Thermal Dynamics 9-8237 is the max life shield cup body for the SL60 and SL100 1Torch plasma torches, used on Thermal Dynamics Cutmaster and Victor air plasma cutters (all currents). This is an aftermarket part made to the same number and fit.
The Max Life shield cup body screws onto the torch head and holds the start cartridge, tip and electrode in place. Its brass front takes the shield caps and deflectors, and it lasts longer than the standard cup.
Check the number on your old part or in the torch manual before ordering: it should read 9-8237.

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 9-8237 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.
Centre the nozzle on the beam and recalibrate the height sensor. A new nozzle off centre cuts on one side only.
On laser heads, a cracked ceramic ring or a loose nozzle breaks the capacitive height signal. Check that both are seated and clean.
No. It is an aftermarket plasma shield made to replace the Thermal Dynamics 9-8237. It is not made by the original manufacturer; the number only shows what it replaces.
