To enhance the compatibilities to multi-types of fiber cutting machines, ISUN-18G integrated RS232, AD Control connection interfaces.
ISUN-18G has remarkable metal cutting performance on a variety of metal materials, such as Steel, Carbon Still, Galvanized Plate and some highly reflective materials like Aluminum and Brass.
Furthermore, our 1500W fiber laser source is even able to process the non-metal materials Marble.
The CW / Single Mode 1500W Fiber Laser, ISUN-18G has exactly the same appearance dimensions as our ISUN-12G. However, the cutting speed has a dramatic enhancement, for regular metals such as Carbon Steel and Stainless Steel, or even for high reflective materials Aluminum and Copper, up to 60%-80% for metals less than 8mm in thickness. Therefore, it is a great option for the upgrades of 1000W fiber laser cutters.
