PURM-320A air plasma metal cutting device is designed to cut any metals and alloys with gage of up to 70 mm.
Unlike PURM-320 model its power supply has fine current adjustment system in the range of 70...280A with stabilization of +/- 2.5%, which allows to get high-quality cutting and use PURM-320A in thermal cutting machines, including those with numeric program control. Adjustment of cutting current is possible during working period.
The opportunity to extend the cable-hose toolkit up to 20 m considerably increases working zone of the device.
