Dear Current Administrators of TBA, Stop erasing posts and topics. All of you. As a regular of TBA who loved it dearly, you have no idea how much it kills me that so many topics were left to the trash without member consent. And it wasn't just drama posts -some of you deleted any post that you didn't like, from roleplays, from anything...you deleted the entirety of A Very Potter Roleplay, as an example. As the creator of that roleplay, I realize it was somewhat of a failure, but the fact that it was erased without my consent is upsetting, and there were a few members who enjoyed it. I realize that there were some things posted on TBA that many of us are not proud of. Drama and the like. But even with that drama, TBA was so, so, important to me, and others. Yet, certain moderators have ignored this and have erased topic upon topic -that showed in the Administrator history. Even if you say it was only a single topic or a single post, the forum has been trimmed down. You say this is only "cleaning up the forum," but it's erasing our history, and I won't stand for it. To those of you who've returned to this forum only to remove things periodically, please stop. It simply isn't fair to those of us who are nostalgic and like looking back, and I know I don't speak of myself alone. With all due respect, LL.

First, if the medium frequency electric furnace is opened before it starts,
The water and circuit should be checked every time before the machine is opened. Confirm that all water pipes are open to water and check whether the circuit has abnormal screw loosening and so on.
Two. The medium frequency electric furnace is opened.Vacuum Metallizing Machine For Helmet Visor
Connect the power of the medium frequency electric furnace cabinet. According to the control power supply, the power indicator light is controlled, the main circuit switch is closed, and the power supply is controlled. The DC voltmeter should display the negative voltage. Then the power given potentiometer is swirled slowly, and the meter is observed, and the DC voltmeter indicates an increase.
1. when the DC voltage is zero, the median frequency voltage, the DC voltage and the active power are increased at the same time, and the medium frequency sound is heard to show that the starting is successful. The power of the positioner can be swirled by the active power to the required power.
2., when the DC voltage is zero, the three frequencies of the intermediate frequency voltage, the direct current and the active power go up and go up, and the normal intermediate frequency sound is not heard. It means that the starting is not successful. The potentiometer should be screwed to the minimum and then restart.
Three. Reposition of medium frequency electric furnace:Car Type Quenching Furnace For Large Parts
If overcurrent and overvoltage occur during the operation of the equipment, the fault indicator light on the door panel is lit. The potentiometer should be rotated to the minimum, "reset" and then restarted. When overrun or overpressure occur during operation, you should not be busy with the restart of the equipment, check the equipment, and there are hidden dangers such as short circuit and fire.hot sale high quality vacuum furnace with competitive price
