Oxy-Fuel Cutting with Propylene
When fuels are burned in the presence of oxygen, they are able to generate a flame of a higher temperature compared to that of a fuel burned in air. Oxy-fuel cutting makes use of this extremely hot flame to cut metals and it is up to the op... .. .
Storing and Handling Gas Cylinders
Many welding and cutting processes require the use of compressed gases, either for shielding or for fuel. These gases are stored under high pressure, upwards of 200 Bar or 200 times atmospheric pressure, and as such they must be treated with care. If a gas cylinder becomes damag.......
The Many Uses of Nitrogen Gas
Did you know that only about 20% of earth’s atmosphere is breathable oxygen? The rest of the stuff that floods our lungs with each breath (79%) is mostly gaseous Nitrogen (GN or N2) which doesn’t hurt us or hel...........

Health & Safety with Welding Gases
There are many inherent risks of welding and cutting processes, one of which is the potential exposure to toxic gases. In some cases, such as MIG and TIG, welders purposefully use shielding gases to protect the weld pool from contamination by the atmosphere. Most of these gases are not ............
