Thermal Dynamics 9-8215 is the electrode for the SL60 and SL100 1Torch plasma torches, used on Thermal Dynamics Cutmaster and Victor air plasma cutters (30 to 120 A). This is an aftermarket part made to the same number and fit.
Copper body with a hafnium insert at the tip, where the arc attaches. The SL60 and SL100 use one electrode for every current from 30 A to 120 A; it wears with every start, so change it together with the tip.
Check the number on your old part or in the torch manual before ordering: it should read 9-8215. Sold in packs of 10.

Routine changes
The electrode is the fastest wearing part in the torch. Change it when the hafnium insert has a pit deeper than about 1.6 mm (1/16 in), when the arc starts to wander or the cut bevels, and always change the nozzle at the same time.
Keeping cut quality
A worn electrode makes the arc harder to start and widens the kerf. Fresh electrode and nozzle pairs keep the cut square and the dross low.

Yes, it was made for the Thermal Dynamics SL60, and 1 more listed under compatible equipment. Check the old plasma electrode is marked 9-8215 or one of the cross references, because makers change parts between serial ranges.
On the Thermal Dynamics SL60, it depends on hours and working conditions. Follow the machine service schedule, and change it when it shows wear rather than waiting for it to fail.
Leaks, noise, loss of performance, or visible wear compared with a new part. If in doubt, measure it against the sizes in the specifications.
Keep it until the new one is fitted and running. It is the quickest way to compare sizes, connectors and mounting if anything looks different.
Match the part number on the old plasma electrode to Thermal Dynamics 9-8215 or a number in the cross reference table. If the number is worn off, compare the sizes in the specifications.
No. It is an aftermarket plasma electrode made to replace the Thermal Dynamics 9-8215. It is not made by the original manufacturer; the number only shows what it replaces.
