Our power supply has been especially developed for PTA welding. It generates a reproducible continuous currency and is based on inverter technology (high performance and reliability).

The system consists of the main power board and its control board (one time for pilot arc and one time for plasma arc). All boards are individually replaceable. This system configuration enables to reach a very high degree of reliability and simplifies maintenance. The power electronics contains an INVERTER operating at a high frequency with very low resonance period. The results are:

- Extremely even welding

- Easy starting

- Homogeneous droplet size

- Better penetration

- Smooth finish.
