PURM-320VA air plasma metal cutting device is designed to cut any metals and alloys with gage of up to 70 mm.
Unlike PURM-320A model PURM-320VA device has water-cooled plasmatron which considerably increases cathode's life time.
PURM-320VA device 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-320VA in thermal cutting machines, including those with numeric program control. Adjustment of cutting current is possible during working period. PURM-320VA device is equipped with self-contained water-cooling system of plasmatron.
100% duty cycle applies to all range of gages.
