    Tomahawk 1538 LC105 Consumables FAQs

    Plain answers on the front-end wear parts of a hand-held air plasma torch: what each one does, how to tell it is worn and how to order the right ones.

    What parts make up the front end of a plasma torch and what does each do?icon-minus-redicon-plus-red

    Most hand-held air plasma torches use a stack of consumables. The electrode carries the current and is the starting point of the arc. The nozzle shapes, directs and squeezes the arc into a narrow jet. The gas distributor or swirl ring spins the gas around the electrode to centre the arc. The shield protects and cools the nozzle from molten spatter, and the retaining cap holds the stack on the torch head.

    Exact names, numbers of parts and the order they fit vary, so follow the torch manual or parts diagram for your torch.

    How can I tell when the electrode or nozzle is worn?icon-minus-redicon-plus-red

    The electrode has a small insert in its tip, and as it is used the insert erodes and forms a pit. The maker's manual gives the pit depth at which to change it, and the limit differs between torches, so do not rely on a number from elsewhere or on a set number of hours.

    A nozzle should have a round orifice with sharp edges. Change it if the orifice is nicked, oval or has rounded edges. A worn nozzle also shows in the cut: a wider kerf, a bevel on the edge, and a bevel that changes from one side to the other, which usually points to a failed nozzle.

    Should I change the electrode and nozzle together?icon-minus-redicon-plus-red

    Yes, treat them as a set. Plasma makers advise changing the nozzle and electrode together, because a worn part left in the stack can quickly damage a new one and spoil cut quality. Running an electrode past the end of its life is also one of the things that damages nozzles.

    The other parts last longer. The swirl ring, shield and retaining cap usually last through several electrode and nozzle changes, but look at them each time you change the set. Replace any that are cracked, damaged or clogged.

    Why must the consumables match the current and the job?icon-minus-redicon-plus-red

    Consumables are made for particular currents, materials and applications, and mixing them up is a common mistake. A nozzle that is not suited to the current you have set can overheat and wear quickly, and running at a current that is too high for the parts is a known cause of nozzle damage.

    Most torches use different consumable sets for cutting, gouging and other jobs, so the manual tells you which combination to fit for each process. Check the part numbers and ratings in the manual rather than guessing from how the part looks.
