Frequency-sensitive varistor several problems processing method

The frequency sensitive rheostat is factory-connected to the 90% tap of the coil. If the motor is connected to the rheostat, one of the following conditions can be adjusted according to the following method:

1. The starting current is too large (greater than 2.5 times), the start is too fast, you can try to increase the number of turns, the tap to 100% turn, the effect of the start current is reduced, the starting torque is reduced simultaneously.

2. The starting current is too small (less than 2 times) The starting torque is not enough, the starting is too slow, you can try to reduce the number of turns, the tap to 80% of the number of turns, the effect of the starting current increases, the starting torque increases.

3. If the machine is restarted after stopping for a period of time, the motor may be jogged several times due to heavy mechanical load and difficult to restart. After the machine is turned for several times, it can be used normally.

1.Quality pass Germany TUV testing. Tuv testing is third safety certificate company,.more authoritative.

2. This system welding machine use Surface Mount System to install electron component and the main PCB board is single .So this system could make the machine`s quality is very stable. Rise the quality consistency.   

.

3.The power tube of the switch use germany infineon only.The PCB board thickness size is 2.7mm. 

4.The insert component use Taiwan KSS.

5.The aluminum web wing is more bigger and weighter than normal.

6.Passed EMC certificate and get the EMC certificate. According to IEC 60974-1 standard.

7. Our machine`s input voltage is auto change between 85V-240V.So could work under any voltage. Like japan 110V or America 110V AC. Like European 220V-240V AC. Like Brazilian 110V/220V together AC.

8.CEL. Could weld Cellulose electrode easy.

9. Welcome any customer to make your design. We have advanced exploit troop.

10.PFC (Power Factor Correction is more than 98%. So according to energy conversation ,environmental protection and low-carbon.

11. VRD make no-load output voltage under 24±2V, But when arc strike twinkling could rise working output voltage.So this technique could have more physical protection.
