Plasma cutting quality control: Cutting Current

Plasma cutting is widely used in various industrial fields. Because it has fast cutting speed, high cutting quality and wide range of cutting materials. 

It plays an important role in the field of material cutting and parts processing. Plasma cutting quality is affected by many factors, such as cutting process parameters, material, gas purity, etc.

Cutting Current

When the cutting current is lower than the standard value, bottom is extruded. Because the bottom of the workpiece is not completely melted and not easy to remove with slag. 

When the cutting current is higher than the standard value, the diameter of the plasma arc increases and the kerf becomes wider. 

At the same time, excess heat makes the edge of the kerf melt. It will become rough.
