PURM-400VA air plasma metal cutting device is the most powerful to be produced by our company. It is designed to cut out metals and alloys with gage of up to 100 mm.
Unlike PURM-400V model PURM-400VA device has water-cooled plasmatron which considerably increases cathode's life time.
PURM-400VA device has fine current adjustment system in the range of 70...350A with stabilization of +/- 2.5%, which allows to get high-quality cutting and use PURM-400VA in thermal cutting machines, including those with numeric program control. Adjustment of cutting current is possible during working period. PURM-400VA device is equipped with self-contained water-cooling system of plasmatron.
100% duty cycle applies to all range of gages.
