Hi everyone, it seems hard to figure out where the problem is when your IPL/laser handle doesn't work normally and shows simmer fails in control system. Here are some solutions for you. Firstly, if your IPL handle has worked for a long time and already shot for more than 30,000 shoots (different handles have different shoots guarantee), please change another IPL handle to have a try. It is mostly due to the lamp [...]

(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 the power supply,  is damaged. (2) Phenomenon: Short circuit on power. (a):Rectifier bridge is damaged. (b): There is [...]

(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: (a): SG2525 is damaged; (b): The circuit around the SG2525 is damaged, showing as a result of welding [...]

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 cable but confirmed the line of  pre-burning feedback link  is normal (the light is not lit). If it can't be [...]
