III. How to Choose the Best TIG Welders?

Before you buy a TIG welder for industrial use, you need to consider some important factors that will affect your welding quality and efficiency. Here are some of the things you need to look for when choosing a TIG welder:

  1. Power output: The power output of a TIG welder determines how thick of metal you can weld and how fast you can weld it. Generally, the higher the power output, the better the welding performance. However, you also need to consider the power source and the power consumption of the machine. You need to make sure that the machine can run on the available power source in your workplace and that it does not consume too much electricity. A good rule of thumb is to choose a machine that has at least 10% more power output than the thickest metal you plan to weld.

  2. Duty cycle: The duty cycle of a TIG welder refers to how long the machine can run continuously before it needs to cool down. It is expressed as a percentage of the time that the machine can operate at a given amperage in a 10-minute cycle. For example, a machine with a 60% duty cycle at 200 amps means that it can run for 6 minutes at 200 amps before it needs to rest for 4 minutes. The duty cycle is important because it affects the productivity and efficiency of your welding. You want to choose a machine that has a high-duty cycle at your desired amperage so that you can weld for longer periods without interruptions.

  3. AC/DC capability: The AC/DC capability of a TIG welder refers to whether the machine can switch between alternating current (AC) and direct current (DC) modes. This is important because different metals require different types of currents for optimal welding. Generally, DC is used for welding steel, stainless steel, copper, brass, and other ferrous metals, while AC is used for welding aluminum, magnesium, and other non-ferrous metals. AC is also used for cleaning the oxide layer on aluminum before welding. You want to choose a machine that has both AC and DC modes so that you can weld various metals with ease.

  4. Arc start features: The arc start features of a TIG welder refer to how the machine initiates the arc between the tungsten electrode and the metal. There are two main types of arc start features: high-frequency start and lift start. High-frequency start uses an electric spark to create an arc without touching the metal, while lift start requires touching the metal briefly and then lifting the electrode to create an arc. A high-frequency start is preferred because it produces a more stable and consistent arc, reduces tungsten contamination, and prevents sticking or scratching of the metal surface. However, high-frequency start may interfere with some electronic devices or sensors in your workplace, so you need to check for compatibility before using it.

  5. Pulse function: The pulse function of a TIG welder refers to whether the machine can modulate the current between high and low levels during welding. This creates a pulsing effect that helps control the heat input and output of the weld, resulting in better penetration, less distortion, less spatter, less warping, and less cracking. The pulse function also allows you to create different patterns or effects on the weld bead appearance by adjusting the frequency, width, and peak current of the pulse. You want to choose a machine that has a pulse function so that you can improve your welding quality and versatility.

  6. Portability: The portability of a TIG welder refers to how easy it is to move or transport the machine from one place to another. This depends on factors such as the weight, size, shape, handle, wheels, or cart of the machine. Portability is important because it affects your convenience and flexibility in your workplace. You want to choose a machine that is lightweight, compact, ergonomic, and easy to carry or wheel around. You also want to choose a machine that has a long and flexible power cord and torch hose so that you can reach different areas without hassle. Some machines come with a carrying case or a cart that makes portability even easier.

TIG welding is a complex and demanding process that requires a lot of skill and practice, but it also depends on having the right equipment for the job. If you are looking for the best TIG welders for use, you need to consider several factors, such as the power output, the duty cycle, the AC/DC capability, the arc start features, the pulse function, and the portability of the machine. In this article, we have listed the best 5 TIG welders on the market and provided you with a buyer’s guide to help you make an informed decision.
