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.


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.

Can These Gas Cutter Beetle Cutting Trolley Do Circular-cutting and Plasma Cutting?

Yes, they can. Our standard machines are with the circling-parts to do extra circular- cutting, including their main straight-line cutting function. What’s more, the plasma cutting also is available. These CG1-30 and CG1-100 flame gas cutting machines have the same functions as Huawei’s HK-12 cutting beetle, but with cheaper prices.
