    Powermax 45 Consumables FAQs

    Straight answers on choosing, fitting and looking after the torch consumables for a 45 amp class plasma cutter.

    Can I fit lower-current consumables in a plasma torch?icon-minus-redicon-plus-red

    Some torches are designed to accept the consumables of a smaller model in the same family, and parts rated for a lower current are often used when cutting thin metal at lower settings. That only works where the maker says the parts are compatible, so check the manual or consumable chart before mixing.

    Parts rated below the current you are actually cutting at will burn out quickly, and the reverse is also poor practice. Set the machine to a current that suits the consumables you have fitted, and use one matching set rather than odd parts from different current ratings.

    What are extended-reach consumables and when are they worth using?icon-minus-redicon-plus-red

    Extended-reach consumables are longer than standard parts and have a narrow tip. They let you get into corners, channels, close edges and flanges, and give a clearer view of the line you are cutting or gouging. They can save a grinding or gas-cutting step on awkward jobs.

    The trade-off is heat: longer, slimmer parts cool less well, especially on an air-cooled torch, so they are best kept for jobs that need the access. They are made for particular torch designs, so check that the part is listed for your torch and current before ordering.

    What is a gouging shield and nozzle used for?icon-minus-redicon-plus-red

    Gouging removes metal rather than cutting through it, for example taking out a weld or a bad joint. The nozzle has a larger opening than a cutting nozzle, which gives a wider, softer arc, and the torch is held at an angle to the work instead of upright. The shield is shaped to suit that technique and the spatter it throws.

    A gouging set is not a substitute for a cutting set. Fitting gouging parts for a straight cut gives a wide, rough kerf, so keep each set for its own job and check the maker's chart for the right parts for your current.

    What does an ohmic-sensing retaining cap do on a machine torch?icon-minus-redicon-plus-red

    On a mechanised torch, a height controller needs to know where the plate surface is. An ohmic-sensing cap is a retaining cap designed with a contact point for contact-based height sensing, so the controller can detect when the torch touches the plate and then set the pierce and cutting height from that point.

    It is only for machine setups that use that method of height finding. A hand cutting job does not need one, and an ordinary cap is the right part there. Check the maker's chart and your height control documentation to confirm which cap suits your torch and system before ordering.
