CNC Plasma Torch Height Controller Kit (T.H.C): with torch height controller kit, the plasma cnc machine can cut metal sheet which is uneven, the plasma torch head will automatically rise and fall as the material surface goes up and down; without T.H.C controller, the plasma cnc machine can only cut flat sheet.
