1. Diode all wave rectifying add IGBT chopping to replace SCR rectifying,it’s improving the power factor;The DC part and inverter part into one cabinet,which reduce the waterway and circuit between the cabinets,which is effectively avoiding the electrical interference and reducing the installation time.
2. we adopt sub-resonance,no-welding transformer output mode and make resonance directly by tank resonance capacitor (low voltage) and inductor to achieve steel pipe welding power transmission by output lead.
3. Use sealed box and install overhead air conditioning.
