diode laser stack warranty

The key to protect the laser stack and never let the stack break, keep best cooling are the condenser and the water pump.
most laser stacks broke for unstable water pumps

The key is clean, stable water, which is done by filter https://www.sg-hz.com/water-filter-10-microns-p0788.html and a powerful and stable water pump, better with the Italian pump https://www.ipl-elight-shr.com/italian-pump-p0720.html, or this stable Chinese pump https://www.ipl-elight-shr.com/high-lift-24v-dc-brushless-centrifugal-home-brewing-cider-pump-p0710.html, those of DP60 https://www.ipl-elight-shr.com/search/?Keyword=dp-60 are noisy and break more. The diode modules break by themselves are very few, but more by the water circuit.

La clave es el agua limpio, estable, lo cual se realiza por filtro https://www.sg-hz.com/water-filter-10-microns-p0788.html y una bomba de agua potente y estable, mejor con la bomba italiana https://www.ipl-elight-shr.com/italian-pump-p0720.html, o esta bomba china estable https://www.ipl-elight-shr.com/high-lift-24v-dc-brushless-centrifugal-home-brewing-cider-pump-p0710.html, las de DP60 son ruidosas y se rompen más. Los módulos de diodo se rompen apenas por si mismos, sino más por el circuito de agua.

国外有返修的手柄,整个手柄退回越来越难,海关经常可能让收货人出示价格证明,有清关费用,而且需要交进口税。其中一个办法就是客户把激光器拆出来,单独把激光器返回,目标小许多,运费少大半,也能避免关税。李工,安装,也就是拆开手柄, 取出激光器视频讲解 注意点 有无?
