آلة لحام بعاكس رقمي متعدد الألوان

Crown Inverter DC MMA welding machine is ideal for light and medium-duty applications. Small and compact size with light weight and portability that makes it a great advantage for the welder. MMA welding technology: shielded metal arc welding / manual metal arc welding. IGBT technology: insulated bipolar force bipolar transistor Temperature protection:Automatically shuts off the power tool in case of overheating. VRD voltage reduction device: Enhances the idle voltage reduction function. The safety of performance welding work. Current control allows the current intensity to be changed, depending on the thickness of the metal, being cut. Easy start: Easy start function (increased idle operating voltage) Facilitates the ignition of the welding arc. Welding current meter displays the selected welding current.
