For alleviating many troubles during plasma cutting, it is essential to take careful preparation, setup, and maintenance. Following are five things that would help you to avoid some of the common problems while handling plasma cutters.

Replace consumable parts regularly: it is much more effective to replace the consumables regularly than replacing the torch. Torch failure may happen if you are using severely worn consumables which can lead to uncontrolled arcing in the plasma chamber.

Assemble the torch properly: with correct care, torches would last for a long time. A properly assembled torch would ensure that the parts are in alignment and fit together snugly.

Use parts for the job correctly: check the operator’s manual that defines which consumables are appropriate for various types of cutting. If you use incorrect consumables, the life would be less and cut quality would be reduced.

Ensure coolant flow and gas accurately: it is important to check the flow and pressure of gas and coolant every day. For maintaining the cutting arc, constant gas pressure is important.

Avoid excessive application of lubricant: use just enough O-ring lubricant to put a shine and not more. Make sure to remove shields before putting antispatter compounds on them.
