Firstly, if your IPL handle has worked for a long time and already shot for more than 30,000 shoots (different handles have different [...]

(1) Phenomenon: Charging shows ZERO V while feedback is correct. (a): The damage output is probably too high, please test the 358 pin 7 with weak 12V, it can be confirmed that 358 is damaged if the  voltage is greater than 2 V. (b): The comparator board, used for controlling the charging and discharging of [...]

(1) Phenomenon: There is no light Please observe the LED indicator on the IGBT board under weak current test. If it is flashing, maybe it's due to the bad quality of the absorption circuit, resulting in line burst with a large current. If the LED is always off, then maybe the reasons are as  follows: [...]

Simmer is mostly determined by the upper power. However, in some cases, the simmer fails is due to the pre-burning feedback link doesn't work. So if it is the first time your clients complain such a problem, please make sure that they have already not only checked the basic connection like to reconnect the 10-pin [...]

The maintenance  basically can be divided into two: pre-sale and after-sale. The former is mainly due to the product quality such as reverse welding,  incorrect assembly and so on. This has seldom occurred among our products as the production system is rather mature. However, in case it happens, we will be responsible for it totally include [...]
