HyAccess consumables extend over 3 inches beyond standard consumables. The unique design allows for better visibility and accessibility for working on challenging cutting locations such as corners and channels.
Answers to common questions about the torch consumables and small parts used on a light-duty hand plasma cutter.
Worn electrodes shed molten material that is blown into the nozzle, so a nozzle fitted behind a worn electrode is usually damaged too. Makers' guidance is that when the electrode is changed for emitter wear, the nozzle should be changed at the same time.Fitting a fresh electrode behind a worn nozzle, or the other way round, often gives poor cut quality and shortens the life of the new part. Check the manual for how your torch handles this, and do not refit parts that you have already judged worn.
The electrode carries the current into the arc. The nozzle narrows and focuses the arc and gas. The swirl ring spins the gas around the electrode. The retaining cap holds the stack together in the torch head, and many torches also use a shield or cap at the front to take spatter and protect the nozzle.All of these wear or are damaged by heat to some degree, so they are called consumables. The exact parts and their order differ between torch designs, so use the parts diagram in your manual.
No. On many hand torches the arc starts the moment the trigger is pulled, and touching the consumables with power connected can cause an electric shock or burns. The maker's manual normally tells you to switch the power supply off, and to disconnect it from the mains supply for maintenance, before removing the cap.Some torches also have a torch-lock position, but follow the manual and do not rely on it alone. Parts can be very hot after cutting, so let them cool or wear suitable gloves. Your risk assessment and the maker's instructions set the full routine.
Several things shorten consumable life. The commonest are moisture or oil in the air supply, running the torch at a current above what the parts are rated for, and the wrong cutting height or travel speed. Poor earthing, a damaged nozzle or loose parts in the stack can also cause rapid wear, and so can many starts and pierces on thicker plate.Life varies with the work, so judge it against your own normal. If parts that usually last well suddenly fail early, check the air supply first, then the setup and the condition of the whole stack, and refer to the maker's manual.
