- Thyristor (SCR) power controller/stabilizer
provides constant output power for consistent weld quality.
- Low-ripple filter network
minimises AC line harmonics to less than 1%, eliminating 'stitched' welds.
- Programmable logic controller (PLC)
provides complete control of welder operating sequence, monitors performance and gives full fault diagnosis.
- Automatic Speed/Power Control System
adjusts weld power for mill speed changes and minimises unwelded tube when mill is started or stopped.
- Heavy-duty main power transformer
provides reliable power output and long life.
- Compact, sealed power supply cabinet
may be located far away from the RF inverter to conserve space, without RF loss even over long distances. Removable doors and internal lighting enhance ease of maintenance.
