Description

Adopt double IGBT soft switch entire bridge inverter technology, uses the PWM Pulse Width Modulation(PWM), the closed-loop control system guarantees machine working stably, energy conservation and environmental protection, compared to traditional welder; It can save electricity above more than *0%. Ventilator intelligence control: According to the welding work time length, the frequency and the welding current size, automatically controls welder&#**9;s ventilator stops or keeping works, avoids unnecessary energy waste, simultaneously reduces the dust stack, enhances the ventilator electrical machinery life. Various protection performances: Good waterproofing, moisture-proof, dustproof processing. Rich protection functions: Secondary short circuit protection, superheat protection, primary overflow protection, over/owed presses protection and so on. Through guards against arc breaks return route, it can obtain the stable electric arc regardless of is solid core/drug core or other kind of combination, splashes lowly when welding. Adopt newly control system of striking arc, realized **0% smooth instant to strike arc. Automatic compensation function of long electronic cable, it can be used well when its electric cable lengthens to *0 meter. The product widely applies in ships, boiler, pressure vessel, petroleum, chemical industry, the electricity constructs, manufacturing industries, pipeline and so on.
