• Manufacturer:CK
• Part Number:T187GL2

Welding Performance Notes

2% Lanthanated tungsten electrodesare versatile performers suitable for both AC and DC welding. For DC applications, these electrodes handle 150-250 amps effectively with proper preparation. When welding aluminum on AC current, 2% lanthanated tungsten provides excellent arc initiation and maintains a stable, focused arc. The lanthanum oxide additive extends electrode life compared to pure tungsten while delivering superior performance to thoriated alternatives without radioactive concerns.

Amperage Guidelines:

• DC Welding:150-250 amps (depending on joint configuration and material thickness)
• AC Aluminum:125-200 amps with appropriate balance control
• Tip Preparation:Sharp point for DC, balled end for AC aluminum applications

Ideal for professional welders working with stainless steel, mild steel, and aluminum applications requiring consistent arc characteristics and extended electrode life. Compatible with standard TIG torch collet systems accepting 1/8″ diameter electrodes.
