Features: 1. Much smaller & lighter by comparison to the transformer welding machine; its medium frequency inverter transformer inside is much lighter than the traditional transformer; in total, its weight is only within a range from 1/5 to 1/10 of the weight of the transformer welding machine, and around 1/3 of the transformer welding machine in volume; 2. High efficiency and energy savings; due to a much smaller volume, the raw materials of copper and steel needed are much less consumption, and there is much less non-contribution energy consumption while current runs through; its power usage efficiency is up to 80 – 85%, its power factor is up to 0.93; and the energy consumption saving is up to 1/3 in total by comparison to the transformer welder. 3. Convenient to continuous adjustment of the welding current & voltage; capable of satisfying with the requirements of the different welding processes 4. Stable welding processes with much less spatters to assure a smooth and quality seam 5. Auto-Compensation-Function as to the power supply fluctuation, a strong adaptability of anti-power-supply fluctuation MIG180 ParameterInput Voltage(V)AC220V±15%Efficiency(%)80Frequency(HZ)50/60Arc IgnitionHigh-frequency ARCRated Input Power(KVA)11.3Power Factor0.73Output Current(A)50-180Insulation GradeFOutput Voltage Adjustment(V)23Housing protection GradeIP21Wire-feeding Speed(m/min)2.5-15Net Weight(kg)9Duty Cycle(%)60External Dimension (mm)371*153*232Type of Wire FeederBuilt-in Product Purchase GuideBase MaterialWelding methodPlate thickness(mm)Current Range(A)Applicable ModelCarbon SteelCO2/MAG0.8/0.850-180MIG180Low- Alloy SteelsStainless Steel
