Professional-grade 5/32″ 2% thoriated tungsten electrodesengineered for high-amperage DC welding applications. These tungsten electrodes deliver superior arc initiation and stable arc characteristics for demanding steel and stainless steel fabrication work.

The 2% thorium oxide additive provides excellent electron emission properties, allowing for easy arc starting at lower voltages while maintaining consistent arc stability throughout extended welding sessions. The 5/32″ diameter makes these electrodes ideal for heavy-duty applications requiring higher amperage ranges.

Welding Application Notes

2% Thoriated tungstenis the traditional choice for DC applications, particularly effective for:

• Carbon Steel:200-350 amperes for structural welding and heavy fabrication
• Stainless Steel:175-300 amperes for pipe welding and pressure vessel work
• Nickel Alloys:150-275 amperes for aerospace and chemical processing applications
• Electrode Preparation:Grind to 15-20° included angle for optimal performance

Note: While thoriated tungsten offers excellent performance characteristics, consider 2% lanthanatedor 2% ceriated tungstenalternatives for equivalent performance with reduced radioactive content in accordance with modern safety practices.

Ideal for production welding environments, structural fabrication shops, and maintenance applications where consistent high-amperage DC welding performance is required. Compatible with all TIG torch configurations designed for 5/32″ tungsten electrodes.
