What You Need To Know About Inverter Welder Before Choosing A New One?
Why inverter welder is different than conventional welder?
Inverter welders use electronic devices to coverts higher voltage to lower voltage without the help of a huge transformer.
A conventional welding machine uses a transformer to lower the voltage, the transformer is big and very much heavy. This also increases the size of conventional welders.
While inverter welders use electronic components to regulate the voltage; they first lower the voltage through electronic circuits, then there can be a small transformer.
The voltage is already regulated before entering the transformer which reduces the size of the transformer.
Consequently, you have a compact and lightweight welding machine. The output of common inverter welders is usually DC, but some welders can provide AC and DC both.
The internal circuit of the inverter welders is complex, but they are compact, lightweight, and much more efficient than conventional welders.
They are very easy to transport. The weight of them is around 8-30 lbs which is much less as compared to conventional welders.
The power consumption is also low, they save energy due to high efficiency. The efficiency can be around 80-90% which is not possible in conventional welders.
Moreover, you can also use most inverter welders with generators. These welders can easily regulate the impure power of generators.
Conventional transformer welders are mostly AC, while the inverter welders can be AC or DC. They have many options for electrodes, and the arc is more stable.
The duty cycle of these welders is also better. This is a new technology as compared to transformer welders, both of them have advantages and disadvantages. Inverter VS Transformer Welders What Is The Best For You.
What is IGBT Inverter Technology?
You might have heard a lot about this technology while buying an inverter welder. IGBT stands for Insulated Gate Bipolar Transistor. These are transistors with a very high switching frequency.
These are used to make in the making of inverter welders. There can be welders based on old MOSFET technology, but IGBT is the new and preferred.
This technology is complicated, but it provides a user-friendly welding machine with excellent efficiency.
The output of IGBT is much more reliable than MOSFET, they can handle power fluctuations; therefore, they are less likely to get damaged.
How To Select The Right Inverter Welder For your Job?
Inverter welders are not easy to purchase. If you are new, then you might not know about its features and functions. You may end up buying something useless.
There are many types of inverter welders in the market, but before buying anything, you need to know about them.
So, we are going to give you a proper idea that will help you get the best inverter welder.
Types of Welding Processes
The first thing is the type of welding process. You need to know what type of welding process you want. The common types are,
This is a type of Gas Metal Arc Welding. In this welding, a shielding gas is used that prevents any reaction of the object with the air. It uses a wire that is in the TIG torch.
When the user presses the trigger, the wire comes out. The arc is created between the base metal and wire, and the wire is melted.
This type of welding is not suitable for outdoor use. This is used for automobiles, plumbing, etc. It provides a fine weld with less spattering.
Flux Core Arc Welding
This type of welding is the same as MIG welding, but it does not require any shielding gas. The same torch can be used with it, and it uses a special wire called Flux-cored wire which can provide shielding. It is suitable for outdoor use.
TIG welding uses a non-consumable tungsten electrode. The arc is created between the electrode and the metal. Due to the high temperature, the base metal melts, and you can also use an optional filler. This also requires a shielding gas.
This type of welding uses a consumable flux-coated stick that works as an electrode. Due to arc, the electrode melts and joins the metals. The flux in the stick provides the shielding effect. These were the common types of welding, you can choose the desired one according to your work.
There is an adjustment knob in almost all inverter welding machines. This is used to adjust the current. You can easily adjust the current according to your needs.
The minimum and maximum value of the current depends on the machine you are using. For an accurate setting, there is a digital display in many machines.
Maximum Current and Duty-cycle
The maximum current is always mentioned on the welding machines. It tells the output current that the machine can deliver.
It tells you what kind of work you can do with it. The amperage can decide what base metal can be welded. Duty-cycle is an important factor when you are buying a welding machine for professional use.
The duty-cycles tell you the time up to which the machine can weld continuously. For example, if the duty-cycle is 60% at 200A, then it means you can drive 200A for 60% of the time. After that, you will have to wait for the 40% of the time to use the welder again.
Therefore, the duty cycle tells the continuous use of a welding machine. Let’s assume the time is 10 minutes, then you can use the machine at 200A for 6 minutes.
After that, you will have to wait for 4 minutes. If you are using the current less than 200A, then the machine can work for more than 6 minutes.
If the output current is very low, then you can use the machine continuously. While buying the machine, you should check these two things. The higher the value of duty-cycle and maximum current, the better it is.
Types of Metal that can be Welded
You need to know which kinds of metals the welding machine can weld. Some machines can weld ferrous metals, some are compatible with aluminum and some can weld a few metals only. Make sure to know the metals that can be welded.
There are some protection features with the welding machines. There can be protection for over-current, under-current, over-voltage, under-voltage, overload, etc. These protections will keep your welder safe from damages.
Whenever the electrode sticks to the base metal, the machine gets overload. It can also damage the machine.
Anti-sticking is a technology that refrains the machine to get overload. There is a device/circuit inside the machine that turns it off if the electrode sticks to the base metal.
This allows the easy removal of the electrode and prevents the machine from any damage due to overloading. This feature is present in new welding machines.
Size and Weight
You need to care about the size and weight of the welding machine. The weight of common welding machines is around 15-30 lbs.
There are welding machines of lesser and higher weights as well. But this range is perfect to carry. You can carry the welder with ease.
If you need a light welder for working at home or higher places, then you can find welder near to 10lbs or less. A lightweight welding machine is easy to carry.
You should check the operating voltage of the welder whether it is 120V or 240V. Some welding machines can work on both voltages. The machines that work on both voltages have different maximum current at the voltages. The maximum current at the higher voltage more than the maximum current at the lower voltage. For example, a welding machine has 200A at 240, then at 120V the current will not be 200A, it will be less.
The efficiency of the welding machine shows how much energy is converted and how much is lost. IGBT inverter welders have excellent efficiency. You can easily find an inverter welder with efficiency in the range of 85%-90%.
The warranty for most inverter welders is in the range of 1-3 years. Some welders also have a five-year warranty. The manufacturer can also provide a satisfaction money-back guarantee. If there is any satisfaction guarantee, then you can buy the thing with confidence.
