LN500W Synergic Double Pulse is an inverter technology gas welding machine that can perform MIG/MAG (MAG), MMA (covered electrode) and Argon (lift-TIG) welding with a single machine. Thanks to its synergic function, it can handle all kinds of additional wires, wire diameters and shielding. By using welding programs according to gas type, when any of the material thickness, wire speed or current values are selected, it selects the appropriate welding process by adjusting the output voltage.
