What You Should Know About Soldering Irons
On the market, you will find a wide variety of welding machines with various functions and features. Choosing the most suitable tool can be a big challenge, especially if you don’t know the mechanism.
What is a Welder?
An electric welding machine, also known as an inverter welding machine, is an innovative welding machine. The main difference between it and traditional soldering iron models is how they convert voltage into heat. These teams have internal electronic circuits that help the operator control the amperage and voltage.
Whereas traditional equipment converts the current-voltage through an internal transformer or rectifier to obtain a regulated (but not adjustable) voltage similarly, a welder has an electronic system or chip that provides the voltage digitally, so it is flexible and stable without spikes.
What are the advantages of electric welding machines?
Due to their small size and digital manufacturing, inverter welding machines have certain advantages over conventional welding machines. Most importantly, you should pay attention to optimizing voltage and power consumption due to the integrated board. Below is a list of the main advantages:
- They are smaller devices because they do not need to contain transformers or regulators.
- They are smaller and lighter, fully functional, and easy to transport.
- They are versatile multifunctional devices, as they offer the possibility of welding with TIG, MIG/MAG, or MMA without changing the machine.
- They feature a wide range of components and can precision welding using excellent electrodes.
- Reduce power consumption.
- They have a stable arc that translates into higher-quality welds. The electrodes do not stick, and the solder joints are more precise.
- The most reasonable price.
- Very advanced and easy to use equipment, even for those who have never soldered.
What are the parts of the welding machine?
While electric welders do require very little maintenance, it doesn’t hurt to know how the different parts of the equipment work. That way, you’ll be ready when you have to clean or disassemble the machine for maintenance. The following is a list of its main components and parts:
- Welding machine. It is the central and most important part. It is a group of elements that generate the energy required for welding. These include generators and digital boards that convert and adjust voltages.
- Ground or neutral. This wire is connected to the part where the electrodes are located.
- Electrode cable. This is the wire coming out of the wind towards the workpiece.
- Electrodes or electrodes. It is the rod that performs the welding.
- Power cable. The electrical connection to the machine allows the welding machine to work.
- Ampere regulator. It is used to regulate the required amperage. This will depend on the needs and characteristics of each job.
- High and low voltage switch. The button enables voltage regulation and can graduate as needed.
- Ground cable and electrode connection terminal. It is a cable that connects the winding to the part.
- Of course. This part is used to hold the electrodes, which allows for safer welding.
What are the advantages of electric welding?
When buying an electric welding machine, you can ask yourself precisely what advantages electric welding has over other traditional welding. First of all, electric welding is a straightforward process, and unlike other methods, it does not require special preparation and specific skills.
Electric welding is easy to learn and provides a robust process. This type of welding can absorb considerable tolerances, such as excess gas, dirt, or toxic atmosphere from the elements to be joined. Here are some advantages of this type of welding:
- A more aesthetically pleasing finish.
- Higher precision.
- Affordable equipment is easy to buy and comes with many parts and accessories.
- You can choose between small and large units depending on the purpose and the needs of the job to be performed.
- Equipment transportation is more convenient.
- High-speed welding on thin sheets.
- It can work both indoors and outdoors.
- Strong welding, good elasticity, and corrosion resistance.
How much power does the welding machine consume?
The consumption of electric welding machines will vary according to certain aspects. One of them is the strength you will be working with; the more durable the material needs more strength. The higher the current you run, typically 30 to 160 amps, the more power you need to do the job.
Another important aspect is usage time since spot welding is different from long-term welding. Regardless, you need to know that the device has its consumption peaks while soldering and doesn’t deplete when not used.
Can I use an electric welder to weld aluminum?
One of the main advantages of inverter welders is that you can use them to work on any metal, including aluminum. However, due to the properties of this metal, the welding process will be a bit more complicated than other less ductile metals.
Therefore, aluminum welding is only recommended for those with extensive experience in this work and always uses specific electrodes for welding aluminum. Otherwise, the desired results will not be achieved.
Can I repair my welder at home?
Since it is a complex device that works with high voltage, maintenance of an inverter welding machine is a task that should be reserved for professionals. Yes, some minor maintenance tasks can be done at home, like changing fuses or checking windings.
The fuse is on the back of the device in a circular socket you must unscrew. Once opened, replace the fuse with another one with the same characteristics and proceed to unscrew the bracket to leave it in place. As for the windings, you need to replace the damaged cable with a new one.
What are the best soldering iron brands?
When buying a welding machine, choosing a quality model at a reasonable price is essential. As with any product with these characteristics, branding will affect the quality of materials and finishes. To give you an idea, the best brands of soldering irons are Einhell, Stanley, and Royal Power.
Einhell and Stanley are two of the most recognized tool brands in the world. Stanley manufactures hand and power equipment, while Einhell specializes in power tools. Both are great options. On the other hand, Royal Power specializes in photovoltaic converters and welders, which is why its products are the best on the market.
What must safety regulations be observed when using electric welding machines?
The principal risks of using electric welding machines depend on using electrical current, the risk of burns or fire, and explosion. Direct electrical contact may occur in power circuits due to insufficient insulation. There may also be indirect risks if we are exposed to cases.
Another great danger comes from the eyes, either from a projection or from burns. This may be due to particle projection from the arc and the welded parts. Working in explosive environments or containers containing flammable liquids may cause an explosion or fire.
Here are some tips and safety rules to follow when using a welder:
- Use an electrode holder. This must be balanced and secured to maintain proper contact.
- Cables for all components must be adequately insulated.
- The cable used to power the welding machine must be suitable, do not use unsuitable wires that may cause overheating.
- Protects circuit cables from incandescent lamps, fats, oils, and other flammable products.
- The enclosure of the welding machine must be connected to the relevant ground wire.
- When welding, shields must be used to protect personnel from UV and light radiation generated during welding.
- Welders must always use safety goggles or a welding mask, which must have quality certification for the type of welding performed.
- You should always wear long sleeves and thick clothing for welding.
- You should wear a leather apron, leggings, and high-top safety shoes, preferably insulated.
- Clothing used for welding must be made of corduroy or fireproof material.
What maintenance does the welding machine need?
Soldering irons require less care and attention than traditional models. However, there is some preventative care and some maintenance that can have an impact on the durability and quality of the job. Next, we’ll explain how to perform essential maintenance on your welder:
- As with other electronic devices, you should first read the user manual carefully. Follow all the steps listed before putting the welder into operation.
- Verify that the machine is connected to power and the voltage is correct. Incorrect voltage can cause the circuit to blow. Always keep the device in a safe place where nothing can fall on it.
- Check the wiring status. If the insulating jackets of any wires show signs of wear, they should be replaced.
- Keep flammable products out of the reach of welding.
- When you are done working, turn off and unplug the device. Keep the soldering iron in a dry environment.
- After each use, visually inspect components for overheating, loose connections, and clean fan blades.
- If you work in a dusty environment, clean your device after each use. Most importantly, it prevents dust from accumulating on the circuits and fan blades.
- Store the electrode in a dry, airtight container.
Now that you know everything you need to know about electric welding machines, it’s time to learn the criteria for a successful purchase. We’ll go into more detail on these factors below, and they will determine a good team and the perfect couple.
Depending on the electrode’s material and the weld’s size, more or less amperage is required. Around 80 amps and 2mm electrodes are usually sufficient for homework or small professional tasks. On the other hand, for more complex jobs, 180 amps and 4 or 5 mm electrodes are required.
In any case, the best thing you can do is choose a model that allows you to adjust the amperage for each job. Most welders have presets for the most common uses. As always, we advise you to choose a model slightly more than your needs.
In this case, the operator’s experience is another decisive factor in purchasing. For example, if you’ve never used a welder, we recommend you go for a small unit, about 100 amps. These are very cheap and easy to use and will help a lot as you get acquainted with them.
For more specialized work, or if you plan to solder in high volume, a team of 200 amps or more is best. If you have soldering experience, this device will allow you to make good-looking and corrosion-resistant wires, as these models have a TIG soldering option.
Welders have advanced technology that allows them to meet high demands in terms of heat and the voltages they support. A model with a powerful fan is a must, as the internal digital board and system overheat and require cooling.
Interestingly, it has a thermostat that allows you to monitor the temperature inside. There must be a fuse system capable of absorbing voltage peaks and a thermal protection system for the circuit. These systems must have +/- 10% voltage change protection.
As for materials, you should choose something that gives you a strong and durable structure. One of the elements to watch is the casing, preferably metal, not plastic, as they can melt due to the heat generated in the motor and voltage converter.
Welder cables and hoses must also be made of the correct material. In this case, they must provide adequate insulation and protection. Usually, thick rubber is used to insulate hoses to give us better current protection.
One of the main advantages of electric welders is just their size and the portability they offer us. The device has to be lightweight and easy to move, especially in the case of a less powerful device you’ll be carrying from place to place, and shouldn’t weigh more than five kilograms.
Likewise, if you want to do small jobs in complex places, it’s best to have a lightweight device that can be moved around comfortably. The lighter the weight, the better. Inverter welders rarely weigh more than 6kg, so you should be able to find one that suits your needs quickly.
The welder should have some accessories to make welding easier. Although uncommon, some devices have some aspects of protection, such as leather gloves or welding masks. These items are necessary for the job, so having them early is probably best.
On the other hand, always check if they have some electrodes. You won’t be able to work without them, so pay attention to this element. It’s even better if your welder has several electrodes of different sizes. Some models offer replacement hoses, while others are sold without any accessories.
Welders have arrived to retire heavy conventional equipment. Every day, more and more professionals and DIYers have one of these powerful devices at home. These machines offer huge advantages, making welding affordable for everyone, even beginners.
All in all, if you are looking for a versatile welding device with a quality welding arc, no voltage spikes, excellent working capacity, the ability to operate on different materials and situations, and good value for money, a welding machine is your best ally.
