MIG Welding

Do Safety Regulations Regarding MIG Welders Make a Difference?

19 Apr , 2016  

Gas Metal Arc Welding, more commonly known as GMAW or MIG welding, is the process by which metals are welded by using an electric arc to heat and fuse the two pieces of metal together. MIG welders are very common and are used for industrial welding most of the time. Welding is an inherently risky job, and the welding workshops and companies in Australia have to follow strict safety regulations stipulated by Safe Work Australia. More…

Basic Guidelines for Getting the Best AC/DC TIG Welders in Australia

19 Apr , 2016  

TIG or Gas Tungsten Arc Welding is the preferred form of welding used by professionals today. TIG welding results have a good finish and high strength. While it does require some skill to operate, it is only because the filler metal is fed using the free hand. For welds that do not require a filler metal, TIG is as easy as any other form of high-temperature welding. More…

Tips on How to Hire the Best TIG Welders in Perth

23 Feb , 2016  

Gas Tungsten Arc Welding (GTAW), commonly known as Tungsten Inert Gas (TIG) welding is the preferred choice of many professional welders and hobbyists. The process grants the operator greater control over the weld but also requires a high degree of hand-eye coordination compared to other welding methods. TIG welding provides the most precise and controllable form of welding, resulting in stronger and higher quality welds.

Things You Need To Know Before Hiring MMA Welders in Australia

22 Feb , 2016  

Manual Metal Arc (MMA) welding is the most flexible and one of the most widely used arc welding process. It involves striking an arc between a covered metal electrode and a workpiece. The heat of the arc melts the parent metal and electrode, mixing together on cooling to form a continuous solid mass. The central metal electrode or core wire acts as a consumable, providing the filler metal for the weld. MMA welding can be used to join most steels like stainless steel and cast iron and many non-ferrous materials. It is the preferred method to weld mild and high-strength carbon steels.


Disposable Welding Gas

Welding Gas: Hire or Buy Disposable Welding Gas Bottles?

4 Jan , 2016  

Need a welding shielding gas for your MIG or TIG welder?

The question plaguing welders across Australia is whether it’s better to hire a welding gas cylinder or buy a disposable welding gas cylinder.

Here we reveal three reasons why buying your own is the smart choice, especially for the hobbyist, and DIY welder who will not be welding on a daily basis. Gas suppliers have been holding welders ransom for years, tying them into a hire system that makes them pay hundreds of dollars a year for a welding gas bottle they don’t even own. Let’s face it, if you’re only using your welder every now and again, the gas bottle rental system is pretty tough on the wallet.

However, professionals and hobby welders alike are now realising that this is not their only option. In fact, there are some real benefits to be had if you buy your own welding gas cylinders – whether you choose a smaller disposable cylinder or a large refillable cylinder. Whether you’re looking to weld with a CO2-Argon blend, Pure argon shielding gas, or pure CO2, Disposable welding gas bottles are becoming the go-to option.

Here’s why:


Renting argon gas and cylinders every time you need to weld will quickly add up. But buying your own cylinders gives you more bang for your buck. Plus there’s no need for deposits, ongoing rental charges and gas contracts. If you don’t need a large volume of gas, buying your own cylinder means you can simply pay for the welding gas you use, when you use it. To illustrate the point, a 2.2L disposable Gas bottle like this one by Bossgas will set you back $69.00+freight. You can also purchase the suited regulators for about $30, which a one-off purchase. Depending on your project there is enough gas in one of these bottles for several hours of welding. For some welders that’s could be enough for six months, or even one year’s worth of welding. Why would you hire a refillable bottle if this was the case?











Welders now have the choice of purchasing Disposable Welding Gas Bottles like these from BossGas

More Convenient

With your own disposable welding gas bottles, you always have the tools ready to do the job. They are suitable for most home TIG and MIG welding machines, when you don’t need a large volume of gas handy all the time. Once you’re done, you simply put it away until the next time. Easy.

More Portable

If you are only using your welder occasionally or are using it outdoors, smaller disposable welding gas bottles are small and lightweight. You can easily move them around and stow them away neatly when the job’s done.








HEAVY IN TWO WAYS: Reillable hired gas cylinders are not only heavy on the wallet, they can be heavy and inconvenient to move around

Which gas?

Before you go out and buy your own welding gas, you need to work out which gas is best for your job. For most shielding gas applications, argon is the principal gas used thanks to its high density and total inertness. This allows a welding arc to be easily formed without reacting with the metal components being welded. Depending on the application, argon may be mixed with other gases such as carbon dioxide (CO2) in small amounts. This gives different qualities to the gas to suit the welding job at hand. We always recommend you speak to a professional and do your research to work out exactly which gas you need before you buy. at eWelders we sell Argon Disposable Welding Gas Bottles, Argon-CO2 Disposable Welding Gas BOttles, and CO2 Disposable Welding Gas bottles. We are here to talk to you should you require advice on which gas best suits your application. Owning your own welding gas cylinder makes sense – both in terms of dollars and time saved.

MIG Welding

Beginners Guide to MIG Welding – Part 1

31 Dec , 2015  

Word on the street is that MIG is one of the easiest processes to learn!

The buzz is right in our opinion. MIG welding is an easy process to master. Get you parameters such as amperage and wire speed right, select the correct consumables and all you really have to it control your torch to lay a nice bead.

Following these steps, most people can learn to run good beads with MIG in a few hours. But there’s more to great MIG welding than just running beads, isn’t there? Well, this blog series won’t focus on end goal, we’ll talk your through the process. It’s a bit like the cliche every sporting coach pulls out every week in their press conference – “We’re focussing on the process”.

In the first blog of our series, we’ll focus on how to get everything set up and ready to go with your MIG welder. Preparation is key people!


A MIG welder is made up of a few different parts and its important to at least know the basics of your machine. Otherwise, it’s a bit like getting in a car and having no idea what does what – Sadly, we’ve seen a few examples of this!-

The Welder: Contains a spool of wire and a series of rollers that push the wire out to the MIG Torch. From time to time, the wire feed might jam up. Don’t panic is this happens, but you do need to know how to fix the isse. Open up you machine and check inside to sort it out. The spool of wire should be held on with a tension nut, tight enough to keep the spool from unraveling, but not so tight the rollers can’t pull the wire from the spool.

The Gas Tank: If you are using a shielding gas with your MIG welder, there will be a gas tank behind the MIG. The gas will either be 100% Argon or a mix of Argon and CO2, which will shield the weld as it forms.

The MIG Torch: This is the business end of the welder. The torch comprises a trigger to control the wire feed and flow of electricity. At the end of the gun is a tip, which will vary in size to fit whatever diameter wire you are welding with. Tips are a consumable item and can cheaply be replaced.

The Ground Clamp: The ground clamp completes the circuit between the welder, the welding gun and the project. You only need one clamp from the welder attached to your piece to weld, or onto a metal welding table. Make sure it is making good contact.

KNOW YOUR TOOLS: This video about the Cigweld Weldskill MIG Series takes you through a typical set-up procedure for a MIG welder



MIG welding is a safe form of welding, so long as you follow these steps to protect yourself and your welder.

Wear a welding mask: Any form of arc welding produces an extremely bright light, so you need to protect your eyes. Make sure where a Australian Standard approved aut-darkening welding helmet. The auto-darkening feature will kick in as soon as your arc starts and will darken the visor on your helmet far quicker than you can blink, ensuring you will not suffer any damage to your eyes. Failure to properly protect your eyes can result in welder’s flash, which is not a good thing and can result in permanent eye damage. Ensure your helmet has a minimum shade rating of 11 when MIG welding. You may need to think about protecting others too. Ensure others in the room are wearing eye protection before you MIG weld, or consider purchasing welding curtains to contain the light. As with helmets, ensure your curtains are Australian safety standard approved.

Wear gloves and leathers: You need to protect yourself from molten metal splattering off of your work. Wear whatever gloves you feel comfortable with, as well as leathers to protect your skin from the heat. If not leathers, wear clothing made from cotton as this won’t burn or melt.
Wear boots: Do not wear open toed shoes or synthetic shoes – boots are the way to go.

Well ventilated area: Welding produces fumes, which you shouldn’t breathe in if you can help it. Wear a mask if it’s going to be a long job. Professional welders should consider a fume extraction system

Fire safety: Keep a tidy area for welding so you don’t risk fire from the molten metal and grinding sparks. Always keep a CO2 fire extinguisher in the workshop just in case.


LAYING BEADS: It’s important to safely clothe yourself and set up your area before you begin MIG welding.



Next, it’s time to set up your welder and the piece you’ll be working on.

The Welder: Make sure the valve to the shielding gas is open and flowing through the regulator at the correct level. Turn the welder on, with the grounding clamp attached to your welding table or directly to the piece of metal. Then make sure you have the proper wire speed and power setting.

The Metal: For the best results, take a couple of minutes to clean your metal and grind down any edges being joined.

With everything set up, safely, you’re ready to weld. Stay tuned for part 2 where we’ll take you through the welding process step by step. Inspired to buy a MIG welder? Check out our full range at eWelders.com.au.

Plasma Cutters

4 Essential things consider when chosing a Plasma Cutter

28 Dec , 2015  

So you’re thinking of buying a Plasma Cutter? Good choice. But it’s not one size fit all, so here are four essential things to think about before you buy.

Fabricators, contractors, artists and DIY weekend warriors who have experienced the benefits of plasma cutting can never go back. It cuts faster, without the need for a pre-heat cycle. It can cut any metal that conducts electricity. A plasma cutter can be portable around the job site. And it’s relatively simple to use.

The only challenge comes long before you begin cutting – you need to select the right plasma cutter for the job.

First, let’s look at how a plasma cutter works. The plasma cutter uses an inert gas blown out of a nozzle at high speeds and, at the same time, an electrical arc is applied to the gas, turning the gas into plasma. This super-hot torch is hot enough to cut through metal quickly and easily. It’s that simple.


So how do you choose the right plasma cutter for the job?

1. Duty Cycle

The first thing you need to think about is how many hours the plasma cutter will be used for. This is the duty cycle, and you’ll find it listed in the product or owner’s manual of the plasma cutter. If it’s going to get frequent but not continuous use, look at the maximum cutting ability of the machine. If it’s only going to be used now and again, choose according to the average thickness of the items you plan to cut. (You should find this listed in the specs).

As a rule of thumb, you’ll find the plasma cutter with a higher amperage output has a great duty cycle at lower amperages.

2. Portability

This feature is only important if you are planning on moving the cutter to the material that is to be cut. If the plasma cutter is going to have a permanent home on one place, you don’t need to worry about whether it’s easy to move and transport. The good news is today most plasma cutters can be carried by a handle and are relatively compact.

3. Electrical Outlets

Don’t underestimate the importance of electrical outlet when choosing your new plasma cutter. The majority of plasma cutters need a great deal of power to work at their best. The power outlet must be able to support the minimum number of amps required by the plasma cutter. As a guide most single-phase 40amp plasma cutters require a 15amp plug.

Also, if there are other tools plugged into the same circuit, they will draw on the plasma cutter’s power source. Ideally, it’s best to have a circuit dedicated only to operating the plasma cutter.

4. Inverter

Some plasma cutters come with a built-in inverter. These are generally a bit more expensive, but on the upside, they provide additional portability you might be after. Inverter-based plasma cutters are housed in smaller designs, making them idea for mobile use.

One of the first things you’ll notice when browsing plasma cutters is that there’s a wide price range, from a few hundred dollars up into the thousands. Take the time to work out what you really want in your plasma cutter and you can never pay too much.

Aluminium TIG Welding

Beginners’ Guide: How to weld aluminium – Part Two (TIG)

17 Dec , 2015  

Need to weld aluminium but not sure where to start? You’re not the first. That’s why we’ve put together a 2-part blog series to help you get started.

In part 1, we focused on how to weld aluminium using the MIG welding process. Here, we tackle how to weld aluminium using TIG welding and reveal all those little secrets only the most pro welders know.


TIG Welding

TIG welding (tungsten inert gas) is known across the industry for producing the most beautiful welds. It is an extremely accurate process, capable of welding extremely thin metals together as well as very thick metals. How? Because TIG welding doesn’t heat up a large area of the work piece.

TIG welding works by using a torch with a solid tungsten electrode, Argon shielding gas, and a filler rod dipped into the weld puddle. A foot pedal controls the heat of the torch. Unlike many welding processes, TIG lets you weld steel, stainless steel, titanium, magnesium, cobalt alloys, copper alloys, and of course aluminum – the metal most often associated with TIG welding.

As with MIG welding, there are certain things to remember when TIG welding aluminium:

1.   You need TIG with AC/DC capability

TIG welder capable of welding in AC (alternating Current) as well as DC (Dirtect Current) cost more than machine that only provide DC welding. Our AC/DC range starts at $995, extrmely cheap compared to our competitors, but still more than DC TIG welders which start at $289.

However, if you’re planning to weld aluminium and you want to save yourself money by buying a DC TIG welder, forget it.

Why? Aluminium forms an oxide layer when exposed to air and this layer has a far higher melting temperature than the base metal itself – 1982C, compared to 648C.

If not removed properly, this oxide layer will inhibit proper weld fusion and affect its quality.

A TIG welder with an AC basically erases this oxide layer from the surface, so that the integrity of the weld is not compromised when the base metal melts.

2. Filler Rod

To weld aluminium, you will need an aluminium filler rod. This will bond the two pieces of metal. Be sure not to use dirty or rusty filler rods that will result in weaker welds.

3. Argon Gas

For TIG welding, you’ll need Argon gas for shielding. The most cost-effective solution is pure Argon, though 3% helium can be added to increase the stability of the arc. Some will even say that 50/50 argon/helium is worthwhile.

4. Clean, clean clean!

The thing about aluminium is that it forms a thin aluminium oxide coating on its exterior, kind of like a skin. The problem is this melts at a far higher temperature than aluminium. So before you can even begin welding, you have to clean off the aluminium oxide – even if it’s a brand new piece of aluminium. One way to do this is to use acetone on the joints, rinse the piece in water and let it dry fully. Then scrub the metal with a stiff brush. You also need to clean the filler rod, as a dirty filler rod can contaminate the weld. As previously mentioned, a welder with alternating current (AC) can also performcleaning of the oxide layer on aluminium.

5. Preheat is your friend

You’ll find that aluminium is easier to weld if the work is already much hotter than room temperature. If you weld thick pieces without preheating, you’ll get a weak and shallow bond. Heating the aluminium is as simple as putting it in the oven, or using a gas torch to the heat sink with the work clamped on – aim for about 176°C.

6. Practice run

Before you start welding have a few practice runs. There’s no need to light the torch for this if you’re trying to save on metal.

 The steps

  • Hold the torch similar to how you would hold a pencil and tilt it back very slightly at about 10-15 degree angle.
  • Hold the tip of the tungsten about 6mm from the metal. If you hold it much further than this the arc will spread too wide and the weld will become too difficult to control.
  • Practice running the torch along where you plan to weld trying to keep that 6mm gap between the tungsten and the metal. Make sure to practice with your gloves on so you get a feel for how it be once your arc is lit

The filler rod

  • Make sure to hold the filler rod at about 90 degrees to the torch tip. You will lead the the weld with the filler rod but you don’t want it to come into contact with the the torch tip because this will contaminate the weld

7. A few final bits of preparation!

Fit your aluminium sheets together as tightly as possible

TIG welders don’t like it when the metals are not fitted together nice and tightly prior to welding. It can result in a weak weld. Fill your sheets before you clamp them to avoid this.

Set your welder to the appropriate settings

  • Aim to set your amperage to about 1amp per 25mm in thickness of your aluminium. This may seem low but that is the nature of aluminium welding.
  • You can set the amperage slightly higher than your estimated need and then ease it back once under way.

8. Lets weld!

  • Use the diametre of your nozzle to gauge the distance between the nozzle and your tungsten electrode. If you’re using a 6mm nozzle, your tungsten should extend no further than 6mm from your nozzle.
  • Tap the electrode tip against the aluminium sheet and then pull it away about 3mm. At this point you can strike your arc.
  • Melt the work piece until you have a nice sized puddle, the size of this puddle needs to be consistent as you move along your weld.
  • As you move along the weld add just enough filler rod to fill the joint and create the the fusion. Continue this along the length of the weld.
  • Remember, the heat will increase as you weld so gradually lower the amperage.
  • Very slowly push the puddle created by the torch into the joint, adding filler as you go.


If you remember these factors when you TIG weld aluminium, you’ll get a much cleaner and better looking weld. Did you miss our blog on MIG welding aluminium? Check it out here.
