The Differences Between CG1-30A and CG1-30B

The main differences between CG1-30A and CG1-30B is the working rail. 30A is with “H” rail, 30B is with hole rail. The rail is different, the driving wheels and directional wheels will be different, the price also will be different. So please show us the exact needs, then can supply you the correct pug cutting trolley.

Functions of Beetle Cutting Trolley

The surface cutting roughness could reach to 12.5 and needless to cutting processing further on common occasion. The mainly function of this flame cutting machine is to do straight linear cutting. It has an additional function to do circling-cutting as well as V shape beveling. What’s more, If more facilities added, it can even be used for quench and plastic welding. For an example, adding a oscillator with CG1-30, then can do welding job.

Details of Gas Cutter Beetle Cutting Trolley

The cutting torch assembly with 2 different hoses to distinguish the connected hoses, red color and blue color. There is a quick valve to control the cutting functions, not need to open or close the small valves to adjust the gas for working. The control plate has two different designs, one is big, the other one is small. Our standard machine is with big control plate. However, if you want to get more competitive machine, small control plate and without quick valve are available.
