Thermal Dynamics 9-8243 is the shield deflector for the SL60 and SL100 1Torch plasma torches, used on Thermal Dynamics Cutmaster and Victor air plasma cutters (standoff cutting). This is an aftermarket part made to the same number and fit.
The deflector screws onto the front of the shield cup for standoff cutting, where the torch is held just above the plate. It shields the tip and cup from heat and spatter blown back from the cut.
Check the number on your old part or in the torch manual before ordering: it should read 9-8243. Sold in packs of 5.

Drag cutting
With a drag shield cap you can rest the torch on the plate and follow a line or template by hand. Replace the cap when its face is worn, burned or out of round.
Holding the stack together
The shield cup holds the start cartridge, tip and electrode in the torch head. Replace it when it is cracked or chipped or the thread is worn; a loose cup stops the torch firing, because the torch senses when the cup is not seated.

Yes, it was made for the Thermal Dynamics SL60, and 1 more listed under compatible equipment. Check the old plasma shield is marked 9-8243 or one of the cross references, because makers change parts between serial ranges.
On the Thermal Dynamics SL60, laser and plasma nozzles wear in days to weeks, depending on hours of arc or beam time, material and gas. Change it on condition, not by date.
An oval or nicked orifice, spatter stuck on the tip, more dross, a wider cut or bevel on one side, and height sensing errors.
Look at the orifice: if it is oval, nicked or has spatter stuck to it, the cut quality falls. Change it before it damages the parts behind it.
Centre the nozzle on the beam and recalibrate the height sensor. A new nozzle off centre cuts on one side only.
No. It is an aftermarket plasma shield made to replace the Thermal Dynamics 9-8243. It is not made by the original manufacturer; the number only shows what it replaces.
