Cutting nozzles are precision pieces of equipment and if treated accordingly, they will provide months of
satisfactory operation. Treat them as you would any other expensive tool and consider the value of the product that they will produce if maintained in good working order. If treated poorly they will not only cost the value of their own replacement, but the cost of scrap and repair of undesirable product that they will produce.
