Causes and solutions of arc instability of plasma cutting machine

Causes and solutions of arc instability of plasma cutting machine:

 

1, the air pressure is too low or too high, adjust the air pressure;

2. Burn the electrode or nozzle in the torch, replace the electrode or nozzle;

3, input AC voltage is too low, adjust the input voltage

4, cutting ground and workpiece contact is not bad, re-clamping or replacement

5, cutting movement speed is too slow, adjust the cutting speed

6, spark discharge electrical appliances can not automatically break the arc, normal discharge 0.5s, ...

What are the differences between plasma,flame and laser cutting

一. Difference on conception

CNC Flame cutting machine: it is a type cutting equipment that use gas with oxygen or gasoline in metal materials with oxygen cut.
CNC plasma cutting machine: a type cutting methods that use high temperature plasma arc quantity of heat to make the metal parts of the work piece slit or partial melting (and evaporation), and borrow the plasma momentum ruled out a molten metal to form a incision.
Laser cutting machine: emit the laser from optical ...
