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 [...]

Rent free welding gas bottles: the benefits

rentfreeg@s 2016-12-14T16:08:23+11:00 Categories: rent free gas bottles, Welding Gas|Tags: bottle rental, buy your own mig bottle, cylinder costs, no cylinder rental|

As most who have experience with welding gas bottles will know, rent can quickly start adding up. This is the case whether you’re using them intermittently or every day. The following reasons are the 3 major benefits to choosing a rent free welding gas bottle for all your metalworking needs. 1. Catering for professionals and the home handyman Renting a welding gas bottle may be a viable option for an amateur metalworker performing one-off projects. However, if your use is consistent, then the benefits start to disappear. With renting, you keep it around for the days you do need it, but the days you don’t you’ll be paying for it anyway. This is a waste of money that could be better spent. By purchasing a rent free welding gas bottle, you’ll pay a one off cost, and apart from re-fills, the days you’re not using it, you won’t pay a cent, leaving you much better off in the long run. 2. Rent free welding gas bottles for different types of gas One week, you’re paying rent on an argon gas cylinder, the next oxygen, then CO2 and helium. At times, if you choose to rent, you’ll find yourself needing multiple types at once, and paying likewise. If you know which cylinders you need, you can purchase them outright. Therefore, on the weeks you need two types, you will have two ready to go, without the complicated processes of returning and renting cylinders on a consistent basis. This will save you ample amounts of time and money, making your metal working experience easier and stress free. 3. Domestic shipping Welding gas bottles can be quite heavy. Many rental places require you, the customer, to pick up and return the goods, or come with ridiculously high shipping costs. By purchasing a welding gas bottle outright, we come to you and we have one price. When your cylinder is empty we come back again, collect the empty and replace it with a [...]

How does a rent free welding gas bottle work?

rentfreeg@s 2016-12-14T16:22:31+11:00 Categories: rent free gas bottles, welding gas bottles|Tags: Argon gas in cylinders., bottle volumes, Cylinder volumes, cylinder weights, Oxygen cylinder contents|

You’re a welding business that uses a lot of gas, and you’ve been renting your bottles for years. But, with rental prices escalating, you’re now beginning to wonder if there’s a more cost-effective solution. The good news is that you can now buy a rent free welding gas bottle, and save. How does it work? You’ll firstly buy the ideal type of gas cylinder for your needs in a size that is the most economical for your use. Gas cylinder types are varied, but the most common are Argon, Co2, Helium, Nitrogen and Oxygen. Sizes typically range from 20 kilograms up to 95 kilograms in weight. And we also have the C size which is 6 kilograms full of gas. These rent free gas bottles are full at the time of purchase and delivered to your door. Once you’ve used your gas, and you’re nearing the end of your bottle, you’ll then contact your gas supplier and order a refill. Your refill will then be delivered to you as soon as possible. Do all gas bottles come in the same sizes? The size of rent free welding gas bottles varies depending on the type of gas you are purchasing. Argon gas and Argon 5-2 gas (for MIG welding) cylinders come in volumes of 0.6m3, 1.7m3, 4.0m3 and 8.7m3, as does Oxygen. Nitrogen, however, comes only in 0.6m3, 1.7m3 and 8.7m3 volumes and Helium in 0.5m3, 1.3m3 and 3.4m3 volumes. CO2 gas is available in 1.8kg, 6 kilograms, 22kg and 31-kilogram volumes. How does the cost of a rent free welding gas bottle compare to renting? The initial outlay to buy your rent free welding gas bottles is more expensive than renting gas cylinders. However, you will only need to purchase your gas bottles once, as they have a lifespan of 10 or more years. The cost to then refill your rent free welding gas bottles after you’ve used the gas is minimal, compared to the rental charge [...]

Types of rent free welding gas bottles available

rentfreeg@s 2016-08-11T11:55:47+10:00 Categories: welding gas bottles|

There are many different types of rent free welding gas bottles that are on the market. Some of the most common are Argon, MIG gas, Nitrogen, CO2, hydrogen, helium, and oxygen, as well as propane. These gases can be used by themselves, or may be mixed with other gases to use on various materials. Types of rent free welding gas bottles Argon, Oxygen and Co2, as well as Helium and Nitrogen gas, are available in rent free welding gas bottles. These gases can be used to weld many material types. Argon Argon gas, which is colourless and odourless, is used in the casting industry to flush defects from molten materials. When used in metal fabrication, this gas generates an inert gas shield. When blended with Co2, Helium and Oxygen, Argon enhances the characteristics of the welding arc. Oxygen This gas is also colourless and odourless. Oxygen supports welding cutting operations when added to other shielding gases, and can be mixed with plasma cutting gases to use on carbon based steels. CO2 Mostly used with Argon gas, Co2 is a shield gas ideal for welding. This gas can be utilised in a vapour state to prevent the atmospheric contamination of molten metals during the arc welding process. Helium Helium is a nontoxic and inert gas. As such, this gas is non-flammable and has high heat conductivity, making it ideal for inert gas shield creation. Helium also prevents oxidation when welding aluminium, copper, and stainless steel, as well as magnesium alloys. Nitrogen This gas in its pure form is used for tube welding, particularly stainless steel. Nitrogen also increases the capabilities of plasma cutting and heat treatment. When added to Argon, Nitrogen can be used in gas metal arc welding, also known as MIG welding. Rent Free Gas can supply you with Argon gas cylinders, Oxygen and Co2, along with Nitrogen and Helium gas cylinders. So, no matter what type of materials you’re looking to weld, we [...]

A wide world of uses for cheap helium tanks

rentfreeg@s 2016-08-02T18:15:39+10:00 Categories: Uncategorized|

Did you know that helium is the second most abundant element in the entire atmosphere? That fact alone may not be much use to you, but when it is pressurised and put into helium cylinders, like the ones you can buy from Rent Free Gas, helium is not only colourless, odourless, non-corrosive, non-toxic and non-combustible, it’s also very handy for industry and your DIY projects. Here’s a few ways to put your cheap helium tanks to good use: 1. Balloons The most obvious use for your cheap helium tanks is to keep children happy at birthday parties by having colourful floating balloons all around the party. The balloons float because helium is the second lightest known gas. 2. Coolant Because helium can be cooled below its critical temperature without condensing into a solid, it is useful in the area of cryogenics. While that may be the case, it’s unlikely you’ll be using your cheap helium tanks bought from Rentfree gas to make superfluid helium for superconducting, quantum computing or x-ray crystallography – but you never know! 3. Welding Helium is one of the noble gases that is commonly used as an affordable inert gas for welding, acting as a shielding agent against oxygen and water. 4. Detecting leaks A lesser-known use for your cheap helium tanks is for detecting leaks. It is a good tracer gas not just because it is relatively inexpensive for this application, non-toxic and non-flammable, but because its small atomic size means helium escapes through the tiniest of gaps. 5. Growing crystal Another major use for cheap helium tanks is to create a controlled atmosphere for a range of chemical processes, one of the biggest ones being growing crystal. This was even done by a group of Japanese scientists at zero gravity! 6. Lasers Again, it’s unlikely you will use your own cheap helium tanks for creating the sort of lasers that are used for barcode reading, but this element is used extensively [...]

Why helium gas can be a health hazard

rentfreeg@s 2016-07-20T10:05:16+10:00 Categories: Helium Gas|

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 [...]

Why are the world’s nitrogen sales so high?

rentfreeg@s 2016-07-14T17:28:39+10:00 Categories: nitrogen sales|

Nitrogen sales throughout the world are higher than you might imagine, with this abundant chemical element being a crucial component to life on earth. It’s found not just in many everyday situations, but in every single living thing, with nitrogen sales not limited to usage in foods, fertilisers, poisons and explosives. Nitrogen uses across different industries Nitrogen is used in many industries, with this naturally occurring, extremely abundant, colourless and odourless component also coming in a liquid form which looks similar to water. Many nitrogen uses relate to the production of ammonia, which accounts for most of the world’s manufacturing of various fertilisers. Nitrogen is also used in the production of refrigerant gases, the manufacture of plastics and textiles, and in cleaning solutions used in households across the world. Food production Through the production of fertilisers, nitrogen sales also contribute directly to the world’s production of crops and food. Nitrogen has important health benefits, too, as almost all pharmacological drugs contain this substance. Nitrogen is also used by the health industry in the form of nitrous oxide as an anaesthetic, while in the gas form it helps to conserve egg, blood and sperm specimens. Nitrogen gas is also used to help respiratory patients, in a combination with oxygen to make it healthy to breathe. Computer industries also contribute to the world’s nitrogen sales, as microchips utilise it for cooling. Entertainment & military uses Entertainment also contributes to nitrogen sales, as most paintball guns are now powered by this gas rather than carbon dioxide. And nitrogen sales also keep high performance motor racing and aircraft tyres on track and performing to their highest standard. Nitrogen is also connected with the military, with some aircraft fuel systems utilising it, while it is also commonly used in steel production. Nitrogen sales makes good sense Most nitrogen sales are connected with industry use. It is very effective in destroying toxic liquids and vapours, and as a catalyst, a bleaching agent and rocket [...]

Oxygen bottles for sale have so many uses

rentfreeg@s 2016-07-07T14:10:24+10:00 Categories: oxygen bottles for sale|

Rent Free Gas has oxygen bottles for sale that can be used for a multitude of purposes. In fact, oxygen – a colourless and odourless gas – is used for such a wide range of commercial, industrial and other uses in both its gas and liquid forms that oxygen bottles are among the highest of all the chemical sales in the world. Oxygen bottles for many sectors When this gas is harnessed and stored under pressure in a bottle, it can then be deployed for use in many sectors. One crucial use for oxygen bottles is in the field of medicine. Oxygen bottles can be used by people who struggle with their breathing or have other health issues, such as heart conditions or infectious diseases. As a crucial element to life on earth, human beings can live without food and water for a while, but not for more than a couple of minutes without oxygen. Oxygen bottles used by industry Oxygen bottles are also used within the world of industry, such as for welding. Some materials that will not easily burn in normal air will burn in oxygen, helping greatly with combustion. Oxygen bottles can help those who cut and shape metal, powering the flame torches that cut through metal with high precision. Oxygen bottles can help the welder produce temperatures of over 3,000 degrees C, but these flames also help with brazing and glass blowing and will allow users to cut through concrete and bricks. Rent Free Gas’s oxygen bottles for sale are not used by NASA! The oxygen gas bottles available for purchase through Rent Free Gas would not, however, be used in the powering of rockets and missiles, but these are among the hundreds of other uses of oxygen around the world. NASA’s space shuttles, for instance, were powered by fuel tanks holding half a million litres of liquid oxygen – just a little more than the small, medium and large oxygen bottles for sale [...]
