What diameter is the Harris 308LSi Stainless TIG GTAW Welding Rod 3/32 X 36 X 10# Box - 308ST50 available in, and how do I choose the right size?

The Harris 308LSi Stainless TIG GTAW Welding Rod 3/32 X 36 X 10# Box - 308ST50 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 308LSi Stainless TIG GTAW Welding Rod 3/32 X 36 X 10# Box - 308ST50?

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 308LSi Stainless TIG GTAW Welding Rod 3/32 X 36 X 10# Box - 308ST50?

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 308LSi Stainless TIG GTAW Welding Rod 3/32 X 36 X 10# Box - 308ST50 used for?

Stainless TIG rod is used for GTAW (TIG) welding of stainless steel base metals. Match the filler alloy to the base material: ER308L for 304/308 stainless, ER309L for dissimilar welds (stainless to carbon steel), ER316L for marine and chemical service, ER317L for higher corrosion resistance than 316L. Using the wrong filler can reduce corrosion resistance at the weld zone.
