For cutting, the set-up is a little different. A cutting torch has a 60 or 90-degree angled head with orifices placed around a central jet. The outer jets are for preheat flames of oxygen and acetylene. The central jet carries only oxygen for cutting. The use of a number of preheating flames, rather than a single flame makes it possible to change the direction of the cut as desired without changing the position of the nozzle or the angle which the torch makes with the direction of the cut, as well as giving a better preheat balance.

Manufacturers have developed custom tips for Mapp, propane, and polypropylene gases to optimize the flames from these alternate fuel gases. The flame is not intended to melt the metal, but to bring it to its ignition temperature. The torch's trigger blows extra oxygen at higher pressures down the torch's third tube out of the central jet into the work piece, causing the metal to burn and blowing the resulting molten oxide through to the other side. The ideal kerfs is a narrow gap with a sharp edge on either side of the work piece; overheating the work piece and thus melting through it causes a rounded edge.

Cutting is initiated by heating the edge or leading face (as in cutting shapes such as round rod) of the steel to the ignition temperature (approximately bright cherry red heat) using the pre-heat jets only, then using the separate cutting oxygen valve to release the oxygen from the central jet. The oxygen chemically combines with the iron in the ferrous material to instantly oxidize the iron into molten iron oxide, producing the cut. Initiating a cut in the middle of a work piece is known as piercing.

Gas Centre Bank System has consisted of various places locating such as main equipment room or, one and more satellite stations wherever welding may be required on a frequent basis,such as the ramp deck. The main workroom is fully equipped with equipments accessories and consumables to perform arc welding and gas cutting and welding; an outlet station which houses and protects oxygen and acetylene regulators; arc welding machine and cable,welding table, The satellite station is equipped with an outlet station, ships cabinet, arc and/or gas welding gear and protective clothing. Also for multiple cylinder supply, additional components include a high pressure manifold with individual manifold valves with non return (check)valves to isolate each individual cylinder. These systems provide safe and efficient operation under all conditions.
