The primary factors that affect the cutting ability are the laser module's power and the auxiliary air pump. To achieve a strong cutting ability, you can consider purchasing a 33W laser module and upgrading to the gas auxiliary system ACMER C4 (30L/min). Additionally, using a honeycomb plate to assist gas circulation can be helpful. For those who primarily focus on engraving scenes, our standard electromagnetic silent air pump that can produce an air output of 25L/min will meet your engraving needs. Any unauthorized modification of the air pump to increase its output may increase the risk of fire, unless an inert gas is used.
