What is the Lincoln TER80SB2-24 ER80S-B2 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.

What diameter is the Lincoln TER80SB2-24 ER80S-B2 available in, and how do I choose the right size?

TIG filler rod diameter selection: match the rod diameter approximately to the base metal thickness. 1/16 in (1.6 mm) for thin sheet, 3/32 in (2.4 mm) for medium gauge, 1/8 in (3.2 mm) for heavy plate. Using a rod that is too large requires excessive heat to melt the rod and can cause overheating of thin base metal.

What shielding gas should I use with the Lincoln TER80SB2-24 ER80S-B2?

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 Lincoln TER80SB2-24 ER80S-B2?

The Lincoln TER80SB2-24 ER80S-B2 carries AWS ER80S-B2 classification, confirming it meets the American Welding Society's chemical composition and mechanical property requirements for that filler metal category. The AWS classification appears on the rod tube label and verifies the rod's chemistry for code-compliance welding procedures (WPS/PQR).

How should I store the Lincoln TER80SB2-24 ER80S-B2 to maintain weld quality?

TIG filler rods are typically sold in 36 in lengths in 1 lb, 5 lb, 10 lb, and 25 lb tubes. Store rods in their original sealed tubes in a dry location. Stainless and nickel alloy rods are particularly moisture-sensitive — exposure to humidity can introduce hydrogen and cause porosity or cracking. Never leave opened rod tubes exposed to damp air.
