Best Tig Welder: Frequently Asked Questions

Q1: What does AC/DC mean for a TIG welder, and why is it important?

A1: AC/DC refers to the type of current the welder can produce. DC (Direct Current) is used for welding ferrous metals like mild steel and stainless steel, providing deep penetration. AC (Alternating Current) is essential for welding aluminum and magnesium. AC current helps to clean the aluminum oxide layer on the surface, making it possible to achieve strong, clean welds. If you plan to weld aluminum, an AC/DC TIG welder is a must-have.

Q2: What is “Pulse TIG” and how does it help my welding?

A2: Pulse TIG is a feature that rapidly switches the welding current between a high peak current and a lower background current. This pulsing action helps to control heat input, preventing burn-through on thin materials and reducing distortion. It also creates a distinct, stacked-dime appearance and improves arc stability, making it easier to achieve precise and aesthetically pleasing welds, especially for beginners working with stainless steel or thinner metals.

Q3: Do I really need a foot pedal with my TIG welder?

A3: While not strictly necessary for every TIG welding scenario, a foot pedal offers precise, on-the-fly current control, similar to a gas pedal in a car. This allows you to gradually increase or decrease the amperage during a weld, which is crucial for managing the weld pool, filling craters, and achieving clean starts and stops. Many experienced TIG welders find a foot pedal indispensable for achieving high-quality, controlled welds, particularly on critical or intricate work.

Q4: Can a 200-amp TIG welder weld thick aluminum?

A4: A 200-amp AC/DC TIG welder is generally capable of welding aluminum up to about 1/4 inch (6mm) thick effectively, and sometimes even 3/8 inch (9.5mm) with proper technique and joint preparation. For much thicker aluminum (e.g., 1/2 inch or more), you might start to push the limits of a 200-amp machine, and a higher amperage TIG welder like a 225A or 250A unit would provide more comfortable and consistent results.

Q5: What’s the difference between HF (High-Frequency) Start and Lift TIG Start?

A5: Both are methods for initiating the TIG arc. HF Start creates a spark between the tungsten electrode and the workpiece without physical contact, minimizing tungsten contamination and providing a very clean start. Lift TIG Start requires you to lightly touch the tungsten to the workpiece and then “lift” it away; the machine then senses this contact and initiates the arc. While Lift TIG is often found on simpler or more portable machines, HF Start is generally preferred for its cleaner and more reliable arc ignition, especially in sensitive applications.

Q6: What does “Square Wave” mean in the context of AC TIG welding for aluminum?

A6: Square Wave refers to the waveform of the AC current in a TIG welder. Traditional AC waveforms were sinusoidal, making arc stability and cleaning action challenging. Square Wave technology rapidly switches between positive and negative polarities, providing a very stable arc, efficient cleaning of aluminum oxide, and excellent penetration control. This results in cleaner, more precise aluminum welds with a tighter arc cone, making it a critical feature for effective aluminum TIG welding. Some advanced machines also offer triangular or other custom waveforms for even finer control.
