Inverter DC Pulsed Tungsten Arc Welder

HT160A/180A/200A
1.CHARACTERRISTICS AND APPLICATION
Inverter DC tungsten argon gas welding machine (HT160A/180A/200A) 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:
A. Moistureproof/dustproof/saltproof treatment, EMC and EMI
B. High inverter frequency, rapid dynamic respond, calm arc, good welding seam and nice welding performance.
C. Arc igniting is stable and operation is convenient by HF technique;
D. Perfect protection: with over-current and over-heat protection, slow startup of current
against shock.
E. One machine can be used in DC Arc welding, Tig Arc welding and Manual welding
F. Pulse frequency and pulse ration can be adjusted continuously and widely. Combat the pulsed switch and frequency range selecting, making the pulsed welding technology more advanced
G. Base current can adjusted between 10-90% of crest current
H. The indication function is complete, making the operation is more directly and more easily
I. Manual welding equipped with electrical thrust self-adjust circuit.
J. 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.
