Pack of 25 (Part Number: 120927) Hypertherm Nozzles.
Straight answers to the questions people ask when buying plasma torch consumables in multi-packs.
Use the consumable chart in your torch or power source manual. It lists the part for each cutting current and application, such as handheld drag cutting, gouging or mechanised cutting. Match the part numbers to those shown for your torch, and make sure the part is rated for the current you cut at.Parts for one torch family generally do not fit another, even if they look similar. If you are unsure which part you need, check the data plate and manual, or ask our team.
In most plasma torches the nozzle and electrode wear fastest, because they create and constrict the arc. A drop in cut quality is usually the first sign. The shield mainly protects and cools the other parts from molten spatter, and the swirl ring and retaining caps usually wear more slowly.The order depends on the work, the number of pierces and the air quality, so keep notes of how long yours last. Check the swirl ring and caps for cracks, burns and blocked holes when you change the nozzle and electrode.
Yes, this is the usual advice. They wear together, and mismatched old and new parts tend to cut inconsistently. Maker guidance and trade guides say that when the electrode shows wear that needs replacing, the nozzle should be replaced with it.Packs of the individual parts make this easy to do every time. Look at the shield and swirl ring when you change them. A shield can often be cleaned of spatter and reused, and should be replaced if it is physically damaged.
Wipe parts with a clean, lint-free cloth and use clean air to clear debris, especially from the retaining cap. If you wash parts, use clean tap water; never use water from a cutting table.Some O-rings need a thin film of the lubricant the maker specifies, applied only if they look dry. Wipe off any excess, as too much can block gas flow. Fit parts in the correct order, tighten the electrode as the manual describes, and never refit worn parts.
