The "CG1-30C" portable automatic gas cutting machine is a new product developed and manufactured by Warwick Company. The internal structure of the machine is reasonably designed and the appearance is beautiful. Under the guidance of customers, a number of technical and process improvements have been made. Due to the use of new materials and strict requirements on parts processing technology, the operability, durability and heat insulation of the machine have been greatly improved. This machine is equipped with a battery power supply that can realize automatic cutting in an environment without an external power supply. The battery is durable and can work for nearly 12 hours after each full charge. It can also be connected to an ordinary municipal power supply (AC220V) and driven by the built-in transformer output for cutting operations.
