First Claim
Patent Images
1. An electrode for a plasma arc torch, the electrode comprising:
- an elongated electrode body having a first end and a second end; and
a shoulder having an enlarged diameter body integral with the electrode body, the shoulder having;
an imperforate face toward the first end; and
at least one rib extending aft of the face towards the second end of the electrode body, wherein the at least one rib has a varying height, thereby forming at least one groove in the shoulder body of varying depth.
