- You can use these with so many different metals, hence, these are versatile.
- Produces a good quality weld
But before you go welder picking from one of the top rated MIG welder under 500, you should be clear on what you are looking for. Ask yourself the following questions, and these will take you one step ahead:
- What materials are you planning to work with?
- What is your skill level?
- Will you use it outdoors or inside your house?
- How long are you going to use it in one go?
Once you have thought along these lines, you will be better able to pick on the features that best suit your needs. We have summarized some of these features in this guide to give you a fair idea about these MIG welders.
The Basics - Power, Volts, and Amperage
When we are talking about MIG welders, it is not just about how powerful your tool is. The voltage and the amps are an important consideration. It is the combination of these three which makes a welder effective.
Picking on the voltage, you have a choice between 120V and 240V. The main constraint here is the price. Most of the welders under 500 are 120V. Also, welders with a high voltage are more suitable for DIY tasks around the house.
The required amperage depends on the thickness of the metal that you are working with. With 110/120V, you can expect an output of 140A. And this combination is powerful enough to weld a steel sheet with a thickness of a quarter inch. For thicker metals, you need a greater amp welder.
Also, some of these come with dual voltage settings. As a result, you get a wide range of output current and, hence, you can work with many metals.
The Duty Cycle – Your Uninterrupted Working Time
Duty cycle is a measurement of the time for which you can use the welder, without stopping. After this duration, it starts to get heated up, and you need to stop and let it cool
It is mentioned in percentage, and dividing this by 10 minutes tells you how long you can use the welder without stopping.
For instance, a 30% duty cycle indicates that you can use the machine for three minutes without interruption.
Those with a high amperage will have a shorter duty cycle. This is because a higher amp level means more heat and power is transferred and, hence, your tool will heat up in a short time.
Inbuilt Safety Features Are Essential
Since welders are all about running on power and heating up during the process, safety features are a key design component. It should be protected against overheating as well as power surges and an unexpected spike in the voltage.
You should also check if it comprises a guard in case a short circuit occurs. Some MIG welders are also fitted with fans for cooling them down quickly.
Do You Want It to Be Portable?
It depends on your usage situation. If you are planning to use it at home or in your workshop, then you do not have to worry much about its weight and size.
Conversely, if the nature of your tasks is such that you will have to carry it around, then the weight is a critical point to be considered. Not only should it be very heavy, but there are some models which include a carrying handle to make it more portable.
An innovation is the welders that work on the inverter technology. Mostly these are the small ones that are used at homes, for small scale tasks and are lightweight. You can move them around conveniently, and these perform well too.
Flux-Cored vs Gas Shield
A MIG welder can use either a gas shield or the flux wire. The former gives you better results in terms of the neatness and the quality of the weld, but it is more expensive. Also, gas shields cannot be used outdoors, as the wind blows away the gas.
Flux wire does not work well with thin metals, but costs less and can be used in open-air areas too.
Using a Spool Gun
These add precision to your welding tasks. Not only do they give you a better result, but they will save you time by preventing wires from tangling around the rolls.
Accessories Included in the Package
Almost all the MIG welders available come with some accessories which are essential for use when you are working with these. The important ones are:
- A gas cylinder - the type of gas can vary, depending on your welder. Usually, carbon dioxide and argon are preferred.
- To control the gas flow and monitor its levels in the cylinder, you would need a regulator.
- A torch or a flashlight is vital.
- A helmet, mask, and protective glasses are crucial to keep you safe from the sparks.
Choose the one which includes most of these instead of purchasing these separately.
Taking Care of Your Welder
A well-maintained welder will give you better results and stay with you for a long time, giving you a higher return on the money you invested in it. To keep it working for a long time, do the following:
- Keep it covered to protect it from dust.
- The drive rolls should be brushed and cleaned frequently.
- Spatter sticks on the tips every time you use the welder. If you don't clean it regularly, it would keep building up and hinder the flow of gas. Therefore, it is better to use a nozzle for covering the tip.
- Check the diffuser for any clogged spatter by removing the cone, and getting rid of all that is stuck inside.
