Why the CNC plasma cutting machine can not cut through the steel?
First to check if it the problem of the machine or the plasma power supply.
The common problems of CNC plasma cutting machine are the following factors. No arc CNC plasma
cutting machine; the arc can not cut through the plate, or the arc easy broken through cutting etc.
When face the problem of no arc, first we need to check the electrode and nozzle of the cutting gun.
If it is damaged or replaced bad position. If it is in good condition, we have to check whether the
plasma power ventilation or air supply bad. We can judge the power supply problems or CNC cutting
machine problem through a short connecting power -the arc.
The plate can not be cut through by arc. Why? 1 reasons, a small current of CNC plasma power
machine can not cut the thick plate, 2, Grounding wires and cutting plate is not connected well. 3,
The air pressure is too small. 4, the gas for the plasma power supply owns high water content. 5,
The plasma cutting nozzle is too small.
