A good, powerful welding machine can make it easier and more convenient to handle welding operations. TIG welders are used often for welding thinner metals or in extremely cosmetic applications, which need strict control of heat. With the progress of welding applications and technology, TIG welding is fast becoming popular.
It offers clean and fast welding with very less amount of smoke and minus any spatter. While looking for a TIG Welder, you need to consider a wide variety of factors. It is much more than just looking at the appearance or price point. You need to choose a welder that is fit for your purpose, is strong and durable and has the best price tag for your budget.
There are various TIG welders available today, for professionals as well as hobbyists. Read on and know about some of the best TIG welders available on the market, and how to choose the best ones among them.
How to Choose the Best TIG Welder?
You need to consider various factors while choosing the TIG welders
- Look for a welder with the widest amperage range at an affordable price. A TIG welder with a very narrow range of amperage can severely restrict the variety of materials that you can weld.
- Those with 5 – 230 Amp range can offer you the flexibility required for welding on thin materials, like aluminum with ¼ inch thickness or 24-Gauge stainless steel.
AC and DC welding
- In case you want to weld materials apart from stainless steel or steel, the TIG welder has to offer DC (direct current) as well as AC (alternating current) options. For instance, you need to use AC for welding magnesium, aluminum, and other soft, self-oxidizing metals.
- You will require DC for welding deoxidized copper, stainless steel, steel and other hard metals.
- For proper TIG welding, heat control is an important factor. Control of the heat input on thinner materials can lower the metal warping. Pulse welding can control heat input into weld without any sacrificing of weld penetration.
- Pulsed TIG welding makes welders alternate between a lower background current and a higher peak current. This helps maintain the arc and allows cooling of the welded joint.
Ease of use
- TIG welding involves a lot of skills although that does not mean that it should be complex in usage.
- Look for ones that are user-friendly and come with controls that can easily be understood.
Foot amperage controls
- Those with foot amperage controls are important, particularly for aluminum welds.
- More amperage is needed for making the process simpler and letting users reduce or increase the welding amperage as required.
- Many TIG welders have additional features that can increase their longevity and durability.
- Look for those with a cooling fan, which can run constantly to keep the welder cool. Or you can choose one with a fan that runs once the welder heats up and a thermostat is tripped.
Removable TIG torch
- You should also choose the TIG welders that come with a removable TIG torch that can be changed fast. At times, during TIG welding, you might like to change your torch to lightweight and smaller torch, a pencil torch or a longer torch for dealing with different types of welding operations.
- In case the torch is wired permanently to the welder, you will have to do with just one type of torch.
Tig Welder Review
1.TIG Welder, Dynasty 200 SD
- This is a perfect welder for various purposes, such as ship/boat, mechanical getting, manufacturing, aviation and various other projects. It offers better overall performance on almost any type of input voltage.

- It is just 23 kg or 50 pounds in total weight and you can move it conveniently without the need for any other individual.
- One of the TIG welders, it can weld really well and can be ideal for anyone who wants to handle light to moderate welding tasks.
3. LONGEVITY Tigweld 200sx
- The device has a stick welder with 200 Amp rating. It is easily portable and you can easily move it around for welding in different areas. You can use it to weld on 220 V as well as 110 V power.
- The unit can be plugged into a 5000-watt generator to weld in remote or rural locations. It can weld 6013, 7018 and various other types of stick welding electrodes.
- It has a foot pedal to control TIG welding and operations and comes with high frequency start TIG as well. You can weld aluminum by flipping a switch in air conditioning mode. This is the exact TIG welder for aluminum.
4. Lotos LTPDC2000D
- It comes from Lotos Technology, a prestigious name in the manufacturing of arc (MMA) welding, TIG/stick, and plasma cutting equipment.
- It can cut any type of metal up to a thickness of ½ inch. It has 50 Amp plasma cutting ability and has a 60% duty cycle at maximum amps for any activity.
- It has a bigger TIG welding torch, with short and well as long caps. With 50 Hz / 60 Hz input power frequency, it performs very well. It must be noted that the performance is better at 60 Hz.
- Although it is designed for DIY enthusiasts and commercial users, it can satisfy the needs of even professional welders.
Types of TIG Welders
TIG Welders can be typically classified into 5 main types:
1. Power I-TIG 200
- It is the TIG welder for the money and ideal for portable fabrication and repair. It offers a stable DC arc. You can run it on most of the modern generator welders. It can easily handle mild steel and stainless steel. Its full panel control and pulse control makes it perfect for operating extended length torches in any place.
- With the stable and smooth arc of the SMAW or stick function and along with arc force control, it offers a substitute to TIG in less than ideal situations.
- It usually arrives with all the accessories that matter, such as regulator, cables, torch and foot pedal.
