Extremely cold weather or low temperature will cause damage to the optical part of the laser. And it is difficult to repair. Therefore, at low temperatures, the water in the water tank should be drained and replaced with a special antifreeze. Our laser machine special antifreeze is a light-colored liquid. The product uses M3 ultra-film anti-rust technology and Modify2000 composite modification technology, which has excellent anti-freeze, anti-boiling, anti-corrosion, and anti-scaling functions. There is no need to add other rust inhibitors during use, and it can be directly diluted by adding water according to a certain proportion according to the temperature. The minimum freezing point can reach -50ºC.
