    Tomahawk 1025 LC65 Consumables FAQs

    Torch consumables for a hand-held plasma cutter: what each part does, how to spot wear and how to get the most from a set.

    What parts make up a plasma torch consumable set?icon-minus-redicon-plus-red

    A typical set has an electrode, a nozzle (the tip), and a shield cap, and some torches also use a swirl ring, a retaining cap and a spacer or drag guide. The electrode carries current and starts the arc, the nozzle focuses the arc and gas, and the shield cap protects the torch from sparks and molten metal. A swirl ring spins the gas, and the retaining cap holds the stack together.

    Designs vary, so check the parts diagram in your manual for exactly which pieces your torch uses before ordering.

    How do I tell when an electrode is worn?icon-minus-redicon-plus-red

    The electrode has an insert at its tip that wears into a small pit as you cut. Replace it when the pit becomes too deep, because running it further can damage the nozzle and torch. The pit depth limit depends on the maker, so use the figure in your manual.

    Cut quality is the other clue: if edges become rough, dross increases or the arc is hard to start, inspect the electrode and nozzle. Never refit a worn electrode just to use it up.

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

    Yes, that is the usual advice. A new electrode fitted behind a worn nozzle, or the reverse, tends to wear out quickly and gives poor cuts. Makers' manuals say to replace the nozzle at the same time as the electrode when the electrode is changed for wear, and some recommend changing the two as a set.

    Which of the two wears first depends on how you cut. Check the other parts at the same time, such as the swirl ring and retaining cap, for cracks, chips or blocked gas holes, and replace any that are damaged.

    What is the difference between drag cutting and cutting with a spacer?icon-minus-redicon-plus-red

    Some torches are designed so the front of the torch can rest on the plate and be dragged along the cut. Others need a fixed gap between nozzle and work, which a spacer or standoff guide helps you keep. A drag shield cap sits over the nozzle, so a nozzle must still be fitted beneath it.

    Which style you use depends on the torch design and the current setting, so follow your manual. Do not mix parts from different styles. If you are unsure which one suits your torch, check the data plate and manual, or ask our team.
