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.
Can you use GREY tungsten on 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.
What tungsten do I use 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. Remember that AC welding requires larger–diameter tungsten electrodes.Can purple tungsten be used on aluminum?
This rare earth tungsten offers excellent ignition characteristics and consistent welding properties. They are universal and suitable for all applications in the whole range of AC and DC welding of non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys.
Is E3 tungsten good for aluminum?
E3 Electrode Features and Benefits: Universal and suitable for all applications for DC and AC welding pf non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper, and magnesium alloys.
What is the purple tungsten for?
Tungsten electrodes – Purple is the new red For a long time, the red, thoriated tungsten electrodes were the first choice in TIG welding. In some places they are still considered the best solution for welding with direct current of high-alloy and stainless steels.
What is blue tungsten used for?
Blue tungsten is a good substitute for thorium oxide. It provides proper arc ignition and is more long-lasting than thoriated electrodes. It can be used for both AC and DC welding with both transformer and inverter power sources.Do you sharpen tungsten for aluminum?
How is Tungsten Balled for Aluminum Welding? … Sharpen one side of the pure-tungsten electrode to a spiky tip using a bench grinder. Put the sharpened electrode aside for 10 minutes, letting it cool down. Sharpen the other edge of the electrode to a point too, exactly like the other end.
Is Lanthanated tungsten good for aluminum?You can use blue lanthanated tungsten as an all-purpose option with a variety of metals, including nickel alloys, aluminum, cobalt, copper, carbon steels, and titanium.
Article first time published onWhat are GREY tungsten used for?
They are best used to weld carbon steel, stainless steel, nickel alloys, and titanium, and in some cases, it can replace 2 per cent thoriated electrodes.
What is yellow tungsten used for?
1.5% Lanthanated (Gold) The gold lanthanated tungsten electrodes contain less lanthanum than their blue counterparts and are best used in DC applications. They are best for welds with titanium alloys, copper alloys, nickel alloys, and non-corroding steel.
What is orange tungsten used for?
Thoriated tungsten is the most commonly used in the United States. This tungsten is used primarily in DC welding. It has a low work function and provides a high load and amperage capability.
What do the colors on tungsten mean?
Color code and what it means The main colors/varieties of TIG electrodes and their American Welding Society abbreviation are as follows: Green (EWP) = Pure Tungsten, Orange (EWCe-2) = 2% Ceriated, Red (EWTh-2) = 2% Thoriated, Gold (EWLa-1.5) = 1.5% Lanthanated, Brown (EWZr-1) = 1% Zirconiated.
What is green tungsten used for?
Green TIG Welding electrodes are pure Tungsten and are used for AC welding, often for aluminum and magnesium. They tend to be commonly used because they are inexpensive.

What color is E3 tungsten?
3/32 in E3 (purple) Tungsten for TIG Welding.
What is purple tungsten made of?
Rare Earth (Purple) Electrodes The innovative Rare Earth Blend tungsten electrode contains 98.34% tungsten, 1.5% lanthanum, 0.08% Zirconium, and 0.08% Yttrium. It is the perfect substitute for red thoriated electrodes.
What is E3 tungsten good for?
These tungsten electrodes are high-quality and ideal for use with both TIG and plasma arc welding applications. These tungsten electrodes are high-quality and ideal for use with both TIG and plasma arc welding applications.
What is red tungsten?
The EWTh-2 tungsten electrode is color-coded with a red band. It is known for its durability, ability to withstand high currents, and excellent arc starts. It is primarily welded using a negative polarity and direct current. It does not have great characteristics when welding with AC.
