Frequently Asked Questions
What are tungsten electrodes used for in TIG welding?
Tungsten electrodes carry the welding arc in TIG (GTAW) welding. The electrode you choose affects arc stability, penetration, and weld cleanliness, especially on aluminum versus steel.
Which tungsten color should I choose: red, blue, gold, or green?
Red (2% thoriated) is the classic all-round choice for steel and stainless. Blue and gold (rare-earth mixes) offer easy arc starting and work well on both DC steel and AC aluminum. Green (pure tungsten) is a budget option mainly for AC aluminum on older machines.
What size tungsten electrode do I need?
For most hobby and light fabrication work on 1-3 mm material, a 1.6 mm (1/16 in) electrode is the sweet spot. Use 2.4 mm (3/32 in) for higher amperage or thicker material.
How do I grind a tungsten electrode correctly?
Grind lengthwise along the electrode, never crosswise, using a dedicated wheel. A straight, lengthwise grind keeps the arc focused and prevents wandering. For AC aluminum welding, a balled tip is formed naturally by the arc.
Do tungsten electrodes work with DC and AC machines?
Yes. DCEN with ceriated or lanthanated tungsten covers steel and stainless, while AC with pure or zirconiated tungsten is used for aluminum. Always match the electrode family to your machine output.
