Recommended Amperage & Electrode Types for TIG Welding
TUNGSTEN TYPE
COMMENTS
1.5-2% Lanthanated (La)
Most versatile tungsten (best overall)
1.5-2% Ceriated (Ce)
Solid performance for most applications
1-2% Thoriated (Th)
Performance OK but hazardous
Pure
Ok but will ball up and not allow concentrated arc
