Pro-source 22053003 Stick Welding Electrode 5/16 in Copper

Product Description

The PRO-SOURCE 22053003 is a copper stick welding electrode designed for use in shielded metal arc welding (SMAW) applications. Measuring 5/16 inches in diameter and 12 inches in length, this electrode suits jobs that require a larger-diameter rod for higher deposition rates or thicker base materials. The copper construction supports consistent arc characteristics and electrical conductivity throughout the weld pass. Welding professionals, fabricators, and maintenance technicians handling heavy-duty repair or fabrication work are the primary users of this electrode size.

This electrode is suited for industrial maintenance, structural repair, and fabrication environments where a 5/16-inch diameter rod is specified. The 12-inch length is a standard stick electrode dimension compatible with conventional electrode holders used in shop and field welding setups. Each package contains 50 electrodes, making it appropriate for production or recurring maintenance work where consistent supply of the same rod is needed.

Key Features

• 5/16 inch diameter for higher deposition and use on thicker base materials
• 12 inch standard length fits conventional electrode holders
• Copper material construction for consistent conductivity
• Sold in a 50-piece package quantity for production or maintenance use
• Lightweight individual rod weight supports extended use without operator fatigue

Compatibility

Designed as a standard-dimension stick welding electrode for use with conventional SMAW electrode holders that accept 5/16-inch diameter rods.

Installation Notes

Installation is performed by a qualified welder or welding technician following applicable AWS and workplace safety standards. Ensure the welding machine is set to the correct amperage range for a 5/16-inch electrode before striking an arc. Store electrodes in a dry environment to prevent moisture absorption, which can affect arc stability and weld quality. Inspect the electrode holder jaws for proper contact before use.
