Buying the Best TIG Welder For Your Needs
Now it’s time for us to look beyond some of the products on the market and look at specific advantages of TIG welding, important features and more. We hope that by combining this with our reviews, you’ll get a well-rounded perspective on TIG welders and which one best serves your purpose.
Firstly, let’s take a brief look at each of the 4 main welding processes in order to ensure that TIG welding is right for you:
- TIG Welding
Arguably the most difficult type of welding to learn, TIG welding is most often used to weld alloy steel, stainless steel, aluminum, magnesium and copper alloys. With it, a user can produce very precise welds of the highest quality once they have developed the necessary level of experience. The reason for this is that you’re given greater control over the weld with this particular process though keep in mind that the process is much slower. Finally, the weld beads produced by TIG welding can even look aesthetically pleasing.
- Precise, high-quality welds
- Great deal of control
- Difficult to learn
- Slow process
- MIG Welding
Of all the welding types, MIG welding is the easiest to learn. Welds produced are of high-strength. What’s more, there’s little need for cleaning because there’s no slag. While it can be used on thicker plate metals, MIG welding offers better control on thinner metals. Another advantage is that because it’s easy to do, high welding speeds are a real possibility. However, you are limited to the positions in which you can do MIG welding. Also, it’s not really suitable for the outdoors since the wind can interfere with the gases used. However, you will need to buy a great MIG welder to do proper MIG welding.
- No need for cleaning
- Easy to learn
- Allows for high-speed welding
- Limited positions
- Not suitable for outdoors
- Stick Welding
Stick welding is one of the most popular types of welding available, particularly when it comes to home workshop projects. One of the main reasons for this is that it’s the most economical option. It’s most effective when it comes to welding alloys and joints. What’s more, it can be done indoors or outdoors and wind and drafts don’t have a negative impact. Aside from working well on thicker materials, Stick welding can also be used on rusty or dirty metals. Unfortunately, it’s not the quickest of welding processes and cleaning is required.
- Fairly cheap
- Can be done indoors or outdoors
- Works well on rusty and dirty metals
- Quite a slow process
- Cleaning is required
- Flux-Cored Welding
Much like with Stick welding, Flux-Cored welding works well on rusty and dirty materials. It’s particularly effective outdoors, even in windy conditions. This makes it a particularly popular choice when it comes to construction sites. It’s a fairly portable option and, as such, can be used in various positions which can prove useful on certain projects. Caution is advised when using Flux-Cored welding indoors since it produces fumes and smoke. Also, it’s not the cheapest welding type due to the consumables.
- Works well on rusty and dirty materials
- Suitable for outdoor, windy conditions
- Can be used in different positions
- Produces fumes and smoke
- More expensive due to consumables
Top TIG Welder Features to Consider
Your budget may well define the amperage you can get in your TIG welder. After all, the more powerful a product, the more expensive it typically is. The wider the amperage of a TIG welder, the more metals it can weld. We recommend that you get the product with the most amperage that you can realistically afford because it will be able to do more jobs in the long-run. Some of the products listed above have 200 amp which is more than enough for most of your welding needs.
- AC and DC Welding
If you can find a product that is compatible with both AC and DC welding operations. The reason for this is that it’s hard to say which one you’ll need depending on the task. Generally, AC welding is best used with thin aluminum metals while DC welding works well with steel sheets.
- Duty Cycle
The duty cycle of a TIG welder refers to how much load it can handle over a specific time span. This time span is usually 10 minutes. If a machine goes beyond its capabilities, it will need to cool down before starting up again. For example, if a TIG welder has a 50% duty cycle, it can weld for 5 of 10 minutes before it needs to cool down. To give you an idea of what to look for, a duty cycle of 50-60% is quite reasonable. If you’re able to purchase a high-end machine then you can expect the duty cycle to be as high as 80-90%. The higher the duty cycle, the greater your productivity!
In some cases, portability may not be that important. This is especially the case when you’re working from your home workshop and simply don’t need to take your TIG welder elsewhere. But if you’re moving around from job to job, you’re probably going to want a unit with a handle. Thankfully, most TIG welding products come with a handle for easier transportation. When portability is a factor, you may want to look at more lightweight products. The problem with this is that such TIG welders tend to be less powerful unless you’re willing to pay good money for a top of the range unit.
- Heat Control
No matter the thickness of metal that you’re working with, heat control is another important thing to consider. The heat needs to be controlled otherwise it can damage metals, particularly thing metals such as aluminum and magnesium. This causes warp and burns which can obviously ruin a project. Therefore, it’s important to find a TIG welder that has a reliable heat control system to avoid such issues.
- Cooling System
Not only do you want heat to be controlled, you also want your TIG welding equipment to be cooled! A cooling fan (or similar) can stop your TIG welder from overheating which can prevent problems that will require you to start rummaging around for that warranty! TIG welders with good cooling systems tend to be a little more expensive but we think it’s worth paying a little bit more for some additional protection.
Top 10 TIG Welding Tips
Now that we have learned about the different types of welding and the various features to look for in TIG welders, let us finally provide you with our top 10 TIG welding tips!
- In order to prepare a joint for welding, you should take the time to clean it. Removing grease, oil, dirt, and paint reduces the chance of arc instability and contaminated welds.
- If your workpiece is in any way unstable, why not use a clamp? Doing so can provide much-needed stability for not only your own safety but your comfort as well.
- In order to avoid distractions and interruptions, keep all of your welding pieces close at hand, already cleaned. This will boost your productivity in a big way.
- When you’re learning how to TIG weld, opt for larger diameter rods. This will help since the bigger the rod, the easier it is to feed.
- If you’re welding aluminum, you may need to turn up the heat! Because different metals require different levels of heat, be sure to research in advance to find out the optimum temperature.
- The angle at which you direct your torch can have a big impact on the penetration you get when welding.
- You may need to change your tungsten depending on the material on which you’re working. Green is typically used for aluminum and red for steel.
- AC offers more cleaning properties which makes it better for aluminum. This helps it break through the oxide layer which DC cannot.
- If the tungsten tip touches the weld puddle then it has been contaminated. For this reason, you should take the time to re-grind your tungsten again.
- For your first project, stick to something simple. You could practice on old sheet metal until you become more confident in your welding abilities.
Choosing a TIG welder can be quite a complicated process. After all, there are so many products on the market from so many different brands. On the plus side, at least you know that there are TIG welders available to meet your budget. By exploring the pros and cons and the included features, you should be able to find a great product.
Our hope is that our reviews of TIG welders and buying guide save you some time and energy. With all of this information, it should be much easier for you to reach a decision and, with any luck, you’ll soon be TIG welding on all sorts of metal materials. Good luck!
