Advanced IGBT inverter technology, Energy saving, stable output. With closed loop feedbacks, stable output voltage, and good resistance performance to voltage fluctuation. Electronic reactance design and inductance adjustment can control the arc for effective, less spark, deep bath, and beautiful welding seam. With 2T/4T, can reduce the fatigue of welder. Finishing welding protection, the welding will fill the crane by itself while finishing welding makes the seam look wonderful. External adjustment of voltage & current of ending current, ensure good welding performance. O.C. & O.H. Hard work welding / MIG welding, 2T/4T function, Hardwork welding preset current, Preset voltage of MIG welding, Meet the requirements of long-time working. Loop feedback control, stability Output voltage, mainly used in steel, the performance of the welding machine was improved significantly. Soft inductance / hard regulation, Meet different welding requirements.
