In addition to these easy to follow instructions, you must always be sure to follow the torch manufacturer's operating procedures. First - before you attempt to light the torch follow these checks:

Make sure regulator pressure adjustment screws are backed out! Make sure torch valves are closed! Stand away from front of regulator Separately and slowly open the oxygen and acetylene cylinder valves Adjust regulator p/a screws to tip pressure settings Open/close torch valves separately and fine tune pressure settings on regulators Depress cutting lever and adjust pressure if necessary Lighting and adjusting the torch (with a positive/equal pressure mixer): Separately purge both oxygen and fuel gas lines Open fuel gas valve 1/2 turn Ignite flame with striker Increase fuel gas flow until flame leaves end of tip and no smoke is present Decrease until flame goes back to tip Open oxygen valve and adjust to neutral flame Depress oxygen lever and make necessary adjustments Shutting down the torch (with a positive/equal pressure mixer): Close oxygen torch valve Close fuel gas torch valve If the torch/regulators and gases are done being used for a while, follow these procedures:

Close oxygen and fuel gas cylinder valves Separately purge oxygen and fuel gas lines Make sure all regulator gauges read 0 Back out regulator pressure adjustment screws! If you are using in a commercial environment, report any damage, etc. to your supervisor The procedures for using a Harris torch with an injector mixer for alternate fuels vary slightly from the information listed above. These procedures can be found in our alternate fuel section. There you can also find informative procedural and application videos.Your nearest store doesn't match your preferred store.

By adding oxygen gas, torch outfits can produce flame temperatures of 5,620 degrees. A torch outfit is extremely versatile: this single piece of equipment creates its own portable heat source and can be used to cut, heat, weld, and braze various metals. Before electricity was available in rural areas, this was the only type of "welder" available to the farming/ranching community. The basic torch outfit consists of two high-pressure cylinders (one apiece for oxygen and acetylene) and two corresponding pressure regulators. A dualine hose transfers oxygen and acetylene from the regulators to the torch handle.

The torch handle can hold a cutting attachment, welding tip, or heating tip (the heating tip is not included with all basic torch outfits). If you are cutting with the torch, you also need a cutting tip that attaches to the end of the cutting attachment. The cutting tip controls the thickness of metal being cut, along with the gas pressures set at the regulators. All torch outfits that use oxygen and acetylene reach the same working temperature of 5,620 degrees. The size of the cylinder does not affect the temperature of the flame. It affects how long the flame will last (the burn time). To get their projects done, you will need proper safety gear. Safety goggles (Minimum Shade #5) protects your eyes while you are using the torch. Welding gloves protect your hands. You will need a hand-held striker to create the spark to light the acetylene and a cylinder cart to hold the cylinders and accessories securely. Types of Torch Outfit Processes Cutting is the #1 most widely used process of the gas torch outfit.

The cutting attachment hooks up to the torch handle and holds the cutting tip. By burning acetylene enriched by oxygen, the attachment and tip heat the metal to critical temperature. At this point, the cutting oxygen lever is depressed, delivering a stream of oxygen that cuts the metal. The advantages of gas cutting It is portable (can be taken anywhere and used). It is able to cut thick material with a range of cutting tips (sold separately). It requires a low skill level and is easily mastered. The Disadvantages of Gas Cutting The oxygen-acetylene gas, once combined, will only cut iron-based (ferrous) steels. The process can distort thin metals unless correct cutting tip is used. Heating is the #2 most widely used process of the gas torch outfit. The gas heating tip (also known as a rosebud or MFA) does not come with all basic torch outfits, but is usually sold separately. The heating tip attaches to the torch handle. The tip has multiple holes that allow several flames to exit the tip.

These flames can heat a large area of metal very quickly to allow bending or straightening. The Advantages of Gas Heating No other tool can heat metal so quickly. The Disadvantage of Gas Heating Heating tip uses a tremendous amount of oxygen-acetylene. Welding/fusion is the #3 most widely used process of the gas torch outfit. The gas welding tip attaches to the torch handle. The flame heats the base metal to its fluid or puddle state. At this point, the gas welding rod (copper coated steel) is dipped into the puddle. The rod fuses to the base metal, creating the weld as they become one piece of metal. The steel welding rod must match the steel base metal in order for true fusion to occur. The Advantage of Gas Welding The Disadvantages of Gas Welding It is a two-handed process that requires a high skill level and takes practice to master. Only works on iron (ferrous) based steels. Brazing/adhesion is the #4 most widely used process of the gas torch outfit.
