160 how to adjust the plasma cutting of four thick iron plates?
1. Contact the torch roller with the workpiece, and adjust the distance between the nozzle and the workpiece plane to 3 ~ 5 mm (set the "cutting thickness selection" switch to high grade when the main machine cuts).

2. Turn on the torch switch, ignite the plasma arc, cut through the workpiece, and move to the cutting direction at a uniform speed. Cutting speed is: on the premise of cutting through, it should be fast rather than slow. Too slow will affect the quality of incision and even break the arc.

3. After cutting, turn off the torch switch and the plasma arc will go out. At this time, compressed air will be sprayed out in time to cool the torch. After a few seconds, it automatically stopped spraying. Take off the cutting torch and complete the whole cutting process.
