Oxy-Acetylene Welding Equipment Setup and Usage Quiz

Oxy-Acetylene Welding Equipment Setup and Usage

• Oxy-acetylene welding equipment setup requires a systematic and definite order to avoid costly damage and ensure personnel safety.
• Gas cylinders, especially acetylene cylinders, should be stored and transported in the upright position to prevent fuel starvation and flashback in the system.
• Prior to installing the regulator on a gas cylinder, the cylinder shut-off valve should be briefly opened to blow out any foreign material that may be lodged in the outlet.
• The red hose with left-hand threads should be connected to the acetylene pressure regulator, and the green hose with right-hand threads should be connected to the oxygen pressure regulator.
• Flashback arrestors should be installed between the regulator and hose to prevent flashback, and fittings should be tightened only enough to prevent leakage.
• The oxygen cylinder valve should be slowly opened to check the contents in the tank, while the acetylene cylinder shutoff valve should be slowly opened just enough to get the required flow.
• A 25-inch lens, available with an elastic strap, provides protection from flying sparks and accepts a variety of standard shade and color lenses. It can be worn over prescription glasses.
• In the past, lens shade for gas welding was selected based on the brightness of the flame emitting from the torch, with the darkest shade showing a clear definition of the work being most desirable.
• A new green glass lens was developed in the late 1980s by TM Technologies, designed especially for aluminum oxy-fuel welding, eliminating the sodium orange flare completely and meeting ANSI Z87 1989 safety standards.
• Torch lighters, also called friction lighters or flint strikers, consist of a file-shaped piece of steel and a replaceable flint, producing a shower of sparks to light the fuel gas.
• The use of proper filler rod is crucial for oxyacetylene welding, adding reinforcement and desired properties to the finished weld. Rods may be classified as ferrous or non-ferrous, and their diameter is governed by the thickness of the metals to be joined.
• Welding rods are manufactured in standard 36-inch lengths and in diameters from 1/16 inch to 3/8 inch, and all filler rods should be cleaned prior to use.
