If you are AC TIG welding aluminum for the first time we would suggest using a 2% ceriated in 3/32. Two solid options include Blue Demon or Weldcraft. Ceriated is the most popular choice due to the easy arc start at low amperages.

What color tungsten is for aluminum?

Pure Tungsten (Color Code: Green ) Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium.

What tungsten is best for aluminum?

Use a pure tungsten or zirconiated tungsten electrode when AC welding aluminum. Don’t use a 2 percent thoriated tungsten electrode. Make sure you use a tungsten electrode large enough in diameter to carry the welding current you plan to use.

Can I use GREY tungsten for aluminum?

Grey electrodes perform well in DC applications and are great for welding titanium, copper, magnesium, aluminum, and nickel alloys, as well as non-corroding and stainless steels.

Can you use blue tungsten for aluminum?

TIG Welding Tungsten Electrodes 2% Lanthanated (3/32″) The blue electrodes require low amperage, which is another plus to those using entry-level welding machines. These electrodes are indeed suitable, but they are also effective for many metals besides aluminum alloys.

What is the Green tungsten?

Pure Tungsten (Green) Electrodes They are made of 99.95% pure tungsten. Pure Tungsten (Green) Electrodes perform well in AC applications and are great for welding magnesium alloy and aluminum alloy.

What is purple tungsten used for?

Rare Earth (Purple) Electrodes It is the perfect substitute for red thoriated electrodes. They perform well in DC applications and are great for welding copper alloys, nickel alloys, titanium alloys, and stainless steel.

What type of tungsten has a gray color band?

EWCe-2 tungsten electrode is currently color-coded with a gray band, although in the past it was color-coded with an orange band. It is quite similar to EWLa-2 in that it has excellent current carrying ability, excellent arc starting ability, and can last through many different arc start and arc termination cycles.

What tungsten is radioactive?

The Thorium used in 2% thoriated tungsten is a radioactive element and therefore can be dangerous to the health of those exposed to it and to the environment.

What color tungsten is best for stainless?

What color Tungsten should be used for stainless steel? The thoriated red electrode is ideal for stainless steel welds. It provides the optimal heat generation, bead formation, and weld penetration to give smoother welds.
