Helium Hire & Delivery to You – Sydney.

Helium balloons are definitely not just for kids anymore. Beautiful helium balloons are being used everywhere. The latest trends in helium balloons are centred around stylish creations using giant 3 foot balloons, balloons with tassels, confetti balloons and letter balloons. One of our customers recently had 3 foot balloons on strings coming out of the pool, and they looked amazing! You can now easily get your inspiration from an abundance of websites showcasing stunning helium balloon decorations such as Lenzo and Pinterest. It is then very simple to source these gorgeous balloons and accessories which many stores deliver to your door at no extra cost. There is a problem though:  How do you get the helium to inflate these beautiful balloons? balloon gas cylinder Party stores are becoming harder and harder to find and those that exist are often not in a convenient location close to you. These stores generally do not deliver or pick up helium tanks. If you can convince them to help you out you will pay a hefty price for delivery.  Of course there are disposable helium cylinders but they are terrible for the environment as they can not be recycled, they might just fill one 3 foot balloon, and we recieve calls from customers who need more gas, as the disposables did not fill all the balloons in the pack. So how do you take advantage of the huge choice of gorgeous helium balloons out there but get your helium too? That is where Rent Free Gas can help you out! We understand that you might not want to buy a helium cylinder of your own so we now offer the hiring of our helium cylinders. We are very happy to bring helium to your door for all of your short term needs. We know how precious your time is. Let us make it very easy for you. Simply choose the cylinder size you need, pick a drop off [...]

Rent-free welding gas bottles for every occasion

Different Gases used for Welding There’s only one thing better than welding gas bottles for your DIY projects – and that’s rent-free welding gas bottle for your DIY project! Welding can seem like an intimidating process, as it involves energy powerful enough to fuse metal - and that has to be bad for the human body if used improperly. But, by taking the time to acquire the right skills and knowledge, carefully practising and using great equipment like rent-free welding gas bottles, you’ll be completing your DIY projects with ease. Rent-free welding gas bottle types When it comes to welding, you will eventually be faced with the question of what sort of rent-free welding gas bottle you will need. So let’s go through the options: Argon Argon is odourless and non-toxic and it occurs naturally in the atmosphere, but in the form of a gas bottle, it creates an inert and clean environment, free of nitrogen and oxygen. When used for metal fabrication, it is a shielding gas, and regularly blended with CO2 and or Oxygen (O2) for MIG welding – but 100% argon can also be used for TIG welding of any metal of any thickness. Oxygen Oxygen makes up 21% of the atmosphere, and is therefore crucial to all life on Earth. Also odourless like argon, oxygen gas bottles are used for oxyfuel cutting, or in small quantities can be added to shielding mixes. Oxygen can also be used for plasma cutting of steel, so an oxygen rent-free welding gas bottle is a powerful tool. CO2 CO2 is yet another odourless gas that can be packaged for a versatile rent-free welding gas bottle, and like Argon & Oxygen, it is non-flammable. In welding, its most common use is in combination with argon for shielding, although it can also be used in its purest state. Nitrogen There may be a lot of oxygen in the atmosphere – but there is much more nitrogen out there. A tasteless [...]

Why helium gas can be a health hazard

Helium gas is a naturally forming element in our solar system and has many uses outside of balloons, including as aircraft and spacecraft fuel and inside technology, including quantum computers and medical equipment, such as MRI machines. Balloons are a must-have party item all over Australia, but can be an expensive option. Using the DIY method and purchasing a cheap helium gas cylinder can cut your costs and provide you with cheap helium gas balloons. Unfortunately, there are some risks associated with helium balloons at parties that are not widely known in Australia. The dangers of inhaling helium gas Popular media often depicts characters inhaling from balloons to get laughs. Inhaling helium gas can change the way your voice sounds as sound can travel almost twice as fast through helium gas as it can through normal air, making you sound like a cartoon character. Party-goers around the world regularly inhale helium to achieve the same effect, and in doing so can unknowingly put their lives at risk. Helium can displace oxygen in your body and cause asphyxiation. Helium gas works in the same way as water does in your lungs when you drown, and even a few seconds of oxygen deprivation can cause serious side effects, including permanent brain damage. Lowering the oxygen concentration in your body by just 18% can be fatal. Inhalation of helium gas can also rupture air sacs in your lungs and cause helium bubbles in your arteries that can travel into your brain or heart causing instant death. Over 75 deaths in Australia between 2005 and 2009 can be directly attributed to the inhalation of helium. Medical risks Medical professionals are concerned about the risks that this simple party trick can pose to unwitting people. Steps are being taken in conjunction with the gas industry in Australia to minimise the deaths caused by inhalation of helium gas. Rent Free Gas is concerned about the misuse of helium, however it is not [...]

Argon and helium gas welding

Why argon and helium gas welding is important When welding, particularly arc welding, it is key that your use some form of shielding or welding gas. Argon and helium gas welding provides more suitable conditions for the welding arc by protecting it from the damaging effects of the surrounding air. If a welding arc comes into contact with heated metal, the oxygen will begin to oxidise the metal. Additionally, nitrogen or moisture in the air might cause the welding to become porous or brittle. All of these factors are undesirable when creating strong, durable welding joints. The presence of welding gas thus improves the surface appearance and geometry of welds, while ensuring arc stability and increased metal transfer. Welding gases also burn off alloying elements and oxide formation on the bead surface. By using welding gas you can increase your overall welding speed. Should I be welding with argon gas or helium gas? The two most common forms of shielding gas are argon and helium (or a mixture of the two). Argon is a naturally occurring non-flammable and non-toxic gas that is colourless, odourless and chemically inert. Argon is particularly effective in protecting weld sites from detrimental atmospheric influences, such as oxygen, nitrogen, and water particles. As such, Argon is commonly used in welding and other high-temperature industrial processes, which often cause non-reactive materials to become reactive. Argon is the best gas for shielding tungsten arc welding with an alternating current (AC). It provides extremely stable and quick starting arcs as well as cleaner welds. Argon gas is also the most commonly used shielding gas for welding aluminium. Pure helium, on the other hand, is used more commonly in direct current electrode negative (DCEN) gas tungsten arc machine welding. Pure helium provides high heats which result in fast welding speeds and deeply penetrating welds. This is particularly useful when creating full penetration butt welds, which are only welded from one side. Argon and helium mixtures also produce high [...]
