P-Cap

The P-Cap delivers twice the tip life with four times the number of welds, all without tip dressing.
The P-Cap uses a constant tip face geometry design for slow, consistent growth of the tip's welding surface.  It eliminates the need for tip dressing, and produces high quality welds on bare and coated steels. 

The P-Caps are available in a wide variety of sizes and shapes and manufactured in  both Nitrode® and Z-Trode® Materials. 
The P-Cap maintains a constant current density across the weld face under typical welding forces.  It does require 90-degree to 90-degree face contact and the use of steppers to maximize life.
