Cap Electrodes

CenterLine's cap electrodes are manufactured using advanced cold-forming techniques to produce high quality, affordably priced, male and female caps. Cap production is closely monitored using SPC data tracking, for quick diagnostics, repair, and re-ordering which shortens downtime. An extensive range of styles and materials are available. 

Standard CenterLine electrode caps are available in: 

  • RWMA Class 1 (C15000; CuZr; zirconium-copper), creates less weld spatter and less energy to weld.  
  • RWMA Class 2 (C18150; CuCrZr; Chrome-Zirconium-Copper), the most economical cap and universal cap.  
  • RWMA Class 20 (C15760; CuAl2O3; GlidCop dispersion strengthened copper), longer weld life and works well on all steels.
  • Standard diameters of 1/2", 5/8"  3/4", 13mm, 16mm and 20mm.
  • RWMA standard nose styles: A, B, C, D, E, and F.
  • ISO standards in accordance with ISO 5121.
  • Non-standard styles and specifications (quoted upon request).
