What should I do if there is voltage and no current after the eksperimento nga electric furnace is started?

It is found that there is voltage and no current. The reason for this situation is that the heating element is broken. At this time, turn off the power and check carefully. The common heating elements are GWL–XB, 0Cr25Al5, 0Cr27Al7Mo2, Cr20Ni80, SiC, MoSi2, Td, Mo , W, zirconium dioxide, lanthanum chromate heating elements, etc. During the inspection, you need to check one by one according to your own experimental electric furnace configuration, and then find the damaged heating element to replace it.
