Inverter DC Pulsed Tungsten Arc Welder

1. CHARACTERRISTICS AND APPLICATION Inverter DC tungsten argon gas welding machine (HT160S/180S/200S) adopted MOSFET of TOSHIBA technology, applying PWM technique, can invert the working frequency AC 50Hz into the high frequency AC100KHZ, and reduces voltage through main transformer, insulating, two times rectify, then outputs DC power supply for welding. Characteristics: Rapid dynamic respond, calm arc, good welding seam and nice welding performance. Welding output has excellent performance, welding current is constant; Welding machine is reliable and stable by applying disconnected circuit. By HF igniting, operation is easy and arc ignition is stable. Easy operation, good performance welding process. Perfect protection: with over-current and over-heat protection, slow startup of current against shock. Smaller size, less weight, portable and good power saving. Applications: A: It can be used for welding all kinds of carbon steel, alloy steel, stainless steel, copper, titanium and their alloys. B: It can be widely used in machinery industry, oil and chemical industry, shipbuilding industry, vehicle industry, construction and decoration industry, etc.
