Pro-source 116-7E3 Tig Welding Rod 1/16 in 7 in 10-pack

Product Description

The PRO-SOURCE 116-7E3 is an E3 tungsten TIG welding electrode rod used in gas tungsten arc welding (GTAW) applications. Measuring 7 inches in length with a 1/16-inch diameter, this electrode is identified by its purple color code, which designates the E3 rare-earth tungsten classification. E3 electrodes are valued for their arc stability and long service life across a range of welding currents and base materials. This rod is sold in a pack of 10 and is a standard consumable stocked by welding shops, maintenance departments, and trade welders who require consistent, reliable electrode performance.

This electrode is suited for TIG welding on carbon steel, stainless steel, nickel alloys, and other metals where a stable, clean arc is required. The 1/16-inch diameter is commonly used for lower-amperage work and precision welds on thinner base material sections. Welding shops, fabrication facilities, and field service welders working with inverter-based or transformer-based TIG machines will find this a standard-fit electrode for bench and positional welding tasks.

Key Features

• E3 rare-earth tungsten classification with purple color code for quick identification
• 1/16-inch diameter suited for lower-amperage and fine-detail TIG welding
• 7-inch overall length provides standard reach for most TIG torch configurations
• Sold in a pack of 10 for shop stocking and regular consumable replenishment
• Compatible with both AC and DC TIG welding power sources

Compatibility

Designed as a standard E3 tungsten TIG welding electrode for use with GTAW torches accepting 1/16-inch diameter electrodes. Confirm collet and collet body sizing on the torch before installation.

Installation Notes

TIG electrode preparation and replacement should be performed by a qualified welder familiar with GTAW procedures. Ensure the welding machine is powered off and the torch is fully cooled before swapping electrodes. Grind or break the electrode tip to the appropriate geometry for the base material and polarity being used. Follow applicable AWS welding procedures and workplace safety standards when handling tungsten electrodes.
