| With just gas, good equipment and a steady hand, you are ready to cut steel anywhere. No electricity or complicated equipment is needed - just you, the metal and the gas. And that's the way it's been since the beginning of the last century.
Oxy-fuel cutting is a combustion process. An oxygen jet burns the metal in a narrow section to make a cut and removes the combustion products (slag) from the kerf. The purity of the cutting oxygen is of key importance for the cutting speed that can be achieved. High purity oxygen means high productivity.
Before oxy-fuel cutting can begin, the steel must be preheated to ignition temperature. This is done by means of an oxygen/fuel gas flame.
The choice of fuel gas influences the cutting process with regard to quality, preheating times and the thickness of the material that can be cut with good results.
Proper storage and supply of fuel-gas determine production efficiency.
The most critical part of the cutting equipment is the cutting nozzle. The performance of a nozzle rises with the increasing exit velocity of the cutting oxygen jet, which in turn depends on the design of the nozzle orifice. Oxy-fuel cutting is used for mild and low-alloy steel in a material thickness of up to a few meters! The surface condition has a certain influence on the cut quality, for example different types of shop primers for temporary protection against corrosion.
Straight cuts, bevel cutting or weld-edge preparation with several simultaneous torches are just a few of the options enabled by this versatile tool. It is also ideally suited to mechanization, reducing operator risk. We provide suitable equipment and help you with installation and set-up. Working with fuel gases and oxygen can be dangerous if the operator does not know how to install, use and maintain the equipment properly. Check for our safety precautions.
Shop primers
Coating a steel plate with a shop primer for the purpose of temporary protection against corrosion affects the flame cutting properties of the plate. Both the type of shop primer and the thickness of the primer film have a strong impact on the loss-of-cut speed, the highest achievable cutting speed without cutting defects, and the formation of adhesive slag.
