& nbsp; The cutting seams of parts with different materials and specifications are inconsistent, which is easy to cause large or small size during cutting. Only test cut 100 before each cut × For 100 rectangular samples, adjust the slit compensation value according to the samples, and adjust the cutting speed according to the cutting conditions of the parts, so as to ensure that the size and surface roughness of the parts meet the cutting requirements< br /> & nbsp; When the NC cutting machine is cutting, the peak current will affect the normal discharge voltage, but it has little effect on the workpiece thickness and cutting direction. When the peak current is determined, the fluctuation of discharge gap voltage in normal discharge state in machining is relatively small. If there is a short circuit in the discharge gap, the influence on the peak current in machining is the largest, followed by the workpiece thickness, and finally the cutting direction< br /> 1. Do not touch any switches and buttons with wet hands to prevent electric shock< br /> 2. Do not check the line or replace the electrical components with electricity, otherwise it will cause electric shock or injury< br /> 3. Maintenance personnel with corresponding technical qualifications can repair the equipment only in strict accordance with the technical requirements of electrical maintenance. In case of accidents< br /> 4. Do not touch any electrical components in the electrical cabinet and console when the machine is powered on or running< br /> Prevent damage < br / > 1. After each cutting, the cutting gun shall be raised to a higher position to avoid damage caused by hitting the steel plate< br /> 2. Do not touch any electronic device in the control cabinet when it is charged to prevent electric shock< br /> 3. When moving the machine beam, ensure that there are no people or other objects in front to prevent collision accidents< br /> Prevent fire < br / > 1. The air source of the cutting machine shall be far away from the open fire, and carbon dioxide or other corresponding fire extinguishing devices shall be placed around it< br /> 2. The working raw materials used by the cutting machine are flammable gases, such as acetylene, propane, liquefied gas and so on< br /> 3. The operator shall control the fire in time to avoid fire. Therefore, regularly check whether the whole gas circuit is well sealed < br / >
