With the reputation that comes with the Lincoln brand, this is an impressively low-priced MIG welder that makes light work of smaller welding jobs. Portable and compact, the Lincoln Electric Handy MIG Welder is relatively easy to use and is a good option for the hobbyist or DIY’er who feels there is a welder-shaped hole in their lives.
The trade-off for its compact size is that it’s not as powerful as some other mid-priced models, meaning it has a metal thickness limit of 1/8th of an inch. There’s no gauge so you don’t know how much gas you have left at any one time, but a quick trip to the DIY shop to buy an add-on will remedy that. And for heavier, more prolonged jobs it has a tendency to get a bit hot and flustered. But for the price and the Lincoln welders label, this is a more than adequate MIG and flux core welder for small jobs and essential repairs.

Best MIG Welder Buying Guide & FAQ
Things to Consider When Buying a MIG Welder
While a MIG welder is considered the easiest to use for home projects, not all welding jobs are equal so before you put your money down, you need to go through a few checks to ensure you are buying the best MIG welder for you.
- What you need it for
A MIG welding machine for full-on industrial use is going to be different to the tool you’ll use at home for general DIY or maintenance. You need to consider your workspace, your power supply and the environment around you, before choosing the best welder that is fit for your particular needs. How often you plan to use your new MIG welder will also impact on the final model – and price tag – you want to opt for.
- Type of weld
The type of welding job you are planning should influence the MIG model you choose. Consider the materials you need welding, the thickness of the metal and the overall scale of the project – the thicker the metal, the more power you will need. You then need to be sure you can safely power a unit that needs a higher voltage.
- Its ‘duty cycle’
The duty cycle is how long a unit can weld for in one go so check the figures on the model spec to ensure it can run long enough when you are on the job. The cheaper the MIG welder, then it will typically have a shorter duty cycle, and may not be suited to welding thicker metals.
- Thermal protection
When the heat is on, you need to be sure your MIG welder not going to get too hot, especially on a longer job. Check the safety features that will protect you from a temperature overload. An internal cooling system should be a standard. Also look at built-in protection against short-circuiting at a crucial moment as you don’t want a sudden power surge to knock your weld off track.
- Size, portability and weight
Size really does matter, especially when it comes to your MIG! A beast of a machine could well turn your head but if you’re needing to take it off-site or will be carrying it around then a larger unit could well end up a bit of a burden. If you need it to be portable opt for a lighter model, although you may have to compromise on a little power for the convenience.

What Can You Weld With a Metal Inert Gas Welder?
The MIG welder is a versatile tool as you can use it to weld a wide range of metals, including aluminum, nickel, silicon bronze and other alloys as well as carbon and stainless steel.
Depending on the model you choose, you can also use a MIG welder on metals with different thicknesses, whether that is super-light aluminum or a thicker steel.
Types of Welders
There are four main types of welders, and each have their pros and cons when it comes to how and where you use them.
- MIG welding
Also known as Gas Metal Arc Welding, MIG is one of the easiest forms of welding to learn and comes in two forms – bare wire and flux core (or both). Bare wire requires a gas supply to shield your weld while flux core can be used outdoors as it is self-shielding and so doesn’t need a gas supply to work.
MIG uses a spool of wire fed through the ‘gun’ onto the metal to create an electric arc to weld the metal joint. On non-flux core models, a shielding gas is also used to protect the weld from any contamination. A wire feed welder is popular for DIY and amateur body workers as it is easier to use and less expensive than other forms of welding methods.
- Arc welding
Arc – or stick – welding is the most basic type of welder and is pretty old school. With a bit of practice, it’s easy to get to grips with and not as expensive as other welding methods. Stick welding uses a stick electrode welding rod, coated in compounds and metal powders. An electric current is then used to make an electric arc between the electrode and the metals to be joined.
- Gas welding
Gas welding uses oxy-acetylene gas to create a flame that is able to melt steel and certainly looks impressive. When mixed together in the right quantities within a hand-held torch, the oxygen and acetylene can reach a temperature of around 3,200 °C and can also be adjusted to meet the melting point of other metals, such as silver, copper and bronze. This method can be used to both weld and cut thicker metals.
- TIG welding
TIG welding is a two-hand job – with one hand you feed the filler rod, and in the other you hold the TIG torch. TIG stands for tungsten inert gas and the TIG electrode provides the current to the welding arc, with an inert gas cooling and protecting the weld puddle for a clean and accurate finish. TIG welding is mainly used for aluminum, steel, alloys and titanium and is a preferred method for when a high-quality weld finish is needed.
Maintaining Your MIG Welder Machine
Look after your MIG and it will look after you. A simple but regular maintenance routine will mean you get plenty of safe and effective use out of your MIG welder:
- Removing dirt and dust from your MIG welder will keep it in good working order. Use a blast of compressed air to quickly remove any debris from its mechanical parts and always use your MIG welding machine well away from any woodworking and its associated dust.
- Pay particular attention to key sections of the welder: clean the drive rolls and ensure the tension is adjusted correctly, check the gas line and clear out any obstructions to ensure adequate flow and check that the gas nozzle is plugged in correctly and doesn’t leak.
- Ensure your welder is well-greased by wiping the oil to redistribute after use, and layer on a new application of grease when and where needed.
- Replace key parts such as nozzles, drive rolls or the brushes inside the wire feeder when needed and if you plan for heavy use, consider putting your MIG welder in for a professional service once a year to keep it in great welding shape.
- Always cover your MIG welder when not in use, either in its own storage case or in a general toolbox that is large enough for it to fit.
Best MIG Welder FAQ:
Q: What is a Metal Inert Gas Welder?
A: Simply put, a MIG – or Metal Inert Gas - welder uses electricity to join metal pieces together and is one of the easiest types of welding to learn. It works by using an arc of electricity to create a short circuit between the welding wire and the metal. The heat produced - along with a non-reactive (or inert) shielding gas to protect the weld from any contamination – then enables the metals to cleanly mix together. The result is a weld pool that fuses the wire and the metal to create a join.
Q: How do I set up a Metal Inert Gas welder?
A: Before you get started, make sure you have the right safety gear – protective boots, full-length pants, safety jacket, gloves, helmet and safety glasses are the basics. And make sure the metal you plan to weld is secure and you’ve used a metal brush to clean down the surface and any rust or contaminates have been removed from the joint.
You need to set your MIG welder to the type of metal you want to weld, so always refer to your user manual as the metal and its thickness will impact on the machine setting, electrodes and gasses to be used. Always ensure you’re using the correct filler wire and gas combination. The other key settings to get right are the voltage, wire feed rate and gas flow.
The correct combination will ensure you get the right transfer and sufficient heat to penetrate the metal without burning a hole. A little initial experimentation will help you to get that final finesse right, and then you’ll be welding like a pro!
Q: Can any MIG welder use flux core wire?
A: A flux core provides a self-shielding alternative to gas to protect the electrode from being contaminated by air, so is a good option if you are welding outside where there are windy conditions.
It depends on the model as to whether your MIG welder can also use a flux core wire as most are designed to either use wire with a shielding gas, a self-shielding gas/flux core or both. The key is the polarity of the torch – which needs to be negative if you are to use a flux core wire. You will need to check the functions on your particular model of MIG welder to be sure it can be switched to electrode negative for it to be able to work with a flux core.
Q: What shielding gas is used for MIG welding?
A: The purpose of a shielding gas when welding is to protect the molten weld from oxygen, nitrogen and hydrogen in the air. When the weld pool interacts with these elements, it can cause problems such as pores in the weld or increased splatter. Shielding gases for MIG welders are either inert or active. The most commonly used inert gas is argon, which can be used for most metals including aluminum. An argon/carbon dioxide mix is also a common gas mix to use with a MIG welder as it has active properties and so increases penetration, although it is not effective with aluminum.
