Lincoln Electric KP4722-332 Tig Tungsten Electrode 3/32in

Product Description

The LINCOLN ELECTRIC KP4722-332 is a non-thoriated pure tungsten TIG welding electrode measuring 7 inches in overall length and 3/32 inches in diameter. Designed for gas tungsten arc welding (GTAW) applications, this electrode delivers a stable arc and consistent performance across a range of base metals. It is a standard consumable used by certified welders and fabricators in production, maintenance, and repair welding environments. The absence of thorium makes it a preferred choice where non-radioactive electrode materials are specified by shop policy or site safety requirements.

This electrode is suited for TIG welding on copper, aluminum, nickel, stainless steel, and carbon steel. It fits standard TIG torch collet bodies sized for 3/32-inch electrodes, making it a straightforward drop-in for most professional GTAW setups. Typical applications include structural fabrication, pipe welding, sheet metal work, and precision repair jobs where clean, controlled arc starts and bead profiles are required. Both AC and DC power sources are commonly used depending on base material and process requirements.

Key Features

• Non-thoriated pure tungsten construction — no radioactive material handling concerns
• 3/32-inch diameter fits standard collet bodies across most TIG torch brands
• 7-inch overall length provides full usable life through multiple re-grinds
• Compatible with copper, aluminum, nickel, stainless steel, and carbon steel base metals
• Suitable for both AC and DC GTAW processes depending on application

Compatibility

Compatible with copper, aluminum, nickel, stainless steel, and steel base materials. Fits standard TIG torch collet bodies designed for 3/32-inch tungsten electrodes. Designed as a replacement-grade tungsten electrode for professional GTAW applications.

Installation Notes

Installation and electrode preparation should be performed by a qualified welder or welding technician. Power down and de-energize the welding machine before inserting or replacing the electrode in the torch collet body. Grind the electrode tip to the appropriate geometry for the base material and polarity being used — always grind longitudinally along the electrode axis. Follow applicable AWS and shop safety standards for tungsten handling, storage, and disposal.
