Hyaccess consumables extend the torch with an additional 7.6cm (3") reach when installed compared to standard consumables. The unique design allows for better visibility and accessibility for working on challenging cutting locations such as corners and channels. The improved visibility and access achieved eliminate the need for certain secondary operations or multiple cutting passes.
Questions buyers ask when choosing, fitting and looking after replacement consumables for this style of plasma cutting torch.
A typical plasma torch consumable stack has an electrode, a nozzle, a swirl ring, a retaining cap and usually a shield. The electrode carries the current and wears with every arc start. The nozzle shapes and constricts the arc. The swirl ring spins the gas around the electrode, and the retaining cap holds the parts together.The shield protects and cools the other parts, especially the nozzle, from molten spatter. Some torches combine several of these parts into a single cartridge, so check your torch manual for the exact layout.
Start with the torch and power source data plate and the maker's consumable chart in the manual. Consumables are made for a specific torch design, so a part that looks similar may not seat, seal or carry the current properly.Match the part to the amperage you will cut at. Low-amperage parts should not be used for high-amperage cutting, or the other way round, because the orifice size and cooling are designed for a particular current range. If the chart is unclear, our team can help you identify the part from the torch type.
Electrodes have a small insert at the tip that wears into a pit as you cut. Some pitting is normal, but once it reaches the maker's limit the arc can damage the copper body and the torch can be harmed quickly. Some makers set the limit by cutting current, so use the figure in your manual. Replace the nozzle at the same time as the electrode.Other warning signs are a wandering or unstable arc, hard starting, and needing to slow down to get through the metal.
Usually yes. The nozzle and electrode wear together and an old part can spoil the life and cut quality of a new one, so makers generally recommend changing them as a set.A nozzle should be replaced when the orifice is nicked, out of round or has rounded edges, or when the cut becomes angled, rough or covered in dross. Look at the orifice in good light. If the hole is no longer a clean circle, replace it rather than trying to clean it up.
