FAQs – Lincoln square wave 200 problems

How do you set up a Lincoln TIG 200 aluminum?

There is no one-size-fits-all answer to this question, as the best way to set up a Lincoln TIG 200 aluminum may vary depending on the specific application.

However, some tips on how to set up a Lincoln TIG 200 aluminum include ensuring that the machine is properly grounded and using the correct welding rod for the application. Additionally, it is important to set the machine’s amperage and gas flow rate according to the manufacturer’s recommendations.

Does the Lincoln Square Wave 200 have a high-frequency start?

Yes, the Lincoln Square Wave 200 has a high-frequency start. This feature allows the welder to start welding at a higher frequency, which can help improve arc starting and reduce spatter.

What does square wave mean in TIG welding?

In TIG welding, a square wave means that the current alternates between two levels, typically a low level and a high level. The low level is used to initiate the arc, and the high level is used for welding.

The ratio of time spent at the high level to the low level is typically around 50:50 but can be adjusted depending on the application.

What frequency should I weld aluminum?

There is no definitive answer to this question since it depends on many factors, including the type and thickness of aluminum being welded, the welding process being used, and the welder’s experience and preference. However, as a general rule of thumb, lower frequencies are typically better for welding aluminum.

This is because lower frequencies tend to penetrate the metal better, which can help to prevent warping and other problems. Additionally, lower frequencies can help to prevent the formation of oxides on the surface of the aluminum, which can interfere with the welding process.

Do you need high frequency to TIG weld aluminum?

Yes, you need high frequency to TIG weld aluminum. The high frequency helps to create the arc and provides the heat needed to weld the aluminum.

You can use a lower frequency if you are welding thin aluminum, but for thicker aluminum, you will need a higher frequency. If you are using a machine that does not have high frequency, you can use a foot pedal to control the welding current.


While the Lincoln Square Wave 200 has been known to have some problems, it is still a great machine that can provide you with a variety of benefits.
