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.
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.
