What color is an EWTh-2 tungsten electrode, which has 2% Thoria added?

An EWTh-2 tungsten electrode, which contains 2% Thoria, is identified by its red color code. The addition of Thoria is used to enhance the electrode’s performance, particularly in terms of arc stability and longevity, making it suitable for welding applications involving materials like stainless steel and aluminum. In welding practices, color coding is critical as it allows welders to quickly identify the type of electrode they are working with, ensuring that they choose the appropriate one for their specific welding needs. The standardized color codes help maintain consistency across the industry, facilitating both safety and efficiency in welding operations.
