The "CG1-30H" portable automatic gas cutting machine is a new product developed and manufactured by Warwick. 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 capacity of the machine have been greatly improved. For example, the moving parts, the upper and lower moving seats, the fire mouth clamp, etc. are all made of copper materials, so they are not easy to break or dent. The worm gear is made of bronze and is durable.
