In brief: Lotos TIG 200 Welder Review

The Lotos TIG 200 is a dual-voltage TIG welding machine that can be used for domestic, DIY and medium-duty industrial or commercial jobs. The machine also features a square wave inverter which enables the welder to be more accurate. The TIG 200 can be used in two voltages of 220V and 110V and is capable of performing TIG and Stick welding as well.

The Lotos TIG 200 can be used to weld stainless steel, mild steel, aluminum, and other metals to a maximum weld thickness of 3/8 inches.

The product’s square wave inverter allows accurate welding of aluminum materials.

The welder can produce AC as well as DC output.

The TIG 200 is manufactured by a California-based company Lotos Technology that has been active since 2007.

Lotos are producers of welding and cutting tools for domestic and small-scale commercial use.

The machine requires argon to perform TIG welding.

The machine is not stackable in design but the machine features a foot pedal accessory that can be used for regulating welding heat during the process.

How to use the Lotos TIG 200 Welder

The machine should be properly grounded before use. The machine requires Argon for TIG welding but not for the Stick welding process.

A user would also require stainless steel wire welding brushes for each material to be welded.

The machine automatically detects the power source and can differentiate between 110V or 220V power source.

The machine has an Argon Gas Regulator which helps the user control the volume of gas.

The welder has switched on the panel with instructions on when to use them, these include switches for TIG and Stick Welding.

The user should note that for welding non-aluminum materials machines should be run in DC mode, and similarly, for aluminum materials, the machine should be switched to AC.

A foot pedal is also provided in the product package which can be used to precise welding heat control.


The company provides a 1-year warranty from the date of shipment, for all the parts of TIG 200 unless stated otherwise.

It is also suggested by the company to only use identical replacement parts and only the accessories that are compatible with the welder.

A user can contact the company on the company’s mail which is [email protected].

Our Recommendation

The Lotos TIG 200 is a robust mid-ranged welder that can be used for all sorts of materials.

The welder would be a good upgrade over a number of smaller and cheaper welders, as it possesses a number of features that are usually found in much more expensive and heavy-duty industrial welders.

The machine can also automatically switch between 110 and 220 Volts depending on the power required.

The machine is reliable and is fairly easy to use due to the many features like a foot-pedal for regulating welding heat, and self-switching voltage settings.

We would recommend this product for all DIY projects, domestic repairs around the home or garage, or light to medium-duty fabrication jobs.
