Lotos TIG200ACDC specs at a glance

The Lotos TIG200ACDC is a well-crafted welding unit that offers an impressive list of features. Its features include:

  • 200 amps AC/DC output current with pulse frequency and pulse width control, which allows for precise welding on different materials such as aluminum, stainless steel and copper.
  • Foot pedal control for added convenience and accuracy.
  • Torch control with variable current ranging from 10 to 200 amps.
  • Automatic Arc Force Control (AFC) for smooth arc starts, steady arcs and better puddle formation.
  • High frequency start for precise arc starts without sticking or tungsten contamination of the weld pool.[2]

Design and Portability

The Lotos TIG200ACDC is a medium-duty machine that boasts a lightweight design, weighing only 44 pounds. This makes it easy to move around your workspace and take with you. It also has a sturdy metal housing that provides protection against wear and tear. The welding gun handle is comfortable to grip and the digital readout allows you to easily adjust the current, voltage and other settings.

The one downside of this machine is its size; it’s not designed for portability. This is because it has a large enough power supply and cooling system that makes it too cumbersome for one person to move. If you are looking for a portable TIG welder, you may want to look elsewhere.[2]


The Lotos TIG200ACDC is a powerful unit capable of welding up to 200 Amps. Its duty cycle is 60% at 150A, 30% at 175A and 20% at 200A. It features AC/DC aluminum welding capabilities, allowing the user to weld aluminum up to 1/4 inch thick with ease. The unit also comes with built-in foot pedal control and a torch length adjustment feature.

This TIG welder produces clean, precise welds every time, making it an ideal choice for both experienced professionals and those new to welding. With the addition of a pulse frequency setting, users can easily adjust the amperage for better control over the welding results. The high frequency start helps to strike an arc quickly and easily, ensuring that users can get started on their projects with minimal effort.[2]

TIG welder unboxing

When you unbox your Lotos TIG200ACDC, you’ll find a few components inside. This includes the welding machine itself, an AC/DC foot pedal unit, a ground clamp, an electrode holder and torch cable assembly with gas regulator hose, two argon gas regulators (one for AC and one for DC), two ceramic cups, two collets, two collet bodies and a set of TIG welding accessories.

The welder itself is made from an all-aluminum casing and features a digital display for adjusting your settings. The foot pedal unit comes with three buttons – one for increasing the current output and the other for decreasing it. It also features a control knob so you can adjust the amperage to your liking. The ground clamp is easy to use and provides a secure connection for welding projects.[2]

Full-size TIG platform

The Lotos TIG200ACDC is a full-size TIG platform designed for welding professionals. It offers up to 200 amps of power, allowing you to weld aluminum and other metals more easily than ever before. The built-in adjustable pulse frequency makes it easier to control the heat output and fine-tune your welds.[2]

Making spatter

Spatter-free welding is a great way to get clean and professional looking projects! It can be a bit tricky, however, so here are some tips for making spatter-free welds with the Lotos TIG200ACDC:

  • Use the right electrode – Make sure you choose an appropriate sized electrode for the material you are welding. Too small an electrode can cause spatter, while too large an electrode can cause lack of penetration into the base metal.
  • Increase amperage – Increasing your amperage will help reduce spatter by increasing the amount of heat generated in the weld puddle. However, be sure not to increase the amperage too much, as this can cause welding defects such as porosity or slag inclusions.
  • Use a “drag” technique – Using a dragging technique (moving the electrode away from the weld puddle) will help to reduce spatter by allowing more time for heat to penetrate into the base metal and reduce the overall amount of heat generated.
  • Adjust your travel speed – Make sure you adjust your travel speed to match the amperage and electrode size you are using. Too slow a travel speed can cause excessive spatter, while too fast a travel speed can result in lack of penetration into the base metal and incomplete fusion.[2]

Reversible drive rolls

One of the most useful features of the Lotos TIG200ACDC is its adjustable reversible drive rolls. The adjustable forward/reverse speed control allows operators to fine-tune the welding process for best performance and results.

Reversible drive rolls

This ensures that each weld is as perfect as it can be, making it ideal for precision welding applications. It also helps to reduce the risk of accidents due to unexpected changes in direction. This is an invaluable feature that sets this welder apart from others on the market.

Hinged door

The Lotos TIG200ACDC comes with a hinged door cover that allows you to access the internal components and make adjustments or repairs. The cover is made of heavy-duty steel and has a powder coated finish for added protection against corrosion. The unit also features an adjustable airflow system, which helps to ensure optimal performance. Additionally, the hinged door cover makes it easier to access the internal components and make any necessary adjustments.

Power output

The Lotos TIG200ACDC has a 200-amp AC/DC output power, allowing for both alternating current (AC) and direct current (DC) welding.

It is capable of welding up to 3/8″ aluminum and stainless steel as well as 1/4″ mild steel.
The output power also allows for more precise welds, with less heat buildup.[1]

Weight and Transportation

The Lotos TIG200ACDC is lightweight and easy to transport. At only 38 pounds, it’s light enough to carry around easily, even up stairs! The compact design makes it perfect for tight spaces. It also comes with a handy carrying handle, making it even easier to transport.[1]

Wire Speed and Voltage Settings

The Lotos TIG200ACDC comes with a variety of pre-set wire speed and voltage settings. This makes it easier to adjust the device to fit your application. Setting the correct wire speed and voltage is essential for optimal performance. To get started, you’ll need to set the Wire Feed Speed (WFS) knob on the front panel. You’ll also need to select from the four voltage settings of between 13-25 volts on the back panel.[1]

System setup

The Lotos TIG200ACDC is a complete welding system, which includes all the necessary pieces to get started. It comes with an AC/DC inverter, foot pedal, air cooled torch and argon regulator/flow gauge. The setup process is simple and takes only minutes. All you need to do is attach the gas hose to the regulator and attach the power cable to a wall outlet. Once you have everything hooked up, you can adjust the settings to your desired specifications.[1]
