Hypertherm 420133 is the swirl ring listed for the Powermax30 AIR with the Air T30 hand torch. Arc Weld lists this exact item as a pack of one. Before ordering, match all three identifiers: the machine name, the torch name and the six-digit part number. A shopping result that says only “Powermax30 swirl ring” leaves out information that matters.
This guide answers a narrow purchasing question: how to order the individual 420133 ring without confusing it with another Powermax consumable or a multi-part replenishment kit. It is based on Hypertherm’s Powermax30 AIR Operator Manual 808840, Revision 5, April 2022, and Arc Weld’s exact product listing. Installation and operation must follow the manual applicable to your actual equipment.
The part and package to put on the order
- Manufacturer: Hypertherm.
- Part number: 420133.
- Component: swirl ring.
- Documented system and torch: Powermax30 AIR and Air T30 hand torch.
- Arc Weld selling unit: pack of one.
- Seller SKU: 420133.
Use the exact Arc Weld Hypertherm 420133 one-pack listing when those identifiers match your equipment and approved replacement requirement. Check the current listing for price, availability and delivery when placing the order. This article does not promise stock or a shipping date.
The seller identifies the product as Hypertherm. That identifies the listed brand; receiving inspection still needs to confirm the delivered packaging and part number. An aftermarket listing using “fits” or “replacement for” would be a different purchase requiring its own review. Do not treat a similar-looking ring as the same item.
Why the AIR designation matters
On page 66, Hypertherm’s manual states that the listed consumables are designed specifically for the Powermax30 AIR power supply and Air T30 hand torch, and cannot be used with another Powermax system or torch. Keep the full AIR designation on the purchase request. A shared brand or a similar number on a machine does not remove that restriction.
Read the equipment identification rather than relying on an old invoice or a remembered machine name. If the torch has been replaced, identify the installed torch too. If its identity is unclear, stop the parts order until the equipment record and manufacturer documentation agree. This guide does not establish compatibility for an undocumented conversion or another torch family.
WSP’s Powermax30 AIR machine support page and Air T30 torch lookup page can help organize that search. Use them as reference navigation, then confirm the actual part against the original Hypertherm document. A reference page alone does not approve a substitute.
A swirl ring order is separate from a nozzle or electrode order
The manufacturer’s consumables page also lists packages and kits for other components. It describes 420134 as a package of five nozzles, 420132 as a package of five electrodes, and 428350 as a kit containing two nozzles and two electrodes. Those quantities explain those particular order numbers. They should not be carried over to the 420133 ring listing.
Arc Weld’s 420133 product title expressly says pack of one. If a technician requests three rings, write the quantity in rings and confirm that the order is for three one-packs. If the request is actually for a full set of consumables, have the requester identify each needed component and quantity. Ordering one swirl ring should not be assumed to supply a nozzle, electrode, retaining cap or deflector.
This distinction helps purchasing without turning a buying guide into a service diagnosis. A list of neighboring part numbers does not mean every part needs replacement at the same time. The applicable inspection instructions and actual condition determine the service work; the purchase request should communicate the resulting parts requirement clearly.
A receiving checklist that stays with the equipment
- Match the invoice and package to Hypertherm 420133, not just the words “swirl ring.”
- Count the received rings against the ordered one-pack quantity.
- Keep the original packaging until the brand, part number and condition have been checked.
- Record the machine and installed torch for which the parts were purchased.
- Hold an unlabeled, damaged or conflicting item for clarification instead of putting it into the service bin as an approved replacement.
A short purchasing record can contain the equipment identifier, “Powermax30 AIR / Air T30,” part 420133, the number of one-packs requested and the manual revision used for the lookup. Keep any serial-specific or updated manufacturer instructions with that record. The cited manual provides the documented match here; it does not rule out later manufacturer revisions that apply to a particular unit.
Before any torch work
Hypertherm’s maintenance warning requires disconnecting electrical power before maintenance that removes consumables from the torch. Read the applicable manual and safety instructions before beginning. This article does not provide a disassembly sequence, adjustment setting or permission to test uncertain parts in an energized torch. Refer unresolved identification or service questions to a qualified technician or Hypertherm support.
