Huawei Gas beetle cutting trolley is a oxygen flame gas cutter. It is supplied with a main aluminum body, 1pcs flat rail, 1pcs cutting torch assembly, 1 set of circling-cutting parts and 3pcs propane or acetylene cutting tips. This beetle cutting trolley is widely used because of its simplicity, low price and easy operation.
The differences between CG1-30 and CG1-100
The main differences between CG1-30 and CG1-100 is the quantity of cutting torch assembly. CG1-30 has a single cutting torch, however, CG1-100 has double cutting torch. Both machines are semi-automatic oxy-fuel cutting machines, and multi-use machines with Acetylene as its flame gas.
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 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 Huawei Gas 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 Huawei gas cutting trolley is with big control plate. However, if you want to get more competitive machine, small control plate and without quick valve are available.
How to select the wanted cutting tips?
Different sizes of the cutting tips, different cutting thickness. First confirm the needed cutting thickness, then select the corresponding cutting nozzles. See below detailed parameter of G02 （acetylene）and G03 （propane）tips.
