2) Recommended Gas Pressure in CNC Flame Cutting Machine:

a) Preheating Oxygen in the range of 0.5~ 1 MPa;
b) Cutting Oxygen in the range of 1.0~ 1.2 MPa;
c) Acetylene or Propane cutting gas around 0.25 MPa;
3) Preheating for Ignition: To start on flame cutting in the machine, first turn on gas line of preheating oxygen. The duration of preheating depends on the Max. thickness of steel plate for cutting: The thicker the plate, the longer the duration of preheating;

2. Cutting Torch Height Controller and Auto Ignitor in CNC Flame Cutting Machine:

Shown in the above 3^rd and 4^th Photos:

2) Flexible Configured Cutting Torch of in the Machine:
Flame cutting torch has variations on its form:
a) CNC control cutting torch: Controlled with CNC, for performing shape profile cutting. Usually 1 or 2 pieces workpieces can be cut out at the same time. When cutting 2 pieces, it can be either identical, or mirror opposite 2 finished workpieces;
b) Strip flame cutting torch: Controlled with A.C. relay or CNC, for carrying out slit cutting. Usually several pieces of strip plates can be cut simultaneously, and width of each piece of strip plate can be varied, by adjusting on distance of 2 adjacent strip cutting torches;
c) Triple flame cutting torch: Controlled with A.C. relay or CNC, for accomplishing bevel cutting on edges of steel plate. This is used in butt welding of sheet metal plates, when thickness higher than 15mm, to get full fusion on welded seams;
This helps making CNC Flame Cutting Machine becoming comprehensive applied and vital important 1st Operation equipment:
