Technical Advantages
- Soft-switching IGBT full-bridge inverter technology, double closed-loop current control (UC3846).
- Droplet transition waveform control technology (electronic inductance), freely adjustable arc shape, suitable for various welding requirements.
- The main transformer adopts ultra-fine crystal iron core, the inverter frequency up to 20KH.
- Passive power factor correction technology high power factor input voltage range 320V-450V.
- Arc starting and falling ball function, slow wire feeding for arc starting, high success rate of arc starting, less spatter, fast arc starting speed.
- High-power wire feeding system power supply, even in the case of large wire feeding resistance and long cable, it can feed wire stably.
- With self-locking/non-self-locking selection function, it is convenient for long-time welding operation.
- The split type wire feeder cable can be extended to 50m, which is suitable for large-scale movement.
- With over-current and over-heat protection function, full digital current and voltage display.
- Three-purpose machine for gas protection and manual welding of steam turbines (Model 500/630).
