Oxygen LPG vs. oxygen acetylene

Oxygen mixed with a fuel gas is one of the most widely used industrial thermal cutting processes, because it can cut material that is up to 250mm thick, is cost effective, and can be used either manually or mechanically. The two most widely used cutting fuels are LPG (propane) and acetylene, with acetylene being seen for years as the industry standard. However, recently many have questioned whether acetylene is better for cutting than propane or LPG and a debate in oxy-LPG vs. acetylene has emerged. Below, we compare the two and look at the advantages and disadvantages of each, so you can decide where you fall in the oxy LPG vs. oxy acetylene debate. Oxy LPG advantages • Propane has a greater total heat of combustion • Oxy propane is easy to obtain and cheaper • Propane is more stable. Oxy LPG disadvantages • Propane produces a lower flame temperature • There is increased pre-heat time • Propane flames are less focused and therefore piercing is slower • Propane can’t be used for gas welding because it doesn’t have a reducing zone • In terms of oxy propane vs. oxy acetylene, propane is often used when cut quality is not essential. Oxy acetylene advantages • Acetylene produces the hottest flame temperature for oxy fuel cutting and welding • The hotter temperature creates a quicker piercing of materials • Oxy acetylene can be used on sites with no power supply • It is quite a versatile process and can be used to weld most metals. Oxy acetylene disadvantages • Acetylene weld lines are rougher in appearance and need more finishing • Acetylene is unstable and expensive • Regarding oxy propane vs. oxy acetylene, there are more safety issues with oxy acetylene, because there is a naked flame. Oxy LPG vs. oxy acetylene – it's your call! Whichever side you choose in oxy lpg vs. oxy acetylene, don’t be sucked into charging rental costs on gas cylinders you’ll only [...]

Rent free welding gas for all your DIY needs

Do you find that obtaining the gas you want for high calibre home welding is a challenge? Perhaps you’re struggling to find top quality gases in the quantities you need. In these circumstances, why not opt for the rent free welding gas we provide? Rather than having to drive miles to source the gas you’re after, only to find that the size or type you want isn’t in stock, why not use our hassle free, economical service to obtain the gas you need to get the job done properly? Argon, oxygen and carbon dioxide In addition to selling these gases separately, we also stock an argon/oxygen/carbon dioxide 5:2 mixture. Ideal for MIG (metal inert gas) welding, we have over 30,000 cylinders in the market at the moment. Oxygen is well-known to improve the arc and reduce metal tension, giving better results than simply using argon on its own. For TIG welding on stainless steel or aluminium, we recommend pure argon to get the right outcomes. Range of different sizes to meet your needs We know that if you’ve only got a small welding job to do, there’s no point in buying an enormous cylinder of gas. Our smallest size, C, can usually be dispatched to you using Australia mail – no fuss and no rental, and it’ll be with you quickly. For larger sizes (D, E and G), we can provide delivery within 25km of the CBD in Sydney, Brisbane, Adelaide and Melbourne. We supply gas regulators and other equipment If you haven’t got all the necessary equipment to get your welding job completed successfully, we can help. We stock a wide range of welding essentials which we are happy to supply if needed and if we don’t have the goods we will direct you to one of our partners who will have it. If we deliver in your area, we will drop them off at the same time as your gas, saving you time and [...]
