Xtrweld WTE3040 E3 Purple Tungsten Electrode 0.040 in 10-pack

Product Description

The XTRWELD WTE3040 is a ground tungsten electrode in the E3 classification, identified by its purple color code. It measures 0.040 inches in diameter and 7 inches in length, and is sold in a 10-piece pack. E3 tungsten electrodes are designed for TIG (GTAW) welding applications, offering stable arc characteristics across a range of base metals and current types. This electrode meets AWS A5.12 specification requirements. It is used by certified welders and welding professionals in fabrication, maintenance, and repair environments where precise, clean arc starts are required.

The WTE3040 is suited for TIG welding on materials including stainless steel, carbon steel, and nickel alloys in both shop and field environments. The ground finish on the electrode surface supports consistent arc initiation. The small 0.040-inch diameter makes this electrode appropriate for thin-gauge material welding where fine heat control is critical. Welding contractors, pipe welders, and precision fabricators working with lower amperage ranges will find this diameter range appropriate for their applications.

Key Features

• E3 classification with purple color code for easy identification
• Ground finish for consistent arc starts and electrode performance
• 0.040-inch diameter suited for thin-gauge TIG welding work
• 7-inch length providing standard compatibility with common TIG torch collets
• Meets AWS A5.12 specification
• Sold as a 10-piece pack

Compatibility

Designed as an OEM-style replacement or standard consumable for TIG welding torches that accept 0.040-inch tungsten electrodes with a 7-inch length.

Installation Notes

Tungsten electrode installation and replacement should be performed by a qualified welder or welding technician. Always power down the welding machine and allow it to fully de-energize before accessing the torch head or replacing the electrode. Ensure the collet and collet body are sized for 0.040-inch tungsten before inserting the electrode. Follow applicable AWS and shop safety procedures when preparing and grinding tungsten electrodes.
