Buying Guide: How to Buy the Best Dual Voltage MIG Welder
MIG welding is getting popular among hobbyists and professionals for portability and power. We all want to buy an all-in-one solution for everything.
However, when buying a MIG welder, you must consider some points to determine which one will be best for your work.
The first thing you need to consider is the power of the welder. By power, we mean amperage. It can affect multiple other factors when you are welding. So it is important to choose the right one with the right range.
For a thin material like ⅛,” you will probably need 15-30 AMP power. On the other hand, thicker materials like ½,” bars need at least 140-AMP.
So, if your welder is lower than 120-AMP, it won’t work on heavy welding. Also, MIG welders with a minimum of the 75-AMP range are bad for thin materials.
For small to heavy-duty welding, you have to find the best welder that meets the sweet spot.
Wire Feed Speed
You have to control the wire feed speed because it directly affects amperage. So getting a welder with a wire feed speed controller is a must. Wire Feed Speed heavily impacts the welding quality.
Most of the time, you will find the wire speed chart on the welder body. At the same time, you have to maintain the perfect balance in material, amp, and wire feed speed for the best output.
If the feed speed is too low, the wire will disappear as soon as it touches the metals. It will result in an uneven weld, and its quality won’t be so good. Also, when feed speed is faster than necessary, it will create a spatter.
Performance is the top priority for any machine. However, both DIY and professional welders who move around for work must consider portability. Keep in mind that adding more features in a welder adds weight.
When it weighs more than 70 pounds, transporting it is an issue you need to handle. So choose one as light as possible without reducing the power and performance of welding, of course. So take all your considerations while buying a welder!
Voltage setting and wire feed speed need to be in a balance. So it would be best if you looked for a welder that will match the voltage range and the wire speed of your feed wire. Perfect voltage balance can give a better arc, but it can also melt the wire.
Low voltage and high wire speed will result in poor weld penetration. Even when you keep the voltage steady, lower wire feed speed will increase spatter and ugly welding.
A welding machine’s duty cycle is the % of time capable of safely at a specific amperage within a given time.
Let me explain with an example. A welder that has a 40 percent duty cycle in 70-AMP, which means it will work properly for 4 minutes in 70-AMP. The welder will heat up too much and won’t weld well. Then you will have to give it 6 minutes to cool off.
Changing Amperage to 140-AMP will cut down working time by 2 minutes. And increase resting time to 8 minutes.
Keeping the APM in the lower range can increase the flow of the duty cycle. If you have to work with thicker materials, the duty cycle should be one of the major concerns.
MIG Welders come in various voltage ranges. You can find 110/115/120V or even 220/230/240V MIG welders that work in different environments. 110V won’t handle 220V, and 240 won’t even work in 110V input.
Dual voltage MIG welders give you the flexibility to work on both conditions. Yet you need to check if the welder is actually in the 110v to 220v range.
Because a dual voltage can be in 110v to 170v or even from 200V to 400V range, which won’t help you, get the one that fits your input range.
Output power depends on various other elements, excluding the welder itself. And you have to understand what you are looking for from the welding materials. Stainless steel needs 10% less power, and aluminum needs 25% more.
The feed wire diameter also varies the output amp. The simple method to understand is thinner diameter generates less and thicker generates more output power. Usually, you will find the output power chart list on the welder’s body.
How Dual Voltage MIG Welder Works
MIG welding is a process to weld metal. MIG stands for Metal-Insulator Gas which lets you achieve welding without using an arc or flame.
The MIG welder uses this concept by converting electricity into plasma that permits it to be used on aluminum, stainless steel, and other similar metals. They do not require heating or melting to continue fabrication simply by providing energy supply instead of relying on fire flames. This gas is commonly a mixture of argon and regular oxygen (usually 2:1 ratio).
The primary mechanism of a dual voltage MIG welder is pretty straightforward. It converts the AC into DC to function correctly. Also, you don’t have to worry about the input current because the machine will adjust the setting.
Let me make it simple for you. If you have a 110V to 220V Dual Voltage MIG Welder, no matter if your input is 110V or 220V, it will operate on the output you want. When working in a home electricity environment, it will provide 110V power. And when you have 220V or up industrial input, it will work on that equally well.
How to Maintain Your Dual Voltage MIG Welder?
Whether you do welding for a living or just for DIY hobbies, you must want your welder to last long. For that, taking care of the welder is a must. Although you don’t need to take care of the machine like a puppy, some cautious steps can make the life of your welder a little long.
Cover it when not using
Covering the machine with a heavy sheet makes sure it’s not getting dusty. Especially if your garage or stock room is dusty, you want to cover the welder to prevent dust and protect it from damage. You can also find a cover for your welder from the manufacturer or buy it separately.
Clean the drive rolls
One thing most people forget to do is always clean the drive roll after every use. The carbon erosion can damage your machine if not cleaned properly with a brush or just wiping it off gently through a cleaning solution you could buy for this purpose.
Also, make sure that no debris remains on the extruder nozzle. There are many troubleshooting ways, including using a piece of saran wrap stuck tightly over all threads at both ends before drawing and also trying to turn the belt off if it fails. Or you can blow air in the rolls.
Coat the Contact Tip
When using the MIG gun frequently, the contact tip can become contaminated. The spatter from the feed wire gets stuck in the contact tip resulting in porosity. Too much splatter can damage your MIG gun contact tip because it decreases the flow of shielding gas that protects the contact tip. To avoid this, you can use a nozzle dip coating that prevents spatter from sticking in the tip.
Check the main wire frequently
Before and After every use and check the main wire of the MIG gun. Spatters can burn the rubber cover and expose the copper wiring. And if you are not careful, you can get an electric shock, or any other accident can occur. Not just that, if the power cable loses energy due to a leak, it will also affect the welding efficiency. So take a good look for any damage and replace the cable if necessary.
What Is a MIG Welder Best Used for?
MIG welders can work on both thick and thin materials. But it works best in thinner materials and for beginner welders. It does lesser damage because of better control, and the electrode instead of the flame creates less heat.
It works on Carbon Metals, Aluminum, Magnesium, Copper, Nickel, and other alloys. And you can repair car parts, motorbikes, or any other thinner materials without damaging too much.
What are some welding tips for dual shield welding?
Everyone has their strategy for working. But when a newbie starts welding, sometimes it can be overwhelming. Therefore, here are some essential tips that you can follow as a beginner.
- Don’t go 100% argon. It is costly and weakens the welding performance.
- Use 75-25 or Argon-Carbon Dioxide mixture, which helps in the perfect welding
- Try drag welding in the backhand instead of moving forward.
- Drag welding is safe when welding horizontally.
- Use Side by Side welding when you are doing it Vertically.
- Two preferred methods to avoid undercut are upward V or Triangle series.
- Keep the gun 90° and pull angle maximum of 10° for best welding.
- You will need a dual shield or flux core arc welding in tight spaces or indoors, so make sure you have enough ventilation.
Are dual voltage welders any good?
Dual voltage welders are excellent in both performance and portability. You can get 2 outputs from 110V to 220V or 120V to 220V, and in both voltages, it works evenly. You can get 120V for small jobs and change to 220V when you need more power from the welder.
What size MIG welder do I need?
You need to understand some factors before getting the best size MIG welder for yourself. You have to determine the Power Output of your working station, Thickness of material, and type of materials. Additionally, your experience plays an important role as well.
For simple garage repair like fixing your motorbike’s broken parts, you don’t need to go with a big-sized welder. Also, looking at the feed wire and type of welding, you might have to go with a different power MIG Welder.
According to experts, a 0.30-inch feed wire is best for beginners working on a 40-140 Amp welder.
A small MIG welder around 70lbs is fine. Because going to a bigger size will need a wheeled cart to move around.
Can I use a step-down transformer to power a 220v welder on a 110v circuit?
You can’t use a step-down transformer because you will need a step-up transformer for doing that. Theoretically, using a 220V welder on a 110V current with a transformer is possible.
However, that can cause a severe heating issue with your transformer. Also, a 110V circuit can provide 15 – 20 amps, whereas you need at least 50 amps to run some welders.
