New concept
Water Hybrid Plasma Spray System WSP®-H 500

ITSC 2015

Our company exhibited Hybrid Plasma Torch WSP®-H 500 on the trade show INTERNATIONAL THERMAL SPRAY CONFERENCE on May 11 – 14, 2015 in Long Beach, California, USA.


General information

Long lasting cooperation of ProjectSoft HK a.s. and the Institute of Plasma Physics AS CR, v.v.i. (IPP) resulted in the creation of advanced hybrid plasma system for spraying - the WSP®-H 500.

ProjectSoft ( focuses mostly on delivering complete control systems including water and cooling systems for plasma spraying. IPP (, the research and development organization, has devoted more than 15 years to the research of thermal plasma with extreme values of temperature and to development of systems for plasma spraying. Our customers therefore benefit from joined know-how of both companies since we are not mere sellers but, in fact, we are the sole developers of the hybrid system!

The hybrid water-stabilized plasma torches have been developed on the basis of the research of thermal plasma arc systems performed at the Institute of Plasma Physics ASCR in recent years.

The WSP®-H 500 system is a high-power, high-throughput plasma spray system that utilizes water instead of gas as plasma medium. The system has been designed to extend the applications of plasma spraying to considerably larger surface areas and higher production volumes. In a side by side comparison, the WSP®-H 500 is dramatically more cost effective then lower throughput gas-stabilized plasma spray systems.
