    Tomahawk 45 LC45 Consumables FAQs

    Plain answers on choosing, fitting and looking after the wearing parts of a hand-held plasma cutting torch.

    How do I work out which consumables fit my torch?icon-minus-redicon-plus-red

    Start with the torch itself, not the cutter. Check the torch model and the parts diagram or consumable chart in the manual, then match the part numbers on your old parts to the chart. This matters most on a second-hand machine, where the torch may not be the one the machine originally left the factory with.

    Parts are normally rated for a particular cutting current, and a part rated lower than the current you cut at will burn out quickly. Do not mix parts from different torch types because they look similar. If you are unsure, our team can help you match a part number.

    Which parts wear first, and how can I tell they are worn?icon-minus-redicon-plus-red

    The electrode and nozzle usually wear first. A falling cut quality is often the first sign: a wider kerf, more dross on the underside, a ragged edge or an arc that is hard to start. Look at the nozzle for an orifice that is enlarged, out of round, nicked or melted, and at the electrode for pitting or a burnt, rounded tip.

    If cut quality is poor and the electrode and nozzle have been changed, the swirl ring is the usual next thing to check. Running parts until they fail can damage the shield cap and the torch head as well, so inspect them regularly rather than waiting for a failure.

    Can I clean and reuse a shield cap?icon-minus-redicon-plus-red

    Often, yes. A shield cap that is undamaged can usually be cleaned of molten metal spatter and reused. Check the hole in the middle: if it is still round and the cap has no cracks, erosion or melted areas, it can go back on. If it is damaged, replace it.

    Use the cleaning tools the maker recommends, because the wrong tool can scratch or enlarge the parts. Clean the retaining cap and the seating faces too, so that the parts sit squarely and the gas cannot escape around them.

    What does the swirl ring do, and what should I check on it and the O-rings?icon-minus-redicon-plus-red

    The swirl ring spins the gas around the arc so that it is stable and cools the parts. Clogged or cracked gas holes make the cut worse and can shorten the life of the electrode and nozzle. A swirl ring that has been dropped can chip or crack, so check it by eye every time you change the electrode.

    Check O-rings for cuts, flattening and dryness. Use only a very light coat of the lubricant the maker recommends, never general grease, because too much lubricant can clog holes and cause arcing. The right replacement interval depends on the torch and how it is used.
