What is MIG Gas?

What is MIG and what does it mean? MIG stands for Metal Inert Gas. This is a commonly used term in the Welding industry in Australia. MIG Gas refers to a gas that is inert (inert means 'still') and when we use that word ('inert') with gas it implies that the gas is inactive or non-reactive. So that gas, such as Argon, can be used in the process and not react with the other elements. The MIG Gas is used as a shielding gas to prevent Oxygen and moisture from getting into the weld. MIG Gas Mixtures The most common MIG gas supplied in Australia is a blend of Argon, Carbon Dioxide and Oxygen and this mixtures of the gases vary. There is normally a high concentration of Argon 92-95% with the remaining gas mixture mostly carbon dioxide (3-5%), with a low percentage of Oxygen (1-3%). The MIG gas mixture we supply is 93% Argon, 5% Carbon dioxide and 2% Oxygen. MIG gas advantages Welding with MIG gas is great, because: Welding a large number of metals and thicknesses is easy The welt bead is good Weld splatter is minimised Welding with MIG gas is easy to learn and master. MIG gas disadvantages Welding with MIG gas can be limited for very thick metal MIG gas welding is less portable than arc welding The weld is slightly less controlled than TIG welding. If you have not welded previously or are getting back into the game, remember it is best to seek advice and guidance first. The key areas of interest, are what type of metal are you welding? how thick is it? what is the best Gas for this process? have I got the right equipment? and then always do a test run. Doing some research on the how to hold the welding torch, and the angle, as well as watching some Youtube videos might also be a good idea. Happy welding.

How Do I buy Nitrogen Gas?

Buying Nitrogen Gas  & Own your Cylinder - Sydney  There are many suppliers of Nitrogen gas in Australia. The large gas companies, such as BOC (Linde), Coregas, Supagas & Air Liquide all supply cylinders of Nitrogen. But now you can also buy nitrogen bottles as well as gas. Rentfreegas and Speedgas will sell you a nitrogen bottle, with gas and deliver it to you, within 24-48 hours if you are in Sydney. When that cylinder is empty we come out to collect it, and swap it over, for a full bottle. This swap system works well for cafes, tyre shops, and most nitrogen users in Sydney. Purchasing a cylinder allows you to reduce the cost of paying cylinder rental, never pay rent any more! This "rent free" model helps customers save money on cylinder rental (also referred to as, container service charges). Nitrogen is an inert gas that has many applications across the air conditioning industry, food industry, beverage industry (that is, beer, wine & soft drink) and many industrial applications, including tyres, tools, paint-ball, purging and so on. This shows the versatility of Nitrogen. Our Nitrogen is food grade (99%) and our Sydney prices are below. Nitrogen Sydney Delivered Prices New Full Bottle Refill Bottle C 0.5m3 $220 $70 D 1.6m3 $320 $90 E 4m3 $390 $110 G 8m3 $440 $130 Our Nitrogen bottle prices include the cylinder, gas, GST & delivery in Sydney. New regulators,  We have new regulators available that are single stage, side entry, with dual gauges (high and low pressure) and have a non-return valve with a standard Nitrogen fitting (this is a Type 50 outlet), the inlet pressure is 20,000kPa and outlet pressure is 1000kPa. In Sydney we can do these regulators for $60+GST delivered to you. For interstate customer's the price is $70+GST delivered. Call us now if you have any questions - 0404 677 187.

Buy Don’t Rent – Argon Gas Bottles

Buy your Own MIG Gas bottle With the start of the new year individuals, families and organisations often have new years resolutions or new areas of focus. This new year focus is a good thing and given the excesses of Christmas (and perhaps a little overspending), or the pressure from the boss to reduce costs, finding a saving in the new year is normally high on the priority list. One area we can help with is cheap argon. The rentfreegas model, as our name suggests, means you immediately stop paying rental the day you buy your own argon gas bottle. Now that you own your own bottle, with us, the only cost you will have is our cheap refills, no rental and no delivery. To buy your own mig gas bottle all you have to do is call or email us and we look after the rest. The first cost you pay includes the cost of the cylinder, and for a medium sized cylinder (the E size stands up to your waist) say the E size bottle this cost is $460. Thereafter, whenever you need more gas, call, text or email us and we deliver a refill (replacement) bottle full of gas and collect the empty one, and this refill cost for the E size is $160 (nothing more to pay). Prices for all Argon gas bottles (plus GST): Bottle Size First New Cost Refill Cost C bottle - (0.6m3) $220 $75 D bottle - (1.7m3) $360 $110 E bottle - (4m3) $460 $160 G bottle - (8.7m3) $560 $180 Depending on the number of welding gas bottles you purchase and how often you refill them, are the two key items that will help determine how much you can save. If you have any questions please feel free to contact us. Email: simon@rentfreegas.com.au Phone: 0404 677 187 

Argon Gas Bottles & Regulators

Argon Gas Bottle Valves There are many different types of regulators out there with many different suppliers. So there can be confusion about the cylinders, the valves, and what connections and regulators are required. We hope the information below helps reduce the confusion. All Australian approved Argon cylinders have a Type 10 valve and all regulators purchased in Australia should also have a type 10 valve connection. The only difference, for Industrial high-pressure cylinders, is that around 10-12 years ago the valve on the top of the bottles was changed from being vertical (i.e. the open valve was facing the sky), to being horizontal (pointing to the side). This change was made for safety reasons, specifically preventing moisture getting inside the cylinders. So as long as your cylinder is Australian approved as all Rentfreegas and Speedgas cylinders are, then you are ok. Regulators Regulators are used to control the flow of gas from the Argon cylinder to your job or application. The argon regulator allows you to work at a safe, and lower pressure, by reducing the high pressure inside the cylinder to the desired working pressure for welding. Below is an example of one of our regulators that includes a ball valve flow metre, allowing you to set the gas flow to anywhere between 0-25L per minute.             Some of the other gases and there valve outlets are: Gas Valve Type Argon Type 10 Helium Type 10 Oxygen Type 10 Acetylene Type 20 CO2 Type 30 Nitrogen Type 50 Air Type 60 Note: High-pressure Nitrogen cylinders have a Type 51 outlet connection. Check with your gas supplier about what valve type your cylinder comes with.

CO2 Beer & Pub Gas Prices, Sydney.

Sydney Prices for CO2 Pub Gas including delivery.  Our recent announcement regarding delivery of CO2 for pubs and clubs seeking to reduce their overheads by owning their own beer gas and post mix cylinders was met with great excitement and many questions were raised in regards to pub gases and food grade gas systems. First and foremost is how much does it cost?  The table below shows delivered prices in Sydney for both first purchase which includes a cylinder to keep forever and the refill swap price which is just a swap over of your empty bottle for a full one.   Beer / Pub Gas Prices (Delivered in Sydney)  Bottle Capacity New Full Bottle Refill Swap C - 1.8kg $200+GST $64+GST D - 6kg $290+GST $78+GST F - 22kg $325+GST $87+GST G - 30kg $400+GST $110+GST How does it work? This system works by you owning your own bottles and stopping the rental costs. So you need to purchase a bottle (cylinder) from us or Speedgas, as are not permitted to fill the big gas companies gas cylinders (like BOC, ALA, Linde, Supagas). After you purchase a bottle it is delivered to you full of gas, and then when it is empty we come out to collect it, and exchange it for a full bottle. This swap system works well for cafes and smaller pubs in the inner city of Sydney, that may have limited access, less room for storage, or need specific delivery times. What if I already have a Cellamix bottle? That's great, you already have most of what is required, just get rid of the cellamix bottle and purchase one of our gas cylinders.  You can start saving almost immediately and gee do the savings start to add up fast. Our gas bottles are rent free because you own them outright so unlike the Cellamix bottles that keep you paying monthly rental, our system saves you the monthly rental. Isn't Cellamix a special food grade pub [...]
