The cutting blowpipe or torch may be either of high pressure or low pressure system. The ﬂame when welding or cutting welding goggles must be worn. Lesson 14 Welding Cutting And Brazing INTRODUCTION Many welding and cutting operations require the use of compressed gases.

You can also get straight head for other but the 90-degree cutting head is the most common one. The high pressure blowpipe uses cylinder acetylene or propane as fuel gas which can be the mixture in the head or in the shank of the cutter or blowpipe. Oxy-fuel welding and cutting processes require gases at specific pressures and regulators will generally be used to reduce the high pressures of storage cylinders to those usable for cutting and welding.

Different lenses are recommended for the various processes. Oxy Acetylene Welding Set Up and Pressure Settings Chart. The tip of a welding or cutting torch is where the action is see Figure 1.

Welding tips usually produce positive pressure higher than 1 pound per square inch PSI and are used at equal pressures of acetylene and oxygen. WITT offers a large range of pressure regulators and outlet points for almost all technical gases pressures and flow rates. The first stage of the regulator releases the gas at a constant.

You can also use a 75 and 45 degree cutting head which can be used for beveling heavy steel. Shade 4 Oxy-cutting and gouging. The ame temperature Propylene is used in production welding and cutting.

Open Regulator Oxygen and Acetylene set until the pressure matching with what do you want or. The injector type is used when fuel gas pressures are less than 1 psi. In this type Oxygen at high pressure pulls the fuel gas into the mixing chamber.

When compressed gases are consumed in the welding process such as oxygen- fuel gas welding requirements for their handling storage and. The low pressure blowpipe with injector mixing can be used with natural gas at low pressure. The gas hoses caused by welding or cutting at incorrect pressure settings or from blockage or overheating of the nozzle for example by operating with the nozzle too close to the material Flashbacks can result in extremely dangerous cylinder ignition and must be prevented by proper use of working Flashback Arrestors.

WELDING AND CUTTING TIPS. Prevent it like professionals If you are looking for flashback arrestors non-return valves safety relief valves or other equipment - you can rely 100 on WITT gas safety equipment. When performing welding cutting andor brazing operations in areas on or around Acutely Hazardous Materials which are included in a Process Safety Management PSM Program a hot work permit is required.

The equal pressure type is the most common and is used with fuel gas pressures that are above 1 psi. Oxy Acetylene Cutting Pressure Settings Chart.
