This model is a double-light combination model, which increases power. The laser head of the machine has its own fan and built-in air pump. Heat dissipation of turbine blower, low noise, more beautiful and good effect. Control the start and stop of the fan and pump according to the laser intensity, increase the life of the fan and pump, or control it manually. Suitable for customers and friends who are interested in cutting or carving. Carving wood, plastic, bamboo, etc. can reach a depth of 3 mm.Features:Deeper and Cleaner CutsEquipped with blower, the large and stable air blows away the smoke and debris generated during laser work, which helps to cut faster and deeper and improve laser efficiency, thus saving your time.Clean and Smooth Cuts: Using air to blow away dirt and quickly reduce the temperature of the cutting material surface to prevent deformation and discoloration due to high temperature, ensuring smooth lines, complete patterns and clean material surfaces.Built-in Air Pump: No external pipeline and separate pump are needed, so the noise is low. Turn on the air pump, and the cutting and carving effect will be better.Multi-control: Control the start and stop of the fan and pump according to the laser intensity, increase the life of the fan and pump, or control it manuallyAdjustable Installation Position: Metal Plate for adjusting the mounting height is included in the package. It allows the laser head to move up and down according to your installation height requirements.Application: Suitable for customers and friends who are interested in cutting or carving. Carving wood, plastic, bamboo, etc. can reach a depth of 3 mm.Description of carving material:1.
