2018 AHP AlphaTIG 200 X 200 Amp IGBT AC DC Tig-Stick Welder with PULSE 110v 220v 3 YEARS WARRANTY

The reason behind recommendation about the AHP brand welding system is as it has a long history to take the welding science into a new era. AHP has a significant contribution to introducing welding techniques from its primary stage to a high-end scene. It has involved in manufacturing different welding device on TIG, Stick and Arc, MIG, Plasma Cutter and various accessories that are necessary or of interest of welder from a minor to industrial ones. AlphaTIG 200x TIG/Stick welder is one of the vital product of AHP welder company backup by three years extended warranty.

AHP Welding System first introduced AlphaTIG 200x on 2014 (as per copyright information), then they modified and upgraded it in 2016, 2017 & last 2018. The major upgrade in pulse frequency from ±5 Hz to 200 Hz, improved quality torch and pedal used in the 2018 model. However, we try to discuss more details in our ahp alphatig 200x review, and 2018 alphatig 200x review helps to compare the best options among the two models.


Diversified Uses:

The best part of a welding machine is its quality of the weld. Alphatig 200x is constructed in such a way that it can weld any metal from stainless steel to aluminum very well. The most remarkable side of this machine is, it can weld thin metal smartly and efficiently. Whereas, most of the welding machine available on the market can do weld of thick materials, but they cannot work well on thinner elements. Alphatig 200x can weld thinner gauge metals like ¼ inch aluminum or ¾ inch steel as like an expert. It can also weld 6013 and 7018 powerfully.

It will also support you to do any job like little welding at home repair, hobby welding, artistic or any industrial welding. Whether you are a greenhorn or an experienced welder, it will work like surprising.

Proper Control:

Control over a device is an essential aspect of getting a better result as well as safety reasons. Luckily, Alphatig 200x comes with a comfortable foot pedal control which allows you to weld with both hands. Thus it helps you to get precise welding as you no need to worry about operate the device with one hand.

HF start TIG along with foot pedal makes the alphatig 200x more convenient to operate and control. It also has anti stick control and 2T/4T torch trigger control panel along with others controller.

Advanced Inverter Technology:

The welder adopts a rectifier which designed with advanced inverter technology. The Alphatig welder derives the inverter technology from the inverter power theory and devices. The inverter is an electronic circuit which transforms DC power to AC and controls input voltage, output voltage, and frequency. The IGBT inverter technology uses high power to turn the working frequency of 50/60Hz to high frequency like 20KHz or higher. As of this technology Alphatig 200x can weld a wide range of materials with accuracy and cleanly.

Stick Welding:

Powerful 200Amp AC/DC alphatig welder has an option for stick welding too, which allows the beginners or professional to gather a wide range of welding experience. Stick welding system also facilitate you to do welding work in an adverse situation like in windy condition, welding pipes at outdoors, and where need speedy welding.

Full Range of Starting Amperage:

You will get a wide range of ampere control in AHP Alphatig. In case of TIG welding the amperage range is 10-150A in 110v and 10-200A in 220v single phase power source. In case of Stick or MMA welding, the amperage range is 30-145A in 110v and 30-195 in 220v current. It will allow you to get the perfect result of welding in a wide range of sticky and non-sticky materials.

Flexible and Portable:

If you look at it, you may think why I discuss this particular point about Alphatig, as it seems too bulky. However, it is not too hard to move around as it is about 38 pounds. If you use it at your workshop or small repair maintenance of household appliances, you may not need to travel it extensively. If you use it for any welding project which requires frequent movement from site to site, hope it will not be so severe to drive it with your single effort.


Alphatig can perform its work in 1/8″ (3 mm) thickness metal at 40-80 amp power supply up to 3/8″ (10 mm) thick metal with 200 amp which is an excellent performance for any welding machine. It has the flexibility to use different electrodes, diameter from 1/16″ to 5/32″ based on metal thickness. Superior performance is guaranteed by this Alphatig 200x as it can work on both 110v and 220v, all fantastic features, versatility, and improvisation of advanced technologies allow you to do lots of welding job. If you are looking for a robust, resilient and comfortable product, this is the best choice for you.
