The Jasic Arc 400 MMA welding inverter is equipped with the latest IGBT technology and a digital ammeter. This technologically advanced inverter is extremely user-friendly and offers reliable and constant arc performance. The Arc 400 also offers lift TIG functionality, making it an ideal choice for industrial applications. The VRD (Voltage Reduction Device) device is used to lower the output voltage to a safe level of 9 V when the welding machine is switched on but not ready for welding. This ensures the safety of the operator, who can safely come into contact with the electrode as long as the welding work has not been resumed.
