A metal inert gas (MIG) welder is a type of welding machine that uses a continuous electrode wire running through a welding gun to form welds on metallic pieces.
MIG welders use inert gases to prevent contamination of the welding process, which may result in sub-par or inconsistent welds.
When choosing a beginner MIG welder you’ll be looking at factors such as voltage, amperage, duty cycles, and weight of the tool.
Dive into our review of top 6 MIG welders for beginners and buying guide to help you choose the best model to help kick-start your welding venture.
What to Check Before Buying Best MIG Welders for Beginner?
1. Power
The power input of your MIG welder will be measured in voltage. Some welders come with dual-voltage power outputs of 115 volts and 230 volts, for instance.
Such welders are great if you want to vary power between low and high to achieve specific welds on metals.
Single-voltage MIG welders are great for light-duty welding because of their constant voltage.
2. Duty Cycle
The duty cycle is a specification used in welding, which defines the duration, within a 10-minute period, within which a welder can produce a specified welding current steadily.
If, for example, your welder has a duty cycle of 20% at 90 amps, this means it can run steadily for 2 minutes at that current, but after that, it needs to “rest” for the next 8 minutes before resuming welding.
Welders with higher duty cycles will weld longer at specific amps, hence their suitability for intensive welding projects.
3. Wire Speed
The wire speed is the rate at which the welding gun produces the welding wire that will be used for welding. It is measured in inches per minute (IPM) and also regulates amperage.
The wire speed of your MIG welder will increase as amperage increases. The reverse is also the same. Hence, if you set the peak amperage of your MIG welder is 120 amps, wire speed will be fastest at this setting.
Fast wire speed means more amperage and consequently, more heat, so less penetration, and excessive melt-through.
4. Material
When looking at material, we consider the material of the metals being welder, or the welding guide wire’s material. Most wires are flux-cored and made of carbon steel, stainless still or aluminum electrodes.
They are preferred for their welding efficiency when combined with the ideal inert gases.
The material you are welding on also matters when choosing a MIG welder. Most beginner models will handle mild steel of up to 3/8-inch in size.
Other common materials welded using beginner MIGs magnesium alloys, titanium, carbon steel, and stainless steel.
5. Thermal Overload Protection
Thermal overload protection is a handy feature included in MIG welders to prevent them from damage that may be caused by overheating.
Sometimes you may exceed the recommended duty cycle of your welder and it may get hot to the point of malfunctioning.
Thermal overload protection is a mechanism that will prevent such an outcome. Hence, you may benefit a great deal from buying a welder with the feature.
6. Easy to Use
For beginner welders, a MIG welding machine should be as easy to use as possible to make the setup and operation process fast and simple.
Most MIG welders require minimal assembly and are further made easy to use by including comprehensive user guides.
Some manufacturers include guide charts for with a voltage and amperage combination for different welding conditions.
7. Portability
The portability of your MIG welder will be determined mostly by its weight. Some models we reviewed were as heavy as 87 pounds, which makes portability difficult.
However, there are lighter models weighing about 20 pounds, making them significantly lighter and easy to transport from one point to another.
Some MIG welders have handles to provide gripping mechanisms that may improve portability.
