Lincoln Square Wave TIG 200 Review

Our topic today is Lincoln Square Wave TIG 200. Let’s examine what makes this equipment essential for welders, especially those who own a welding business or weld pretty often. In this review, we will discuss all the available features, the quality of its performance, and everything it has to offer. Knowing what the Lincoln Square Wave TIG 200 is capable of, you can decide whether this machine is the right one for you. Let’s start reviewing!

Lincoln Square Wave TIG 200 Features

TIG and Stick Capability

By offering TIG and Stick welding options, the Lincoln Square Wave 200 is very versatile. Including aluminum in the range of materials allows for a greater variety of work. If you want the bead to be more precise and on point, use the TIG option. With Sticks, you can weld thicker materials when aesthetics are less important. It is also possible to Stick weld outside.


DC or AC power can be used to control the welder. DC TIG is a better option than AC TIG for welding aluminum, steel, and chrome-moly.


A 120V or 230V household outlet can be used with this dual-voltage device. Power cords for each voltage are provided, making switching voltages simple. The Lincoln TIG 200 has great power and portability. Here is not the end, you will also learn the solution to all lincoln square wave 200 problems in this lincoln tig 200 review article.

Simple Interface

There are so many complicated components on some welding machines The setup of the controls is so confusing. Initially, the Square Wave 200’s rules can seem intimidating to a beginner, but after a few minutes, it’s easy to figure out. The interface includes the following controls:

  1. You can turn it on and off.
  2. You can adjust your settings by clicking on the top right button. The AC balance, pulse frequency, and frequency of the AC circuit can all be changed.
  3. On the interface, you can adjust the setting with the large knob in the center.
  4. Additionally, under the setting selector, there is an option to select the welding process: AC TIG, DC TIG, or stick.

AC Balance

Using the AC balance feature, you can better control your weld. You can adjust the electrode negative (60-90%en) of this unit. Lower electrode negatives are desirable if you need a thicker beard, a more powerful cleaning action, and shorter tungsten life. Welders need a higher electrode negative if they need deeper penetration, a narrower bead, higher gas flow speeds, or better aesthetics.

AC Frequency

Frequency refers to the number of changes from positive to negative in the current per second. This welder offers 60 to 150 Hz. The bead is broader with a lower frequency. The dot becomes narrower and more focused with a higher frequency.

Pulse Mode

A constant current can be replaced with pulses. .1-20 pulses per second are possible for the Lincoln Square Wave 200. For moderate amounts of filler metal, choose a lower frequency. You should select a higher frequency if you want minimum distortion. A higher AC frequency allows better control of welding thin materials.

High-Frequency Start

A high-frequency start begins an arc without contacting it. As a result, the torch does not come in contact with the workpiece, reducing contamination. A disadvantage of this method is that it’s one of the most advanced. It may interfere with nearby electronics due to its high frequency. Just keep your phone out of your pocket and away from all electronics in the work area.

Inverted Based Design

A smaller box can store more power with inverter technology. It is thanks to Lincoln TIG Welder technology that a 46-pound unit can pack 200 amps of power. The energy was stored and dispersed by an internal microcomputer. This welding machine is also portable, thanks to the technology. You can use it anywhere as needed for your job. Adding a wheeled cart makes it even easier to move around.

Frequently Asked Questions

Is the Lincoln Square Wave 200 an inverter?

It is based on inverted symmetry. The inverter technology holds more energy in a smaller package. In a 46 lbs unit, this technology allows the team to produce 200 amps of power.

Can you TIG weld with a Lincoln SA 200?

Argon should be turned on and off with the valve of the torch before striking an arc. Tig welding is our only use of our SA-200s. You can easily set it up. A gas lens would seem to be the best option.

Final thoughts

In this Lincoln Square Wave TIG 200 Review, You get an excellent price-performance ratio with the TIG 200 AC/DC since Eastwood marketed it aggressively. This is true even when a stick electrode holder is added. As a bonus, the Lincoln has a machine with a duty cycle that is twice as long. With the Eastwood machine, the torch comes with a trigger switch and pre-and post-gas flow controls. With its more expensive offering, Lincoln Electric is less likely to provide either of these features. 

Their TIG welder has a complete duty cycle as well. It is advisable to get a TIG 200 AC/DC if you plan on welding a lot. TIG 200 AC/DC was once known for its lousy foot pedal. As a result of the July upgrade, you now have a foot pedal similar to the Lincoln model. 

It has a clear digital display and easy-to-use controls that simplify the welding process. With the included pulse control, you can fine-tune your arc quickly and easily. TIG 200 from Square Wave makes learning curves shorter for rookies.
