Thyristor Control DC Submerged Arc Welding Machine
1. Main circuit is thyristor rectifier circuit of double reverse-stars type with balanced reactance.
2. AC contactor is current pick-up, no-load, to reduce the impulse current.
3. Voltage fluctuation compensation function can supplies power system’s voltage fluctuation efficiently.
4. Exhaust fan type, no dead angle in wind tunnel
5. Multiple protective functions, high reliability.
6. Variety welding technology for submerged arc welding, manual electrode welding, carbon arc gouging, electro-slag welding.
