What is red tungsten for?

What is red tungsten for?

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.

What do the colors on tungsten mean?

Color code and what it means 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 (sometimes also sold as white tungsten)

Is red tungsten able to be used on aluminum?

In summary, follow these three recommendations: 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.

What electrode is color coded red?

Tungsten electrodes
2. Red color code. Tungsten electrodes with a red color code contain 97,30 % tungsten and up to 2,20 % thorium. As this electrode operates below the melting temperature, it ensures much slower abrasion.

Is red tungsten safe?

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.

Is red tungsten for steel?

2% Thoriated Tungsten Electrodes – Red Tipped This type should be used on applications with DC current equipment with constant current from a transformer. Containing 1.7% to 2.2% thorium oxide, this radioactive tungsten electrode works well with mild steel, stainless steel and other non-corroding metals.

What are the different colors of tungsten for TIG welding?

Tungsten Tig Electrodes are colour coded, making them easy to identify.

• Gold = 1.5% Lanthanated Multi Type Tungsten Tig Electrode. Can be used pretty much any material in AC or DC output.
• Red = 2% Thoriated. Use for Tig Welding Mild Steel and Stainless Steel.
• White = Zirconiated.
• Grey = Ceriated.
• Green = Pure.

How do you choose a tungsten electrode?

The diameter of the balled end should not exceed 1.5 times the diameter of the electrode (for example, a 1/8-in. electrode should form a 3/16-in. diameter end), as having a larger sphere at the tip of the electrode can reduce arc stability and/or fall off and contaminate the weld.
