. PRAKTIK 220 DIGITAL VRDPRAKTIK 220 is an inverter welding machine for MMA welding with direct current (DC) covered electrode and TIG welding with direct current (DC) with short-circuit arc ignition. Allows welding with rutile, alkaline, stainless steel and cast iron electrodes.Electronically controlled, smooth welding current control. Small size and weight make the device ideal for both workshop and field work.Clear digitaldisplay allows accurate adjustment of the device, ensures stable parameters and high quality welding.Voltage Reduction Device (VRD) function - reduces the idle state rest voltage on the electrode to a safe value. Provides electric shock safety when working in humid environments.The welder has functions to facilitate the process of MMA covered electrode welding:ARC FORCE: - facilitates the transfer of molten electrode droplets to the material being welded, preventing the arc from being extinguished when the electrode droplet comes into contact with the weld poolHOT START: - facilitates electrode ignition by delivering more welding current each time the arc is struck.ANTI STICK: anti-short-circuit - automatically shuts off the welding voltage if the electrode sticks to the material being welded, making it easier to peel the electrode off and preventing an accidental welding arc . . . . . BENEFITS OF THE DEVICE 220 A welding current Small dimensions of the device TIG LIFT welding capability HOT START - facilitates electrode ignition ARC FORCE VRD FUNCTION ANTI STICK -. anti-short-circuit function Ability to work with generator Ability to weld with electrodes as small as 5 mm Digital display Easy to use Case included. . .
