AHP AlphaTIG 201XD – A Complete Review with Pros & Cons

TIG welding is one of the most aesthetically and mentally pleasing welding jobs to do out there. It has no waste and spatter production, and therefore has become one of the welders’ favorites. TIG welding is a very intricate work to do that requires a lot of patience, skill, and experience.

Are you looking out for a premium and robust TIG welding machine in the market? Well, don’t remain stranded for long because we have got one of the best TIG welders out there in the market. It is the ‘AHP AlphaTIG 201XD’.

Many of you might ask this very traditional question, “Is it worth the money?”. I can’t say anything about that but you will get an answer to that by reading this product review.


Basic Features

Amperage Reading:

The top left corner of this welding machine has an amperage meter which shows the amount of current entering this device. It is highly useful to many welders.


The AHP AlphaTIG 201XD comes packed with advanced inverter technology with a ‘Pulse Width Modulation (PWM)’. This was easily done by using IGBT technology by the company. You can hardly find this feature in any of the other TIG welders.


You will be surprised to see how many buttons and keys are present on this TIG welder when you take it out of the box. Each and every key has a designated label assigned to them making it easy to read and understand for users. Once you get used to the keys, you will be shocked at how many features they have built into this machine.

AHP AlphaTIG 201XD


This is one of the most featured functionalities of AHP AlphaTIG 201XD and that is its versatility. Being a tungsten-gas welder, it works like a charm when working on alloy steel, stainless steel, thin-gauge materials, and aluminum. It can weld metals ranging from ¼ inch aluminum and 3/8-inch milder steel to 7028 and 6013 steel rods which are thick and enormous.

Dual Voltage:

It is always pleasing to find a welding machine that supports two different voltages simultaneously. It allows the Alpha 200TIG to run at 10V or at 220V. It can also run when there is no generator at a particular location. It performs at 110V as well as performs in 220V which is amazing at this price point.


This welder is compact and light-in-weight weighing around 38 lbs. This makes it highly portable and can be transported or moved from one place to another as required.


It includes an HF start and includes a foot pedal so that you can have a precise Tig control that you wish to have during the entire welding process to produce spatter-free welds. It supports a variable range of power input from 10-200 amps and a pulse frequency of 5.5. The pulse time it has is around 90%.

The stringer cable is about 9.5 feet long and the power cord is 6 feet which is a surplus for a welding machine. As the foot pedal is lighter than usual foot pedals, you will need to work around a little bit to get used to it.

Design and Value

The AHP AlphaTIG 201XD is a pretty tall and elegant but plainly designed welding machine. It is a little big in size than expected. Being not the most beautiful welders in the market, its price and functionality prove its worth to all the welders out there.

Boasting a lot of features, technology, equipment, and hardware that makes the TIG welder get any kind of TIG welding jobs done. Along with the capabilities to do pulse, stick as well as TIG welding, you can weld thin and thick metals, and also it is highly compatible with light, medium, and heavy-duty welding duties. It has a ‘carry handle’ on its top that makes it easy to carry around wherever you go.

This machine is an update to the previous beast. It is the same old product which was super-stable and functional by all means and they improved the performance even more by making this model. It was engineered with some new technology like ‘Pulse Width Modulation (PWM)’ and ‘Inverter Technology’.


If you are working with steel alone, then DC is more than enough. But if you wish to work with aluminum, then you would wish to use AC for the best results of your weld. And this welder provides that dual functionality uses both types of current. This AC welding method helps you clean the oxidation stuff on the weld and the whole metal.

The arc stability is just very useful when using this IGBT technology as it allows a 60% duty cycle because of which you can weld using the machine for very long hours and the device will not get overheating by doing so. It can also handle metals between ¼ inches aluminum to 3/8 inches mild steel.
