Genuine Hypertherm Nozzle 40Amp. PLEASE NOTE: Although the breakdown (quite rightly!) advises this item is normally packed in packets of 5, our price quoted is per item, not per packet.
Straight answers to the questions people ask when choosing and fitting replacement consumables and spare parts for a plasma torch.
The usual first sign is poorer cut quality: a wider cut, more dross on the underside, rough edges or hard starting. Then look at the parts. Maker guidance says to replace a nozzle that shows erosion, missing material, blocked gas holes or an off-round or enlarged centre hole, and a worn orifice is one of the first things to check when dross appears.When the electrode itself is worn, the maker advises replacing the electrode and nozzle together. Your manual gives the wear limits for your torch.
Usually not. The swirl ring is not worn by the arc in the same way, so it often lasts through several nozzle and electrode changes. Inspect it each time you change parts, and clear dirt from its gas holes with clean, dry air.Maker guidance says to replace a swirl ring that is chipped, cracked, has blocked gas holes or has damaged O-rings. Poor gas swirl affects cut quality, so do not keep using a damaged one. The replacement interval depends on the torch and how it is used, so follow your manual.
Consumables are made for particular current ranges. The nozzle orifice is sized for the current, and running a set well outside its range can burn it out quickly or spoil the cut. Gouging and fine-cutting nozzles also have different orifice sizes from standard cutting nozzles.If you cut across a wide range of currents you may need more than one set of consumables. Check the consumables chart in the maker's manual for the setting you use, and change sets when you change to a very different current.
Plasma consumables are specific to the torch and power source they were designed for, so match them to the torch model and cutting current shown in your manual. Check the markings on the torch and the data plate, and compare the part numbers on your existing nozzle, electrode and shield with the parts list.Parts that look alike can differ in orifice size, length or sealing faces, so do not rely on appearance alone.
