Best Tig Welder for Aluminum FAQ
What makes an AC/DC TIG welder essential for welding aluminum?
Aluminum welding requires alternating current (AC) because aluminum forms a thin, tough oxide layer that has a higher melting point than the base metal. AC current cycles between positive and negative polarity, with the negative cycle providing penetration and the positive cycle (the “cleaning action”) effectively blasting away this oxide layer, ensuring a clean, strong weld. DC (direct current) TIG is typically used for steel and other metals.
What is AC Balance and why is it important for aluminum?
AC Balance control allows you to adjust the ratio of electrode negative to electrode positive time during the AC cycle. Increasing the electrode positive percentage (higher AC Balance) provides more cleaning action to remove the aluminum oxide, which is great for dirty or oxidized aluminum. Decreasing it leads to more penetration and less cleaning, ideal for cleaner aluminum and better penetration on thicker sections, while also reducing heat input to the tungsten electrode.
How important is the Pulse feature for welding aluminum?
The Pulse feature cycles the welding current between a high peak current and a lower background current. For aluminum, this is very important for several reasons: it helps control the heat input, minimizing warpage on thinner materials; it allows for better penetration control; and it can produce a more aesthetically pleasing, coin-stack appearance in the weld bead. It’s particularly useful for precision work and out-of-position welding.
What’s the benefit of different AC waveforms (Square, Triangular) for aluminum?
Different AC waveforms offer distinct arc characteristics. Square Wave is the most common and provides a stable, focused arc with good cleaning action and penetration, making it excellent for general aluminum welding. Triangular Wave reduces the heat input more effectively than square wave, which is beneficial for welding very thin aluminum to minimize distortion and burn-through. Some machines also offer sine wave or soft square wave options, each with slightly different arc characteristics.
Do I need a foot pedal for TIG welding aluminum?
While not strictly required, a foot pedal is highly recommended for TIG welding, especially aluminum. It provides precise, instantaneous control over the amperage during the weld, allowing you to feather the current up and down as you start, move, and finish a bead. This level of control is invaluable for achieving high-quality, crater-free aluminum welds and managing heat input effectively.
What’s a good amperage range for welding various thicknesses of aluminum?
For hobbyist use, a 200A AC/DC TIG welder is often sufficient for most common aluminum thicknesses up to 3/16″ to 1/4″ at 220V. For thicker aluminum (e.g., 1/4″ to 3/8″ or more), a 250A or higher machine is preferable to ensure adequate penetration and heat capacity for sustained welding. When welding thinner aluminum (1/16″ or less), the ability to control low amperage and use features like pulse becomes crucial.
