The actualtime consumed, including shifting the beam, was 33 oxygen consumed cost $.623, the Pintsch gas cost $.018, andthe labor $.22. The actual cost for similar work with the old process of chip-ping and drilling for the same total length of cuts was $ cost of cutting with the equipment was thusless than one-fifth the cost of cutting by drilling and IVIodel B Cutting Torch The following table serves to illustrate what has been ac-complished in cutting steel with the Oxy-Pintsch cutting equip-ment. The results given in this table were obtained underservice conditions by means of hand cutting with the model -Atorch without a guide. Considerably better economy can be ob-tained where mechanical guiding is permissible: Tipnumber 1112 Thicl:ness of steel ^in. V2 in. 1 in. 2 in.
