10 Best TIG Welders - Reviews
1. AHP AlphaTIG 200X 200 Amp TIG Welder - Best Overall Pick
We were impressed by plenty of devices, but none stood out as much as the AHP AlphaTIG 200X. It is, by far, the most versatile TIG welder on this list for producing high-quality welds at an affordable price. The machine has both AC and DC modes, operates at both 110V and 220V, and has an amperage range of 10A to 200A.
Whether you are an amateur or an experienced welder, the AHP device is easy to set up and use. It is one of the most accurate welding machines for thinner materials and is equally good at welding steel and aluminum. It can handle anything between ¼-inch and ⅜-inch of aluminum and steel.
It is sturdy and reliable, but that comes at the expense of its weight, which is 69 pounds. At a size of 19 inches long by 23 inches wide by 12 inches high, it is not highly portable and will excel in a more stationary setting, like a workshop or factory.
The device has plenty of presets for voltage levels and welding modes, making it extremely versatile but easy for even beginners to use. The duty cycle of 60 percent at 200A makes it highly efficient for heavy-duty welding, and it will blast through lighter tasks.
All of its features and the reasonable price make the AHP AlphaTIG 200X our top overall choice. It’s hard to go wrong with this fantastic machine, which can be the cornerstone of your welding needs and your go-to choice for aluminum welding.
2. Mophorn TIG200 200A TIG Welder - Best for the Money
Our recommendation for a budget TIG welder is the Mophorn TIG200 200A TIG Welder. This dirt-cheap multipurpose welder targets people who can’t afford the established brands or need something for a quick task and don’t intend to make a habit of welding. At this price, plenty of compromises are typical. Still, this device offers its fair share of value.
The features are super-basic and limited, but performance is surprisingly stable and consistent. Dual power options of 110V and 220V offer flexibility, as does the 20A – 200A amperage range. A bonus is ability to TIG and stick weld.
It’s hard to talk about reliability and longevity at this price range. Still, most user reviews pit the Mophorn TIG Welder as great value and one of the best TIG welders under $500.

Buyer’s Guide: How to Choose the Right TIG Welder for You
TIG welding is one of the most important and complex parts of fabrication, and it requires a great deal of expertise and appropriate equipment to produce quality welds. Whether you are new to welding or an experienced TIG welder, choosing the right TIG welder for you is one of the most important decisions you will have to make.
Doing thorough research is a must, but don’t worry about it. We’ve done the legwork for you. It’s been a long and tiring process, scouring the internet for TIG welder reviews and using our industry contacts to get professional feedback from welders.
For starters, we have come up with a set of universal criteria to apply when deciding which TIG welder is right for your specific needs. From hobby welding to small home workshops to businesses that require a lot of metalwork in the field, welders' requirements vary significantly.
One of the key technical attributes of your TIG welder is its input power. The input power of a TIG welder directly influences the type of work you will be able to do with your welder. If you intend to use the TIG welder for lighter tasks, then a machine with lower input power might be suitable for you.
The type of material you will weld dictates the kind of TIG welder you purchase and the type of input power it has. Most of TIG welders have automatic AC/DC (alternating current and direct current) adjustability to alter power phases, depending on the type of work required.
A good rule of thumb is to go for high-input-power TIG welders for fusing hard, denser metals, including steel and aluminum, while opting for low-input-power options for softer metals, such as magnesium.
Direct current is more suitable for dense metals, while alternating current is better for less-dense ones. Choose the welder that will fit the majority of jobs you do.
Duty Cycle is the ability of a TIG welder to work without interruption, and it’s a portion of the total active time, which usually is ten minutes for most welding equipment. The duty cycle of a TIG welder is a percentage of that total active time. For example, a TIG welder with a duty cycle of 30 percent can work for three continuous minutes.
The higher the duty cycle, the more time a TIG welder can work without breaks. Breaks are required to avoid overheating of the welding equipment, which drags down the efficiency of the entire process. The quality of the cooling system in a TIG welder determines the duty cycle of the machine.
For commercial and industrial use, TIG welders with a duty cycle of at least 60 percent are the right choice. Home workshops and hobby welders should be okay with TIG welders having duty cycles of 20 percent to 30 percent.
Size and Weight
The weight and size of a welder are crucial, especially if you are looking for a portable machine that you can take with you to job sites. Most welders prefer lighter machines that are easy to store, move around the shop, or take to a job. The weight of a TIG welder depends mostly on the size of its transformer. The bigger the transformer, the heavier the device.
Portability is challenging to define because anything less than 100 pounds is considered a portable welder. But don’t focus solely on the weight of the machine. Look at the quality of handles and carrying mounts, and the presence of wheels for pulling. Light machines can contain low-quality materials that will not last.
Always go for sturdiness and quality handles over just its weight.
The number of features your TIG welder has should reflect the level of experience you have as a welder. Most beginners should opt for machines that have plenty of presets and automized processes, so they can focus on the quality of the weld.
More experienced welders should choose TIG welders that give them more control of the welding process and the ability to program the presets manually.
