1. regular change consumable parts 1). Regular change oil. 2). Regular change consumable parts Continuous use finished and obsolete consumables affects the normal arcing in the plasma component leading to eventful torch failure. Poor cut quality is the obvious sign of worn-out parts. Replacement should be done when the nozzle oxide residues appear and there are signs of gouging in the inside and outside of the nozzle. Inspect the pitting of the electrode element to check whether the electrode is overused. If use oxygen gas, the pitting should not surpass a depth of 3/32 inches. Nitrogen and argon should be above 1/8 inches. Gas swirls with signs of cracks, burns and dirt particles should be changed promptly. 2. Use the right components Use different types of consumables which suit various types of cutting to keep component's life time and quality. 3. The torches can last long time. Proper cleaning, keep torch threads clean. The seating base should be contamination-free, make sure the consumables are kept in a clean place to prevent dust and dirt contamination. 4. Daily check gas and coolant flow Daily check the pressure of the gas and coolant. Cleanliness is vital, plasma gas must keep dry and clean. 5. Avoid continuous use of O-ring lubricant and anti spatter compounds Use the required quantity of O-ring lubricant to brighten up the O-ring. If plan to use antispatter compounds, ensure that shields are removed completely. Don't use grease and other lubricants. Torches doesn't need lubrication. Lubricant is good conductor of electricity which can damage the torch. Excess use compound can clog the swirl rings and attracts unwanted metal dust. These anomalies can cause arcing problem. 6. Do not hit hard parts with the torch. 7. Do not stretch the Arc Further extension of the arc more than the set limit will lead to the failure of the torch. Keep the edge starts are used instead of piercing starts. Whenever doing the edge, start the plasma arc with nozzle orifice facing the edge of material. Having a correct timing of the arc-off signal can prevent extensive stretching at the end of cutting. 8. Prevent torch collision To prevent torch collisions with material, the cutting system should be programmed to move around the material while making cutting. The collision can be mitigated by correcting the changing torch height sensor. 9. Keep correct standoff Standoff is determined by the thickness of materials. Keep the correct standoff can help the arc to flow. Too high or too low standoff level can damage material and torch. 10. Do routine Cleaning Clean the nozzle and electrode seating location. Use cotton swab or hydrogen peroxide to clean torch. <a href="https://www.honzhanmachines.com/Index/index/productdetail/HZ-P1530-Plasma-Cutting-Machine-for-Metal-Stainless-Carbon-Steel-Cutting.html" target="_blank"><img src="https://www.honzhanmachines.com/static/upload/20201016/HZ-P1530 Plasma Cutting Machine (2).jpg" style="border-width: 0px; border-style: solid; width: 700px; height: 389px;" title="image" /></a>
