IGBT inverter DC arc welder

タイトルまたは説明

Applications and Features The central chip uses the current mode PWM keyer, the double closed loop negative feedback control, the electric current peak value inhibting ability is stonger. Complete machine output current fluctuation does not surpass 1A. Complete in both bridge inversion main circuit structure, ultra strong anti-overload capacity. Unique waits for an opportunity the active channel, when the iding the power source main circuit does not work, the welding machine life is higher, conserves energy.
