Electrodes Life's Saver

  1. Use standard electrodes with ejector type, self-adjusting tube, water-cooled electrode holders wherever possible. Avoid special or irregular shapes for lowest cost.
  2. Use ample cold cooling water as close as practical to the welding contact surface, properly circulated at a minimum of 30-psi pressure, and supplied at a rate of at least 1-1/2 gallons per minute.
  3. Be sure to select the proper type and size of electrode, taking into consideration electrode pressure, contact area of electrode, gauge, and nature of material to be welded.
  4. Overloading as well as overheating shortens electrode life.
  5. Good welds depend upon properly maintained electrodes which assure an accurate surface contact. Keep tapers clean and dress electrode faces with lathe, emery Paper or fine file. Use castor oil or graphite grease to facilitate tip removal, and avoid application of insulators such as white lead, Teflon tape and other materials.
