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. Digital display, current & voltage preset function 4. Continuous adjustment function of the welding current & voltage with a sufficient wide adjustment range 5. Capable of forming a good seam shape in the opposite side while making a backing weld 6. Adapted an instant wire feeding circuit design, much more stable in wire feeding by comparison to the traditional instant voltage wire feeding mode, capable of achieving highly stable wire feeding within the full range of current adjustment 7. Highly stable during the welding process with soft & smooth melted drop transferring so as to assure a nice and smooth seam shape 8. Built-in a unique electronic inductance, capable of precisely control the short-cut melted drop transfer and the mixed transfer processes as well; capable of precisely changing the status of arc stiffness through adjusting the knob of electronic inductance to meet the different characteristic requirements according to the users’ different requirements Application Fields: * Light, medium steel structure, furniture and leisure items working shop * Steel structure assembly industry * Machinery manufacturing industry * Vehicle Repairs and Light Auto Manufacturing * Agriculture Tools Manufacturing etc TIG280G ParameterInput Voltage(V)AC380V±15%Efficiency(%)85Frequency(HZ)50/60Power Factor0.93Rated Input Current(A)9.9Insulation GradeFWire-feeding Speed(m/min)2.5-24Housing Protection GradeIP21Output Current(A)50-280Insulation GradeFOutput Voltage Adjustment(V)28Housing protection GradeIP21Duty Cycle(%)60Net Weight(kg)35Type of Wire FeederBuilt-inDimension (mm)595*275*520 Product Purchase GuideBase MaterialWelding methodWire Diameter(φ)Current Range(A)Applicable ModelCaron SteelCO2/MAG0.8/0.650-280280GLow-alloy SteelStainless Steel
