldingtorch is litted with cutting and welding attachments, and hasall the advantages outlined in connection with model A formetal cutting. The welding device illustrated can be used satis-factorily for repair work to casting
