This thermal dynamics 9-8215 replacement electrode is for use with your SL60 or SL100 plasma 1 torch and is suitable for all thermal dynamics cut master series plasma cutters. The innovative, patented electrode self-locking mechanism eliminates the need for an installation tool and ensures that the electrode and tip will be in perfect alignment. Both the electrode and tip are stationary which results in a well-defined arc and precise cuts. This perfect alignment also means longer tip and electrode life, reducing operating costs.
