Device for drilling and cutting with improved electrode enables simpler construction and easier handling and can therefore be constructed as the portable handheld device, i.e. it can be used for cutting and drilling under the water. It consists at least of the following parts: tank for oxygen under pressure, oxygen inlet hose, coupling, holding fixture, body of the device, valve, tubular electrode holding shank and tubular electrode, provided that the tubular electrode is made of iron tube, into which are inserted the alloy and non-alloy rods which burn down in the oxygen mixture during the drilling/cutting procedure. Essential part of the present invention is a tubular electrode for cutting and drilling using burning method in the oxygen mixture which is made of iron tube, inside of which there are non-alloy metal rods and alloy rods with content of aluminium and magnesium. |
