What the nozzle is and who uses it
The Miller Enterprises 53N89 is an alumina welding nozzle supplied in a pack of 10. It is sized #15 with a 15/16 inch bore and a short-length profile. The nozzle fits A-125 series, A-80 series, W-200, W-250 series, A-150 auto, W-250 auto, A-150 series, A-200 series, W-350 series and W-410 torches. It is intended for welders who need replacement alumina cups for those compatible guns.
Compatibility check before ordering
Confirm that your torch model appears in the supported series list: A-125, A-80, W-200, W-250, A-150 auto, W-250 auto, A-150, A-200, W-350 or W-410. Verify that you require a #15 bore measuring 15/16 inch and a short-length design. The pack contains 10 nozzles; order additional packs if your project demands a larger quantity.
Heat resistance and consumable life
Alumina ceramic withstands the high temperatures found in TIG welding arcs and resists thermal shock during start-stop cycles. The material maintains its bore diameter under normal amperage loads for the listed torch series. Expect gradual wear from spatter adhesion and electrode contact; replace the nozzle when the bore erodes or the insulator cracks to preserve gas coverage.

Questions about this item
Does the pack of ten alumina nozzles include any additional collets or O-rings, or must those be purchased separately?
The package contains ten #15 alumina nozzles only; collets, O-rings and other consumables are sold separately.
Which nozzle size should I select for a W-250 series torch — is the #15 (15/16 in) the correct fit?
Yes, the #15 alumina nozzle is listed for use with the W-250 series as well as A-125, A-80, W-200, A-150 Auto, W-250 Auto, A-150, A-200, W-350 and W-410 torches.
How does the 15/16 inch bore affect shielding gas coverage on a W-350 series torch compared with smaller bores?
The larger 15/16 inch bore provides a wider gas envelope for heavy-amperage work on the W-350 series, while still fitting the torch’s standard nozzle thread.
