This is especially true of machinery and equipment, as they all experience a certain amount of wear and tear during operation, and components are also susceptible to damage, which involves many factors. For example: voltage stability, frequency of use, hardness of cutting objects, etc.
1. Make sure the voltage is standard: when the input voltage is too high or too low, the resistance wire will be heated, and the service life of the heating wire will be shortened;
2. The cutting template is within the allowable range: the cutting machine cannot cut under the condition of working thickness;
3. The resistance wire cannot be used for a long time: the cut resistance wire melts the sample under the heat generated for a long time, so that the temperature of the resistance wire is too high or locally overheated, which affects the life of the resistance wire;
4. Keep the resistance wire clean and dry: During the cutting process, a part of the melt will be attached to the resistance wire, which will seriously affect the cutting accuracy and local heat-resistant wire during the cutting process. Carefully check before and after each cutting;
5. Maintain a uniform speed during the cutting process: During the cutting process, the descending speed is too slow, so that the temperature generated by the resistance wire is not easy to release, so that its own temperature rises, which seriously affects the service life. Excessive cooling speed makes the temperature generated by the resistance wire unable to melt the template, and it is in a fastened state, which easily leads to bending deformation of the resistance wire and uneven local heating.
