Tungsten carbide thermal spray powder is a type of powder material that is used in thermal spray processes. It is composed of tungsten carbide particles, which are combined with a binder material to form a powder.

Thermal spraying is a coating process that involves heating the powder material to a molten or semi-molten state and then spraying it onto a surface to create a protective or functional coating. Tungsten carbide thermal spray powder is known for its hardness, wear resistance, and high melting point, making it suitable for applications where extreme wear or high temperatures are present.
DC resistance tester considerations
1. Select the appropriate range based on the size of the measured transformer resistance.
2. DC resistance tester instrument malfunctions, or error start and other anomalies, should press the "reset" key to terminate the test process, so that the system initialization, reset display when the display "0000" a few seconds after the display of the current value.
3. When testing the no-load regulator winding, unless there is a short-circuit switch, it is not allowed to switch the tap-changer before the discharge is completed.
4. Before dismantling the measuring line, be sure to wait for the charge/discharge indicator to return to zero and the audio prompt ends.
About DC Resistance Tester Internal Battery Description:
There is a rechargeable battery pack inside the instrument and a charge and discharge protection circuit is provided.
When the external AC 220V power socket is connected, the internal battery is charged, and charging is not controlled by the switch.
When the battery is full, the charge-discharge protection circuit will automatically reduce the charge current and control the charge voltage to protect the battery pack but charge it. Continuous charging for a day or two will not damage the battery pack.
When the battery voltage of the DC resistance tester battery pack is lower than the rated lower limit, the output of the battery pack will be cut off and the whole machine will not work to protect the battery pack from discharging.
