Cathode angle is 90deg. This is unusual angle for stable arc ignition. The temperature increase of the top point is insufficient, because of less effect of joule heating passing through in the electrode. Cleaning action in helium shield is strong, however it is less compared to that for sharp angle.

Cathode angle is 90deg. This is unusual angle for stable arc ignition. The temperature increase of the top point is insufficient, because of less effect of joule heating passing through in the electrode. However, cleaning action is much less compared to that for sharp angle.
