Features: Rationale: Adapted powerful MOSFET to change the supply frequency of 50/60HZ to high frequency (up to 100KHZ), and then to come down the voltage as well as to change the AC current to DC current by the circuit, and eventually to turn out the powerful DC supply under the support of the PWM adjustment technology; in such an inverter design circuit, the weight and volume of main transformer comes down dramatically , and its efficiency is over 30% increased instead 1. Auto-Compensation-Function as to the power supply fluctuation, strong adaptability of anti-power-supply fluctuation and stable welding current 2. Over-Voltage, Over-Current , Over Heat Auto-Protection Functions 3. Excellent Arc Force Compensation Function 4. Reliable, Light and Small with High-Efficiency & High Energy Savings 5. Adaptable to the welding application in different kinds of acid or basic electrodes 6. Adaptable to the welding application on different kinds of low carbon steels, medium carbon steels and alloy-steels ARC160T ParameterInput Voltage(V)AC220V±15%No-load Loss(W)40Frequency(HZ)50/60Efficiency(%)80Rated Input current(A)32.7Power Factor0.73No-load Voltage(V)65Insulation GradeFOutput Current Range(A)10-160Housing protection GradeIP21Rated Output Voltage(V)26.4Net Weight(kg)8Duty Cycle(%)60Dimension (mm)375*155*232 Product Purchase GuideBase MaterialWelding methodPlate thickness(mm)Current Range(A)Applicable ModelCarbon SteelARC2.0-4.010-160ARC160TLow- Alloy SteelsStainless Steel
