TIG welding and stick welding (also known as SMAW – Shielded Metal Arc Welding) are both popular methods in the world of welding, but they use different equipment and techniques. However, many wonder if it’s possible to perform TIG welding with a stick welder. While a stick welder is not inherently designed for TIG welding, the answer is yes, in certain circumstances, and with the right modifications.

Understanding Stick Welding and TIG Welding

Before diving into the specifics of using a stick welder for TIG, let’s briefly look at the two welding processes:

• Stick Welding (SMAW): An electrode coated with flux is used in this manual arc welding procedure. The electrode melts to form the weld pool, and the flux provides shielding to protect the molten weld from contaminants in the air. Although it is flexible and works with a variety of materials, it may not be as accurate as TIG welding.
• TIG Welding (GTAW): TIG welding, on the other hand, produces the arc using a non-consumable tungsten electrode. The welder also needs to feed filler material into the weld pool manually. Thin materials like titanium, aluminum, and stainless steel are frequently welded using TIG welding, which is renowned for generating accurate, high-quality welds.

Can a Stick Welder Be Used for TIG Welding?

While stick welders and TIG welders are fundamentally different, some stick welders can be converted to perform TIG welding with the right modifications and attachments. Here’s how this can be achieved:

• TIG Welding Attachment for Stick Welders: Ensure that your welder can provide the necessary amperage range for TIG welding. TIG welding requires precise control of the amperage, usually lower than what is needed for stick welding. Many modern stick welders can be converted into basic TIG welders by adding a few essential components. These include:
  • A TIG welding torch that allows you to control the arc and the filler material.
  • A gas valve to control the shielding gas flow.
  • A tungsten electrode suitable for TIG welding.
• Inert Gas Supply (Argon): An inert shielding gas is necessary for TIG welding in order to prevent contamination of the weld. The gas typically used is argon, or a mixture of argon and helium. For stick welders to function for TIG welding, you’ll need to:
  • Pair the welder with a gas tank filled with argon gas.
  • Use a flow meter to regulate the gas flow to the welding area, ensuring that the shielding gas effectively protects the weld from oxidation and contamination during the process.
• Amperage Control: TIG welding demands precise control over the welding current. This level of control is often more specific and lower than what is required for stick welding. For successful TIG welding with a stick welder:
  • Many stick welders offer adjustable amperage settings, which can be fine-tuned for TIG welding.
  • If your stick welder lacks the necessary control, you might need an external remote amperage control box to make adjustments and ensure the precise current needed for smooth, high-quality TIG welds.
• Considerations for the Material and Technique: TIG welding is often used for more delicate or intricate projects, such as working with thin sheet metal or fine components. However, achieving the same precision with a stick welder may be more difficult:
  • Stick welders may not provide the fine control needed for thin materials or delicate work, especially compared to dedicated TIG welders.
  • The quality of the weld depends on the welder’s ability to produce a stable, smooth arc, which may be harder to maintain with a stick welder.
  • While converting a stick welder for TIG welding can be effective for smaller or less intricate jobs, it may not offer the same level of performance and results as a dedicated TIG machine.

Benefits and Drawbacks of Stick Welding for TIG

For some welders, using a stick welder for TIG welding might be a sensible choice, but it’s important to consider the benefits and drawbacks. Here’s a more in-depth look at the pros and cons:

Pros

• Cost-Effective: Stick welders are generally more affordable than dedicated TIG welders. If you already own a stick welder, converting it into a TIG welder can save you significant money.
• No Need for a New Machine: Instead of investing in an entirely new TIG machine, you can repurpose your existing equipment with a few additional components. This can be especially useful for hobbyists, small shops, or those with a limited budget.
• Versatility: Steel, cast iron, stainless steel, and other materials may all be worked with by stick welders. This makes them ideal for outdoor and heavy-duty applications.
• Expanded Functionality: By adding TIG capabilities, you effectively expand your machine’s range of functions, allowing you to handle both heavy-duty stick welding jobs and more delicate, high-quality TIG welds.
• Portability: Stick welders are compact and portable, making them ideal for use in various environments, including construction sites and remote locations.
• No Major Impact on Portability: Adding TIG functionality doesn’t significantly affect the portability, so you can take your modified welder with you without much extra hassle. This is especially useful for welders working in mobile or field situations.
• Ease of Use for Basic Tasks: Stick welding is relatively easy to learn, and converting to TIG welding can be useful for less intricate TIG jobs.
• Suitable for Hobbyists: Beginners or hobbyists who want to experiment with TIG welding can do so without buying an expensive TIG welder, making it a more accessible option.

Cons

• Limited Control: Stick welders do not offer the same fine control over the welding arc as dedicated TIG welders. This can lead to less consistent welds, especially when working with thin or delicate materials.
• Heat and Amperage Issues: The inability to precisely control heat and amperage can cause issues like burn-through or uneven weld beads, particularly when working with lighter gauge materials. TIG welders provide much finer adjustments for optimal weld quality.
• Additional Equipment: To convert a stick welder for TIG welding, you’ll need to purchase several attachments and accessories, such as a TIG torch, a gas regulator, a flow meter for argon gas, and a suitable tungsten electrode. These add to the upfront cost of conversion.
• Ongoing Costs: It might take a lot of effort to maintain and set up the extra equipment on top of the initial outlay. You’ll also need to manage consumables like tungsten electrodes and shielding gas, which may increase your long-term costs.
• Not Ideal for High-Precision Applications: While a stick welder converted for TIG can handle basic TIG tasks, it is not suitable for high-precision applications. This is especially true when working with thin materials, tight tolerances, or intricate designs that demand perfect, clean welds.
• Lack of Advanced Features: Dedicated TIG welders offer advanced features such as high-frequency arc starts, more stable arcs, and foot pedals for precise amperage control, all of which a stick welder lacks. This makes stick welders less reliable for tasks requiring high-quality results.
• Learning Curve: TIG welding requires a higher level of skill compared to stick welding, particularly in maintaining a stable arc and feeding filler material.
• Challenging for Beginners: Even with a converted stick welder, the learning curve for TIG welding remains steep. Some welders may find it more difficult to achieve clean, professional-looking welds with a stick welder, especially without the advanced controls and smooth arc provided by a dedicated TIG welder.
• Inconsistent Results: Due to the limitations of a stick welder, welds can be less consistent when compared to those produced by a TIG welder. Issues such as spatter, poor bead formation, and heat distortion can arise, especially on thinner materials or more complex welds.
• Quality Variation: The quality of the weld may vary based on the type of stick welder you are using and its compatibility with TIG welding tasks. For projects requiring precise and high-quality welds, a dedicated TIG welder would provide more consistent results.
