What diameter is the Harris 4047 718 GTAW Aluminum Welding TIG Rod 3/32 10LB Box - 0071850 available in, and how do I choose the right size?

The Harris 4047 718 GTAW Aluminum Welding TIG Rod 3/32 10LB Box - 0071850 is available in 3/32 diameter. Rod diameter selection depends on the base metal thickness and the amperage being used: 1/16 in (1.6 mm) rods suit light gauge up to 3/16 in at 60–130A; 3/32 in (2.4 mm) rods cover 3/16 in–1/2 in material; 1/8 in (3.2 mm) rods are used for heavier sections at 130–250A+. As a general rule, rod diameter should be close to or slightly smaller than base metal thickness.

What shielding gas should I use with the Harris 4047 718 GTAW Aluminum Welding TIG Rod 3/32 10LB Box - 0071850?

TIG welding shielding gas selection: use pure argon (99.995% purity) for most TIG applications including steel, stainless, aluminum, and titanium. Helium additions (25–75% He/Ar mix) increase heat input and travel speed for heavy section work and aluminum welding where higher deposition is needed. Never use CO2 or mixed gases designed for MIG welding in TIG torches.

What is the AWS classification of the Harris 4047 718 GTAW Aluminum Welding TIG Rod 3/32 10LB Box - 0071850?

TIG filler rods carry an AWS classification (e.g., ER70S-2 for mild steel, ER308L for 304 stainless, ER4043 for aluminum) that specifies the chemical composition and mechanical properties of the deposited weld metal. Always verify the AWS class when writing or qualifying a Welding Procedure Specification (WPS) for code work.

Q: What is the Harris 4047 718 GTAW Aluminum Welding TIG Rod 3/32 10LB Box - 0071850 used for?

Aluminum TIG rod is used with AC TIG welding on aluminum base metals. ER4043 (aluminum-silicon alloy) is the most common general-purpose choice — it flows well, produces a bright finish, and is compatible with most aluminum alloys. ER5356 (aluminum-magnesium) provides higher tensile strength and is preferred for structural parts and applications that require post-weld anodizing.

Harris 4047 (718) Aluminum TIG (GTAW) Welding Rod 3/32 10# Box - 0071850

Overview

Harris 4047 718 Aluminum TIG GTAW Welding Rod 3/32 10LB Box - 0071850

4047 aluminum TIG (GTAW) welding and brazing alloy has a higher silicon content (11% to 13%) making it an ideal substitute for 4043 because it increases the silicon in the weld metal. Its lower melting point allows for excellent fluidity enabling it to be used as a brazing alloy on thin sections. It complies with ANSI/AWS A5.10 Class R/ER 4047 and ASME SFA 5.10.

Features

Aluminum welding and brazing alloy
Ideal replacement for 4043 to increase the silicon in the weld metal
