The Complete Guide to Selecting the Correct TIG Welder for Your Purposes

For professional welders and DIYers alike, choosing the appropriate TIG welder can be crucial to producing clean and accurate welds. Because of this versatility and precision of operation, TIG welders are important when working with applications that involve thin materials and metals including stainless steel and aluminum. Selecting a suitable TIG welder takes into account many available options, such as the Pulse TIG machine, Cold TIG machine, and various levels of gas controls. Before buying a TIG welder, you must be able to determine which type of welder will fit your needs. This guide provides all pertinent materials you need in order to select the appropriate TIG welder for your application.

What is TIG Welding and Why Would One Choose to Use It?

TIG, or Tungsten Inert Gas, welding uses a non-consumable tungsten electrode to create the weld and a shielding gas to keep the weld area free from contaminants. The ability to use the non-consumable electrode along with the shielding gas creates a higher degree of precision and control than welding with traditional methods. Because of this superior degree of precision and control provided by the TIG process, it is used to fabricate detailed products and to weld very thin materials. The reasons to choose TIG Welding are listed below:

• Precision: Providing excellent control of your welding arc will produce welds that are high quality and clean.
• Versatility: The welding process can be used on a variety of materials including stainless steel, carbon steel, aluminum, etc.
• Low Heat Input: The welding technique produces very little heat with regard to thin material and will not warp when welded.

Critical Features of a TIG Welding Machine

There are many features to consider when looking for a TIG welding machine. It is critical for you to know what the critical features are in order to select a welder that is tailored to your welding needs. Here are some features that most welders need:

PULSE TIG Functionality

A Pulse TIG welder allows the user to manipulate the number of pulses per second. This helps control the heat applied to the base metal and also makes it much easier to weld thin materials without burning or warping them. This feature is excellent for welding intricate designs and offers much more control of the heat output.

Cold TIG Setting

If you are welding delicate materials that can easily be damaged by excessive heat, then you will benefit from a welder equipped with a Cold TIG mode. The Cold TIG mode delivers a welding arc that puts out very little heat allowing the metal to maintain its integrity and produce a clean weld.

Foot Pedal Control

A foot pedal will give you real-time control over amperage allowing you to keep both of your hands free. This is a particularly helpful feature when welding detailed designs or adjusting your weld settings for accuracy.

Advanced Gas Controls

It is best to select models that provide the ability to adjust pre-gas delivery and gas delay settings. This contributes to a more consistent outcome and helps create a very strong weld when starting and stopping the weld.

Modes 2T or 4T with a Memory Function

With modes 2T or 4T, you will have the capability to switch between multiple operating modes for your welding torch. Some of these machines also have the capability to record your preferred settings in memory, allowing you to duplicate the welding process for a consistent result each time.

Safety Features

Keep safety first by using the many features on this type of welder that protect you and your machine from overheating or over-current conditions; which will assist you with longer runs of welding.

Who Would Benefit from a TIG Welding Machine?

The TIG welding machine is not for everyone, but is the perfect choice for both professionals and hobbyists looking to create high-quality welds. Consider purchasing a TIG welding machine if:

• You work with stainless steel, aluminum or thin-gauge materials on a regular basis.
• Your application is more tolerable of precision with regard to welding, such as automotive repair, aerospace fabrication, or decorative iron.
• You desire to limit your spatter while welding for aesthetics.

Recommended TIG Welding Machines

When you decide to purchase a TIG welding machine, consider one of the following highly-rated options:

TIG-205P

The TIG-205P is known for being one of the most versatile welding machines available on the marketplace today! In addition to being a very versatile machine, it is equipped with several advanced capabilities including: Pulse TIG, Cold TIG, and MMA welding modes, as well as having a foot pedal for adjusting voltage (amperage) using your feet. Due to its adjustable pre-gas, slope up and down, and gas delay functionality, it is the perfect machine for both professional and hobby welders.

Commonly Asked Questions About TIG Welding

What is the difference between TIG welding and MIG Welding?

TIG welding uses a tungsten electrode that does not become a part of the finished weld, as well as an inert gas that provides the shielding for the weld pool, whereas MIG welding uses a wire electrode that is continuously fed during the welding process as well as a gas to provide a shielding of the weld pool. The end result is that TIG welding allows for a detailed and clean finish while MIG welding allows for faster production of larger projects.

Which gas is used for TIG welders?

In general, the majority of TIG welding is performed with argon gas or a mixture of argon and helium to protect the weld pool from contamination. However, the specific gas required will depend on the type of materials being welded.

Can I use a TIG welder to weld aluminum?

Yes, but you must ensure that the TIG welder you are using is capable of performing AC (alternating current) welding, which performs the cleaning action that is required for welding aluminum.

How can I avoid warping of thin materials?

If you are welding thin materials, be sure to use Pulse TIG and set the amperage for the specific thickness of the material properly. Also, rather than concentrating the heat of the torch in a specific area, try to spread out the heat by moving the torch evenly around the surface.

Is using a foot pedal a must?

A foot pedal is not necessary for all forms of TIG welding; however, using one provides much better control of the welding amperage, which is invaluable for detailed welding projects.

Summarize

When choosing a TIG welder, there are many factors to consider including your specific needs, materials to be welded, and amount of features required. The use of advanced features (e.g., Pulse TIG, Cold TIG, Foot Pedal Control, and Adjustable Gas) will make your welding experience much easier, resulting in producing professional-grade welds. The TIG-205P, TP-220AC/DC, and TIG-250PL are all excellent options worth considering. Invest in a quality TIG welder today and turn your ideas into high-quality welds with great speed!
