Welding Electrodes

Manual coated electrodes have exceptional welder appeal producing clean, well-defined, defect free beads. Unique features include:

  • Unique formulated flux - can be used as a multi-positional electrode
  • Excellent slag detachment
  • Low hydrogen, oxygen and nitrogen content in weld metal help develop mechanical properties

Applicable Processes

  • Manual Electric Arc Welding

Applicable Alloy Families 

Kennametal Stellite™ manufactures rutile, all directional electrodes in the following diameters.
