How To Choose A Welding Power Supply

The process of choosing a welding power source is much like that of buying a car. It involves searching for a product that is efficient, powerful, easy to handle and, most importantly, suited to the customer’s particular needs. But with such a wide selection of power sources on the market, how do welders select the right one for them?

Welding power source types are defined by how they modulate electrical currents and what arc welding process is best supported by this modulation:

Direct Current (DC)

A DC power source is a flow of electrons in a single direction through a circuit. In welding, it creates a steadier arc and smoother output. It can be used to weld with a negative ground, or the flow of electrons can be reversed to flow toward a positive ground in reverse polarity.

Alternating Current (AC)

The AC power source is the bidirectional flow of electrons in which the polarity shifts a hundred or more times per second from a negative to a positive ground. Arcs tend to be less stable and welding is harder to control. However, AC welding can break apart oxide formation and allow for purer welding in some processes.

Pulsed Current

This is a form of DC welding in which the current goes from a high peak current to a lower background current at a frequency determined by the operator. This narrows the arc, allowing greater penetration while reducing the effect on surrounding materials. As a result, pulsed current welding is an excellent choice for welding thin metal or performing deep welds on thicker materials.

Pulsed Voltage and Heat

Pulsing GMAW power supplies focus on controlling pulsed voltage and heat applied to the consumable electrode. Controlling the pulsed voltage (heat) and wire feed speed allows greater control over how the wire melts and the rate of deposition. Adaptive pulse GMAW carefully monitors feedback and automatically compensates to keep the arc consistent despite variation by the welder and differences in height and joint location.

Before You Buy

One of the most important elements to consider when shopping for a new machine is the warranty and certification. Odds are, you will need good warranty and technical support during the life of your machine. Be sure to purchase a machine from a reputable company and brand.

In addition, purchasing a certified machine (CSA and ETL certified) ensures the machine meets UL safety standards, which are applicable in the U.S. and Canada (note: CE certified is not). Beware there are machines sold in the U.S. and Canada without these certifications, and uncertified products are not tested or verified by a third party.

Common Soldering Problems And How To Fix Them

Have you been struggling to make the most of your soldering projects? Or perhaps you are just looking to get started with soldering and want to ensure you’ve got the necessary skills and knowledge in place first to help. Whatever the case might be, today, we’re looking at some of the most common soldering problems you should know about to help you decide how to approach these (and how to fix the issues, accordingly). 5 Soldering Problems and How To Fix Them Soldering can be a somewhat daunting task, and with this in mind, it can be easy to fall into a few common traps. Nevertheless, there are several easy steps you can take to help ensure you solder correctly and without making a mistake, and below are just a few of the most common issues you should be aware of. #1 Disturbed Joints Disturbed joints can be among the more common issues when soldering. These occur when the components or materials being soldered are moved while the solder is setting, which can cause the surface of the solder to appear rough; the displaced solder may also prevent a proper bond or connection from forming. Luckily, this can be prevented by ensuring parts are held tight while the solder is setting, and if needed, such problems can be repaired by reheating and carefully moving the solder into place. #2 Solder Starving “Solder starving” is an issue that arises due to too little solder being applied to the components; as such, poor or weak connections are made. This might result in insufficient electrical contact and poor joint strength, also leading to stress cracks over time. In order to correct this issue, re-heating the joint and adding a small amount of additional solder can potentially help by creating stronger bonds, instead. #3 Cold Solder Joints It’s easy to make a mistake with temperature when soldering, and cold joints are often formed when the soldering iron simply isn’t at the right temperature to begin with. This can prevent the solder from melting or flowing efficiently, which can in turn lead to poor sold placement or amounts. In turn, this can often leave a rough or unfinished look, and the solder may not form a strong bond, impacting the final results of the soldering work. #4 Overheating Opposite to leaving the solder too cool, overheating can also be a major issue – often one of the more extreme problems one might face when soldering, in fact. In many cases, high temperatures can scorch or burn the components and materials, leaving a burnt residue behind that is known as flux. Fortunately, such issues can potentially be fixed carefully with an isopropyl alcohol solution; however, more serious burns may need to be carefully scraped off, which can cause damage in itself. #5 Solder Bridges As a final issue to keep in mind, applying too much solder in close proximity to another solder joint can lead to solder bridges. This can create an unintended connection, resulting in short-circuiting or even complete inoperability, depending on the nature of the part and the severity of the solder bridge. As such, taking care to prevent this is hugely important; if you do experience any solder bridges, these may need de-soldering and fresh solder.

How To Solder A Circuit Board Without Damaging Components

Soldering can be an incredibly effective technique to use – however, making sure that you have soldered carefully is hugely important. In line with this thought, today, we’re looking at some of the key tips you should be following to help avoid causing damage to your circuit boards while soldering; hopefully, this will allow you to find the optimal approach for your own circuit board soldering efforts. 4 Tips To Avoid Damaging Circuit Boards When Soldering There are a number of techniques to note when soldering delicate electronics, such as circuit boards. Indeed, it can often be easy to make mistakes when soldering; as such, knowing the potential issues may help avoid damaging the components you are attempting to solder. #1 Pick The Correct Soldering Iron It may seem obvious, but one of the most important factors to keep in mind when soldering to ensure you are using the correct soldering iron is crucial when it comes to delicate electronics. Typically, the best soldering irons are those with variable temperature settings, which allow you to adjust the temperature accordingly to avoid damaging the circuit board. Nevertheless, fixed temperature options can still be used; however, you should always make sure that your chosen iron is a suitable temperature for the project in question. #2 Invest in a Reworking Station If you do make a mistake, consider investing in a reworking station. Indeed, reworking stations are ideal for adjusting or removing solder; however, they should not be used to solder components together directly due to the lack of precision and control. #3 Use The Right Solder Material It’s not just the soldering iron that should be right for your project; choosing the right solder is another essential factor to consider as part of this. Indeed, different solders have different properties, which can potentially damage your materials. There are two main types of solder used in electronics: lead-based and non-lead-based solder. Lead-based solder offers a lower melting point and is generally easier to work with, but there are naturally potential health risks associated with these, and high temperature irons could cause excessive melting and damage. Alternatively, non-lead-based solder may have a slightly higher melting point, which can be easier to control; however, it is better for the environment and your health. Choosing the right solder can also influence the chance of accidentally damaging the board, so take care with this to select the most appropriate option. #4 Always Use Additional Supports Soldering can be an incredibly complex and intricate process; as such, making sure you have plenty of supports in place is crucial to keep things stable and steady. Support stands can help hold the circuit board in place while you solder, preventing wobbling and risk; this also helps to free up both hands, allowing you to focus more carefully on the task at hand. Some stands even come with a magnifier to help when working on very small or intricate electronics, which helps reduce the risk of making a mistake on your projects.

Soldering Station

What Is The Difference Between a Soldering Iron And A Rework Station?

Soldering is an incredibly valuable process, offering a wide variety of benefits that can help make it a useful tool. However, if you have been struggling to find the optimal tools for your needs, knowing about the different options can help; in accordance with this thought, today, we’re looking at solderion irons and reworking stations – and, critically, how these differ from one another. Soldering Irons and Reworking Stations: What You Should Know If you have been looking to begin soldering work, it’s highly important to start with the right tools. As part of this, we’ve outlined some of the key things you should know about soldering irons and reworking stations as follows to help. What Is A Soldering Iron? When soldering, arguably the most important tool is the soldering iron itself – in other words, the heating element that is used to melt solder. These devices work by heating a soldering tip to a high temperature, which can be used to melt solder into a molten state. In turn, this liquid solder is then allowed to gradually re-solidify, which forms a solid solder bridge as a result. Soldering provides a range of benefits and often proves particularly useful in electrical applications. However, the range of potential uses for solder can be incredibly versatile, with these materials able to lend themselves to a huge array of applications, such as plumbing and even glass, composite, and ceramic product production. Soldering irons are extremely accurate and precise, making them crucial for soldering projects. They are also used for intricate tasks and cost significantly less than a rework station, making them excellent options for occasional work needing a high standard of finish (without the investment required for a full reworking station). What Is A Rework Station? At this point, we’ve considered how soldering irons work – but what about rework stations? Well, whereas a soldering iron is designed to apply solder, rework stations instead allow you to manually alter and tweak existing solder. In turn, this makes it a crucial piece of equipment for businesses or projects needing a way to alter existing solder without damaging the components themselves. Finding the Right One For Your Needs Both soldering irons and reworking stations can be incredibly valuable, and this is well worth keeping in mind if you have been looking for a suitable device for your needs. In fact, if your business or project focuses on soldering, it may be worth considering both options, as they provide very different solutions and therefore can both lend themselves to your project. Indeed, you’ll need a soldering iron to accurately apply solder in the first place; however, if you subsequently need to remove, replace, or alter the solder for any reason, having a reworking station may prove useful. With this in mind, if you have been looking to get involved with more complex soldering projects, we strongly recommend considering both products to help. Luckily, we here at Gordak are some of the leading providers of soldering products, so contact us today at info@gordakelec.com to learn more and to see how these might work for you.
