Electrode lifespan depends on material, current levels, and maintenance. Typically 50,000-200,000 welds for copper-chromium electrodes with proper dressing. Regular inspection for pitting, deformation, or contamination is recommended every 10,000 cycles.
Sticking typically results from insufficient force, incorrect alignment, contaminated surfaces, or excessive current. Ensure proper electrode dressing, clean workpiece surfaces, and verify machine parameters match material specifications.
Yes, electrodes can be refurbished through machining, re-plating, or tip replacement when wear is within 20% of original dimensions. Complete replacement is necessary when conductivity drops below 80% IACS or dimensional tolerance exceeds ±0.2 mm.
