    Buyer’s Guide: Choosing the Best TIG Welder

    If you’re looking for a dependable, high-quality TIG welder, it’s crucial to do your homework before making a purchase decision. After all, it’s an investment you’ll use for years to come.

    If you’re confused by the variety of choices available to you when looking for a TIG welder, don’t worry. We have put together this buyer’s guide to help you choose the best TIG welder for your needs.

    Type of Input

    There are two common types of TIG welders: AC/DC and DC only. AC/DC welders can use both alternating current and direct current. So, you can work with a wide range of metals.

    Direct current electrode positive (DCEP) is the most common type of TIG welding. Electricity flows from the metal to the tungsten electrode. This type of welding works on metals such as brass, magnesium, aluminum, and copper.

    The other one is a direct current electrode negative (DCEN). Electricity flows from the electrode to the metal. You need to reverse the polarity for this type of input. Otherwise, it might not work at all.

    It’s best for jobs that need small amounts of heat such as carbon steel, nickel alloys, and stainless steel.

    Alternating current (AC) flows back and forth between positive and negative outputs. It works with low conductivity metals such as aluminum and copper.

    Metal Thickness

    The thickness of the metal can impact your choice of a TIG welder. If you’re planning to weld thin gauge materials, a TIG welder will do an excellent job. On the other hand, you will need a MIG welder when welding thicker metals. But you can always buy an industrial-grade TIG welder that can weld all types of metals and materials.

    Usually, TIG welders can weld steel up to 3/8 inch thick. Also, if you need to weld aluminum or other non-ferrous materials, choose a model that supports non-ferrous metal welding.

    Ampere Rating

    The ampere rating is the maximum output current that your welder can produce. It determines the metal thickness you can weld with the machine, and how fast you can weld it.

    Most TIG welders have an ampere range that you can adjust to your needs with a knob or dial. They’re rated in amps in the 35 to 400 amps range.

    If you’re planning on joining heavy-duty metals such as steel, you’ll need a powerful machine that can deliver up to 400 amps. But if you are working on thinner metals such as aluminum and stainless steel, a TIG welder with an ampere rating of at least 200 is enough.

    However, the best TIG welder should have a high ampere rating. A TIG welder with a higher ampere rating can handle welding projects that require a lot of power.

    Weight

    TIG welders can be heavy, especially if they are more powerful. Although this is not a deal-breaker, it’s a crucial consideration. The weight of the machine will affect its portability and ease of use.

    You don’t want to be carrying around a heavy machine all day and have it hinder your work. But if you only need to weld in one place and the welder has wheels, then the weight becomes less crucial.

    The weight of the machine is also related to its size. It affects the storage space. If you have limited space where you’ll be working, a smaller unit might be better for you. It’s particularly true if you’re working in a small or crowded garage or workshop.

    It’s also worth considering whether the machine has handles. Handles help with transporting it from one place to another.

    Duty Cycle

    The duty cycle refers to the amount of time you can use the welder before it needs a rest. Most machines have a duty cycle of 30%. It means you can use it for three minutes before the TIG welder has to cool down for seven minutes.

    30% is enough for most welding projects. But, if you want to get more done in a shorter period, look for a machine that offers a higher duty cycle.

    But again, you don’t need a high duty cycle unless you plan to use your welder extensively without stopping. Even with the lower duty cycles of some TIG welders, they still perform well as long as you give them plenty of time to cool down between jobs.

    Warranty

    If you’re spending your hard-earned money on a TIG welder, make sure that the manufacturer stands behind the product. That’s why it’s crucial to buy a TIG welder with a warranty.

    Many manufacturers include warranties on their TIG welders, but they aren’t equal. Some welders come with a three-year warranty. Others have a two-year or a one-year warranty.

    Any machine can have issues at some point. So, be sure that the manufacturer is willing to fix any problems. A long warranty also shows that the manufacturer has confidence in their product and doesn’t expect it to break down anytime soon.

    Digital Control

    There are a few features that separate TIG welders from other welding machines. For instance, digital control is one of the leading features TIG welders boast of.

    Digital control keeps the welding machine’s current at a steady rate, regardless of any changes in the input voltage.

    The most common digital control is pulse frequency and pulse time variation. With these variations, you can adjust how the current flows through your machine to suit your needs.

    Digital control is crucial because it gives you more versatility when welding. If you’re using a machine without digital control, you have less freedom to experiment with your welds.

    Type of Ignition

    The ignition type can make a massive difference in welding time. There are two types of ignitions: high-frequency and lift. The high-frequency ignition starts by striking an arc between the tungsten electrode and the weld surface.

    On the other hand, lift starts by lifting the electrode away from the weld surface. You can use either. But, high-frequency offers more control when welding thin materials. It’s because it’s less likely to start at a hot spot.

    It also reduces the amount of contamination in your weld pool because it doesn’t cause spatter. Lift is easier to use on thick materials. It’s because it produces more heat, but it’s harder to get right and may cause spatter with thin metals.


    Conclusion

    If you’re looking for a high-quality TIG welder-of course you want to get the best one, these are high-quality products with great value. All of them come with amazing features and specifications.

    Our top pick is the AHP AlphaTIG 200 Amp TIG Welder. It’s the most powerful and versatile TIG welding machine on the market.
