It can cause destructive arcing and burning within the torch. Too much lubrication can cause clogging and metal dust contamination in the torch, leading to uncontrolled arcing in the plasma chamber and ultimately torch failure. When applying O-ring lubricant, use just enough to put a shine on the O-ring. Cleanliness during torch assembly is very important and often neglected. When changing parts, keep consumables on a clean shop rag to prevent dirt or metal dust from contaminating the torch. This ensures good electrical contact and the correct flow of gas and coolant through the torch. If it is too high, the nozzle life will suffer.Īssemble the torch so parts are aligned correctly and fit together snugly. If the amperage is too low, the cut will be sloppy. The best cut quality and parts life is usually achieved when the amperage is set to 95 percent of the nozzle's rating. It is particularly important that you run parts at the correct amperage. Using incorrect consumables can lead to shortened parts life and reduced cut quality.
The operator's manual that came with your plasma system will tell you which consumables to use. Using the wrong parameters and parts for the jobĬonsumable selection depends on the material and thickness being cut, the amperage and plasma gas used and other arc cutting parameters.Often shields can be cleaned of metal spatter and reused. The same holds true for shields, which should only be replaced if they show signs of physical damage. Gas swirl rings should only be changed if a close examination reveals dirt or grease in the holes, or you see cracks, arc burns, or excessive wear. To tell if an electrode is spent, check the hafnium pit found in the very center and replace if too low. Are there gouges on the inside or outside of the nozzle? Is the orifice no longer round? If so, then it needs to be replaced. Rather than changing consumables after a set number of hours, an operator should look at how the consumables have worn. Once average life is established the operator will know when to check and or replace consumables preventing a catastrophic failure.Īt the complete opposite end of the spectrum are consumables that are discarded too early. Keep a record of the average parts life over time (in number of starts or arc-on time) and develop guidelines for expected parts life based on the amperage, material, and thickness you are cutting. However, the best way to judge the condition of your consumables is to periodically inspect your consumable stack-up when you notice that the cut quality is deteriorating. An experienced operator can tell consumables are worn by the sound coming from the torch, the color of the arc, or subtle changes in torch height. Using severely worn consumables can not only ruin a good piece of metal, it can cause expensive torch failures and unnecessary down time. Look in your used parts bucket and you will probably see consumables that have been run to failure. These savings will result in greater profits for your cutting operations and your company. Lowered overall costs.A good operator with well-maintained plasma arc cutting (PAC) equipment can save a shop hours of downtime and thousands of dollars in operating expenses.
