Description
TUNGSTEN CARBIDE TUBULAR ELECTRODE
Postalloy® 220HD contains increased levels of tungsten carbide compared to Postalloy® 219HD, with additional chrome and cobalt for toughness. The unique blend of Tungsten Carbide and Chrome provides a high polish in service to reduce the coefficient of friction. When protection against severe abrasion is needed, Postalloy® 220HD is an ideal choice.
• Easy out-of-position weldability with the 1/4" diameter
• Excellent AC or DC operation, even on a "buzz box"
• Low amperage and high metal recovery - no slag to chip. Postalloy® 220HD is over 90% efficient.
• High deposition rates - up to 3 times faster than ordinary electrodes
• Moisture resistant coating, even under severe weather or high humidity
