High-power static induction transistor (SIT) is a high-power electronic devices, the same as its symbol and the transistor, the role of high-frequency welding machine prices are similar, but it is mainly used in high-power converter or conduction control applications, it has the following characteristics: a "positive turned" feature, when the positive gate voltage is "0 V", SIT in the conductive state, while when applying a negative gate voltage, then in the off state. Fast switching speed for high frequency band. A high input impedance voltage-controlled device, so with a relatively small drive power can control larger power. High-frequency induction heating machine installation steps: 1) Place the main pay machine: General is the host (operation control unit) in the high-frequency welding machine, pay machine (power output machine) in the next place. 2) connected to the main pay machine Hydro: fine accessories in two pipes, straight up and down the waterway mode is turned on. Then the attached two cables, connect the red red, black black fashion circuit switched connection. Be sure to tighten the supply of high-frequency welding machine, can not have contact with undesirable phenomena. Pay machine connected to the main ground. 3) electrical connection: The machine is a three-phase power supply (380V), the three red wires were dedicated access phase knife or air switch (65A above). Followed by a good ground. 4) Water connection: cooling water used for the machine 0.1Mpa-0.3Mpa (about 1-3 kg). Please users to choose a 370W single-phase (220V) pumps and a water tank or pool (depending on the time and effort to select continuous volume high-frequency welding machine, can be installed, if necessary, a small cooling tower). Plumbing the pump outlet and inlet connected to the machine, the machine outlet with a hose will return back to the pool, to achieve the cooling water circulation. 5) install an induction loop: The metal heating the workpiece shape, size, selection and installation, fixed induction loop. Note that the induction coil can not have a short circuit.
