Description of operation of the power sources and technical dates 19
Output Rectifier & AC Inverter
- Full bridge FRED rectifier
- Microprocessor AC current shaping
- Microprocessor controlled inversion
= Minimized voltage clamp
- Superimposition pulse generator
= Easy arc inversion and stable arc in AC welding
- Microprocessor triggered arc striking circuit
- Superimposition pulse + arc striking pulse
= Very easy arc striking even in worst operational contidions
(hard oxide on workpiece)
