According to different structures, CNC plasma cutting can be divided into portable CNC plasma cutting machine, desktop/table CNC plasma cutting machine, and Gantry CNC plasma cutting machine. If we want to cut large size metal, such as 2m*6m, 2.5*8m, 3*6m, we need to use a gantry CNC plasma cutting machine. But for some customers, they cannot afford such a machine because of their limited budget. So we designed a portable gantry CNC plasma cutting machine, so that it can cut large-size metal, but also with a preferential price.
