Top Features of the Best TIG Welders
Whether you are a novice or a professional, a TIG welder is a handy machine to have around the house or at work. For small fixes, repair jobs, and maintenance, a TIG welder can save you a lot of headaches and, in the long run, save you money, as it is fairly easy to nip the issues at the start before they escalate into a real problem. A TIG welder creates high-quality welds and is safe for home use. Professionals will also appreciate the fact that a TIG welder is a highly versatile machine, used in various applications to generate a high-quality, snag-free weld that is durable and beautiful.
TIG welding is somewhat a complex process as compared to other welding machines. It, however, results in beautiful welds. Noting that a TIG welder is a great tool, it is prudent to know what to look for when checking out various welding systems before rushing to the store. Here are tips on how to choose the best TIG welder for aluminum, steel, stainless steel, and other metals.
First, you should start by looking at the current type of the welder. Current type is related to the depth of penetration, deposition rate, welding speed, and quality of the weld.
Different metals require different current types for welding. In TIG (GTAW), both direct currents (DC) and alternating currents (AC) can be used. To weld a variety of metals, use a machine that offers both AC and DC currents. For self-oxidizing metals, such as aluminum or magnesium, you should go for AC current. It is also used only for metals that need shallow penetration. For almost everything else such as steel, stainless, or copper, you should go for DC current.
Keep in mind that the standard US home electricity runs on around 115 volts, which is great for a mid-size TIG welder. However, an advanced TIG welder has the option of switching between 115 volts and 230 volts, in case you need more power.
It is critically important to consider the amperage range when purchasing a new TIG welder. TIG machines usually incorporate low amperage. While this may seem like a drawback, but in reality, it helps in different welding jobs. Unlike thick bars or sections that need high amperage, for thin metals, low amperage is required.
For welding thin metals, a TIG welder that goes to as low as 5 amps would be a perfect choice. On the other hand, aluminum, for example, tends to require much more power and would require a TIG welder of at least 200 amps.
The wider the range, the more applications you can work on without the need for multiple machines. You want a machine that has the widest range at the best price. An amperage range of 5 to 250 amps gives you great flexibility and versatility.
The duty cycle of a welding machine is the amount of minutes you can weld at the machine’s maximum output (amps) without exceeding the temperature limits that would cause overheating or burning the component parts.
Here is an example, if the welder is rated at 40% duty cycle at 200 amps, this means you can weld for 4 minutes at 200 amps of power before having to rest for 6 minutes before proceeding. The lower the amperage you use, the longer the duty cycle/minutes be.
For welding hobbyists and new beginners, a duty cycle around 20% is more than enough in most cases. Duty cycles of about 40% or 60% are often sufficient for TIG applications in industry and construction. While professional industrial welders require a 100% duty cycle, due to the long weld time that they could lose while waiting for a welder to cool off.
If you intend to use the TIG welder in the same spot, this may not be a concern. But if you intend to move around according to your job, then look for a portable TIG welder. One that allows easy movement to different areas where applications are to be made. Smaller TIG welders, primary inverter-based, are relatively easy to use, thus offers lots of versatility as compared to larger TIG welders that have to be ferried with a cart.
A small TIG machine is convenient when dealing with small jobs that do not require a longer duty cycle. After considering the duty cycle and power output, portability is the next thing that welders should consider. For homes where a large scale machine is not required, opt for a small welding machine that can move with ease around when doing your welding jobs.
A durable foot pedal is a key accessory to simplify the process as it allows one to increase or decrease the welding amperage as required. Foot amperage controls are vital, especially if working with aluminum, which quickly heats up during the course of the weld and requires more amperage. As a result, a good foot pedal becomes critical if you want to yield good results with TIG welders.
The projects involved sometimes require one to stand in some awkward positions while the process itself requires two hands. A foot pedal is necessary as it allows you to free up your hands so you can focus completely on the weld and manage the amount of heat to avoid the weld puddle becoming too large.
A good foot pedal should slope at a moderate angle that is neither too high to cause fatigue nor too low to be unreachable. It should be highly responsive so that one can adjust the heat input easily with one foot.
TIG welding involves controlling the amount of heat applied to the base metal. Most of the latest TIG inverters produce a higher number of pulses per second as compared to older TIG welders. TIG pulsing is necessary when working on a difficult joint or on thin metal. It also is required where too much heat can end up causing rust, such as in stainless steel.
A higher pulse rate creates a stronger weld as the welder has more control over the weld puddle. Good pulsing technology creates strong, clean, and high-quality welds while saving time and materials; thus, it’s a good feature to have.
There are three ways to start an arc or arc ignition when TIG welding; scratch start, lift start, and high frequency start. The overall best option is high-frequency start. This method works without any touching of the tungsten to the metal or beads, which results in almost no contamination to the weld. A high-frequency start is only critically important for welding aluminum.
The arc is crucial for the welder, and there is no other way to control it than to have high-frequency settings. The higher the settings, the more efficient your welder is for high-quality applications.
You may benefit greatly from a machine that has simple controls making your work more comfortable and straightforward. TIG is a high-skill process, but that does not mean that the machine must be complicated to use. You want a user-friendly machine with easy-to-understand controls. To avoid accidentally bumping into controls while at work and wrecking a project, invest in a machine that has controls that snap securely into position. Although this is purely a matter of personal preference, it may make work easier for you if the small things don’t get in your way.
Deciding on a TIG is not based solely on the purchase price but on a host of other factors that determine its suitability and efficiency. It should meet your welding needs while delivering a seamless experience to ease your load when at work. Beyond the price, ensure you have a high-quality device that boasts of a good amperage range, great adaptability, and good controls.
What is TIG Welding?
There are numerous processes that welders use to join metals; TIG is one of them. Heat, the type of pressure, and the type of equipment differentiate each process from the other. GTAW or TIG is among the most popular welding processes. Not only does it create superior welds, but it also require high skills, guaranteeing stellar craftsmanship. You may also be interested in checking our MIG welder reviews.
What about TIG Welding History?
TIG welding has a long history that originates from a Hobart Heli-Arc machine. It gets its name from helium gas, which was used as a shield around the electric arc. The process was developed in the 1930s and used widely in World War II to create many aircraft parts. Before the welding technology was invented, welders would rely on welding aluminum and alloy steels with a torch, which was time-consuming, tiresome, and required lots of skill.
How do TIG Welders Work?
TIG stands for Tungsten Inert Gas, which refers to the activity of using an electrode to create a weld. Another name for it is GTAW, which stands for Gas Tungsten Arc Welding. This technique uses a non-consumable tungsten electrode fed through a welding torch to weld two metals together. A TIG welder employs a constant current supply to create an electric arc between the work-piece and the tungsten electrode, using heat to generate a weld.
The weld area is protected from external contamination of the atmosphere or environmental elements by using an inert shielding gas or a cover gas, which is either argon, helium, or a combination of both.
TIG welders can be used without any filler metal, but for some welds, you might need a filler material or a wire for reinforcement. At the point where the arc hits the base metal results in a molten weld pool where the filler metal is slowly fed by the other hand to melt further, creating a weld. The finished product in this process is a slag and sound free weld that has the same properties as the parent metal. Check out this article comparing different welding methods.
What Can TIG Weld?
This type of welding can be used for a wide range of metals rendering it more versatile than other processes, such as;
- Mild steel, stainless steel, and carbon steel
- Aluminum and alloys
- Copper and alloys
- Nickel and alloys
- Magnesium and alloys
- Titanium and alloys
What are TIG Welders Uses?
GTAW is a great solution to many manufacturing challenges and is utilized widely in parts that require a corrosion-resistant, sturdy weld that can stand the test of time.
Since the process grants the welder more control on thin sections of non-ferrous metals and stainless steel, it is best suited for small sections that require a slag-free weld.
Many industries utilize TIG welding for this reason. It is widely used in the construction of vessels, pipes, airplanes, and spacecraft. Car manufacturers use TIG welding because of its anti-corrosive properties. Auto body repair shops also employ the process as artists appreciate the high-quality welds during sculpture welding. Race car fabrication requires the use of TIG welders for chrome-moly steel and aluminum for sturdiness and an excellent finish.
GTAW can be performed manually, automatically, or by using a hybrid approach. TIG can be used to weld in any position standing, sitting, flat, or overhead position. Great welders can make a good career out of top industries such as aerospace, petroleum, and construction. You may also be interested to learn more about the top-rated plasma cutters.
What are the Types of TIG Welding?
There are many welding processes that professional welders may employ, but these two types stand out the most; orbital TIG welding and manual TIG welding. None is considered superior to the other, and the choice remains solely on the welder as both result in a superior quality weld if done the right way.
Orbital TIG welding is an easy process that allows for automation when required. It is clean, which makes it produce higher quality beads and welds than most welding processes. Manual welding is a more precise solution to difficult joints or areas of application. It allows for more accurate and refined results in cases where orbital welding is not possible.
TIG Welders Advantages
There are many advantages that a TIG welder offers. One of the top benefits is that it allows a welder maximum control.
- The welder has total control on the amperage and heat with high accuracy using their thumb or their foot.
- The process works great on thin materials as TIG welding uses low amperage.
- Amperage and heat control allow the welder to quickly switch from working on thin pieces of metals to larger ones rendering TIG welding a versatile process.
- Used on a number of metals, including stainless steel, aluminum, copper, and dissimilar metals. When done correctly, it results in a high-purity, top-quality weld compared to other welding processes.
- Can be used without a filler wire or metals. It uses a non-consumable electrode; the process can weld by fusion alone without the added fillers.
- There are no fluxes used, and a welder can create a low-profile weld bead that is clean, free of slag with minimal finishing required.
- TIG welders are quite desirable in projects that require detailed and minimal distortion for designs, curves, or any form of artistry on the base material.
- The TIG welder can perform in any position. The welder gets more control to get an accurate and beautiful weld.
- A TIG welder gives a solution to welding critical joints where highly precise welds are needed. Resulting in strong and clean beads.
- A clean welding process with a minimal amount of fumes, sparks, and spatters.
TIG Welders Disadvantages
One of the top disadvantages of TIG welding is that it takes a high level of skill and dexterity when compared to other types of welding.
- It is comparatively more complex and challenging to master.
- TIG welders will need both their hands and foot to perform their work, making it quite undesirable sometimes. Further, it requires a high level of focus and hand-eye coordination.
- GTAW can be performed on most metals, but some cannot be welded using this process, for example, metals of thickness over 5mm.
- Performed only on clean metals to maintain a high-quality weld, which ends up taking so much time and energy.
- Although it is known for producing one of the best welds, it has a low deposition rate, which translates to the fact that one cannot TIG weld things very quickly, making it slow and time-consuming.
- Low tolerance for contamination of the filler or the metal base.
- High initial coast, shielding gases used are also expensive. The process must also be done by a qualified technician resulting in higher labor costs. The overall costs may also increase in case of improper welding, contamination, unbalanced heating, or inclusions as products can become defective.
- Without destroying each component, it’s quite difficult to separate two items that have been welded using GTAW. It can be done but isn’t advisable as the items cannot be reused for any other application, and most welders discourage this process.
TIG welding is a complex and time-consuming process that requires the mastery of the skill for a high-quality weld. However, it is quite rewarding as the results of the process are admirable and precise if done correctly. Despite its challenges, TIG welding is one of the most efficient ways to join two metals.
