1. The ornamental design for a plasma torch electrode, as shown and described.


FIG. 1 is a front perspective view of a plasma torch electrode showing our new design;

FIG. 2 is a front view thereof, the rear view, the right side view and the left side view being identical to FIG. 2;

FIG. 3 is a top plan view thereof;

FIG. 4 is a bottom plan view thereof;

FIG. 5 is a cross-sectional view taken along line 5-5 in FIG. 2; and,

FIG. 6 is a cross-sectional view showing the article installed in a plasma torch.

The features shown in even-length broken lines in the drawings depict environmental subject matter only and form no part of the claimed design. The dot-dashed lines shown in FIGS. 1 and 2 denote the boundary of the claim and form no part of the claimed design.
