How to Choose the Best MIG Welder?

Investing in a new MIG welder is a great decision if you need a tool that can provide a quality finish that can be depended on. However, knowing how to choose from the options available can leave you feeling confused. Find out more about MIG welders (1) by checking out our advice below.

What Minimum and Maximum Amps Will You Need?

Before you can make a decision on amp-age, you will need to consider what you will be welding and how frequently you will be using your new welder. For welds with steel that is 5mm thick, you should look for a welder that offers max amps of around 150 – 180. However, if you are welding steel below 5mm then you can opt for a device under 150 amps. In terms of the minimum amps that you should buy, anything less than 30 amps won’t do a great job on steel that is more than 1mm.

Should I Get a Device with Constant Live Torch?

Picking a MIG welder that comes with a constant live torch should be avoided if at all possible. Unfortunately, many manufacturers leave out a contactor in their designs as a way of saving cash but this can lead to eye injuries that are painful and frustrating.

Choosing the Right Quality

Many consumers are keen to find the best value for any purchase that they make, especially when it comes to investing in an expensive new tool. Rather than letting price be the only deciding factor for your new MIG welder, think about quality too. The more you are willing to invest in your new MIG welder, the better the safety and quality of finish. However, if you are a hobby welder then don’t become blinded to the quality argument and purchase the most expensive model when there are many mid-range options that can offer what you need.

What are the 3 types of mig welders to choose for beginners?

Does Brand Matter?

There are many welding fans that will try to tell you that you should only ever buy a specific brand of MIG welder but this is not the case. There is a wide range of decent brands across Europe, China and South America. If you have heard of the brand and like the spec on offer then you can buy confidently. However, if the brand is new to you and the offer seems too good then it probably is!

Accessories You Need

Buying a MIG welder is the first step, but picking out the right accessories is also an important part of your purchase. You will need a torch and a gas regulator as well as a welding mask and other safety equipment. Take the time to find out exactly what you need so that you don’t end up frustrated and unable to use your new tool.

Choosing our favourite model was pretty difficult as there are lots of great options on the market. However the Unimig Viper 182 MIG & Stick Welder Kit really did stand out in terms of reliability, safety and ease of use, making it our best overall.

This kit not only offers you a Viper MIG welder but it also comes with a welding helmet, consumable starter kit and even a welding trolley to help keep your device clean, organised and off the floor. It also is made to take a spool gun and comes with a geared wire drive.

In terms of what it can do, you can look forward to welding steel, stainless steel, copper, cast iron and aluminium with this single-phase device. It also comes with a 2-year warranty, covering you for any issues that come to light when you start using it.

2. MetalTech Gas & Gasless MIG Welder (Best on a Budget)


If you need a MIG welder that is at the lower end of the price range then the MetalTech Gas & Gasless MIG Welder is a great choice! It is an 18 amp gas and gasless model that comes with a torch connector and has a number of great safety features that will help you get the best results every time.

The device is spool gun ready and it’s best used with 1kg and 5kg spools. It has variable controls and speed settings to work at your pace and comes with a 1-year warranty in case of any manufacturing issues. If you were looking for a good mig welder then this is the tool for you as MetalTech Gas & Gasless MIG Welder work really well.

There are a number of great inclusions with this MIG welder, including a Euro Torch connector, a 3M earth clamp lead, a 3M gas hose, gasless wire, solid wire, wire roller and more. It also comes with three different contact tips. Overall, you can be certain that you will be ready to weld when this machine arrives at your door.

If the first two suggestions don’t offer what you want then the Weldclass MIG/TIG/Stick Tradies Welding Kit is well worth taking a look at. It weighs in at just 9kgm making it both compact and seriously lightweight for a welder. 

It can provide up to 180 amps of output and comes with a heavy-duty torch for the toughest jobs. It also has an earth lead and LCD display making it safer and easier to use than other models. There’s no doubt that the stick and TIG welding options make it an attractive choice too.

This kit works to provide you with everything you need to get started including your welding helmet, gas and gasless wire, MIG pliers and a magnetic square. Well worth considering if you want to get a quality option for your welding needs.

That’s what makes it one of the best mig welders for beginners. If you find yourself fitting in this category then this might be the correct choice for you. But that doesn’t mean that it isn’t a great mig welder overall as well.

Last but not least is the Weldclass Gasless MIG Welder that packs some serious punch and comes with great features that you won’t always find on smaller machines. It gives 140 amps, comes with an LCD display and has been designed to make the controls as easy as possible to use.

You can weld up to 4mm cleanly and the machine is optimised to work with 0.8mm gasless wire, although you can choose to use 0.9mm wire too. The torch is included in the package and it also has a comfy shoulder strap to help you work for longer.  This 10 amp mig welder is going to work wonders for you and you’re going to thank yourself for getting such a  great option.  

The machine does come with a warranty, but it only lasts for 6 months, making it important that you give your device a full test run when it arrives to ensure that there are no manufacturing problems that need to be resolved.

Frequently Asked Questions About MIG Welders Australia

Ultimately, the main difference between buying a cheap MIG welder and a more expensive version is the ease of use. If you are new to welding or want the best finish then avoiding cheap options is the sensible choice. However, if you only need it for occasional use and aren’t too stressed about the neatness of your work then a cheaper model could work. Shop around to find the best spec for the price you can afford in order to make the best compromise.

The maintenance needs for a MIG welder differ from model to model but are generally straightforward. Some of the simplest ways to reduce issues include keeping it covered when you aren’t using it, hanging it up off the floor to avoid letting dust and debris in and performing regular inspections of the ground lead and cables to ensure that they are clean and safe. Doing these three jobs every time you use your MIG welder will help you prolong the life of the machine.
