Genuine Hypertherm Nozzle, Gouging, 100Amp. 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.
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. If you are unsure, our team can help you check.
Consumables are only one cause. The makers' troubleshooting guides point first to travel speed: too slow leaves thick dross along the bottom edge, while too fast leaves a small hard bead. Torch standoff height that is too high or too low and a cutting current that is wrong for the nozzle also cause dross.Adjust one setting at a time in small steps, using the cut chart in your manual. Also check that the parts are the right set for the current and are fitted correctly, and that your air supply is clean and dry.
