What diameter is the Harris ER80S-B2 Low Alloy Steel TIG Rod 5/32 x 36 in. x 10 lb. box - 80SB270 available in, and how do I choose the right size?

The Harris ER80S-B2 Low Alloy Steel TIG Rod 5/32 x 36 in. x 10 lb. box - 80SB270 is available in 5/32 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 ER80S-B2 Low Alloy Steel TIG Rod 5/32 x 36 in. x 10 lb. box - 80SB270?

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 ER80S-B2 Low Alloy Steel TIG Rod 5/32 x 36 in. x 10 lb. box - 80SB270?

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 ER80S-B2 Low Alloy Steel TIG Rod 5/32 x 36 in. x 10 lb. box - 80SB270 used for?

TIG (GTAW) filler rods are used in the gas tungsten arc welding process, where the welder manually feeds the rod into the weld pool while maintaining the arc with the torch. TIG welding produces the highest quality, lowest spatter welds and is the process of choice for precision work on stainless, aluminum, titanium, and exotic alloys.
