ABSTRACT:
An electric arc saw and a method for operating the saw for cutting or slitting metallic objects by melting a narrow kerf into the object. The method provides for determining the minimum threshold current that is necessary to initiate the cutting operation. The normal cutting current exceeds the threshold current and during the cutting operation the blade is advanced through the object at a speed which is continuously monitored and varied as required to maintain the current flow between the blade and the object substantially constant. The arc saw is constructed so that cuts in three mutually perpendicular directions can be made. The blade is mounted to a vertically disposed, hollow piston that reciprocates in a cylinder mounted to and movable along a cross-head. The piston can be pivoted about its axis to align the blade with the different cutting directions. Electric busbars and power lines for rotating the blade extend through the hollow interior of the piston. The blade itself is relatively thin and slightly dished-in so that it assumes a flat configuration during operation.
