Telwin SUPERIOR 400 CE VRD - Multi-Process Inverter Welder 400A

The **Telwin SUPERIOR 400 CE VRD** is an industrial-grade multi-process inverter welding machine with a maximum output of **400 A**. Ideal for heavy-duty applications, it supports MMA stick electrode, TIG-LIFT in direct current (DC), and the **Gouging** function (with carbon electrodes). It is specifically engineered for use with **cellulosic electrodes** and handles diameters up to **8 mm**. The system includes the **VRD (Voltage Reduction Device)** safety feature, **MMA PULSE** mode, and a clear **LCD display** for parameter visualization.

Multi-Process and Safety Features

• Processes: MMA (Stick Electrode), DC TIG-LIFT (Scratch Start), and **Gouging** (with carbon electrodes).
• Safety: Equipped with the **VRD (Voltage Reduction Device)** for maximum safety in damp environments.
• MMA Mode: Features both direct current (DC) and **Pulsed DC (MMA PULSE)** operation for enhanced control.
• Electrode Capability: Excellent for **cellulosic electrodes**; handles rutile, basic, stainless steel, cast iron, and aluminum up to **8 mm**.
• Advanced Control: Automatic adjustment of Arc Force and Hot Start; Anti-stick protection.
• Design: Robust and compact (IP23). Dedicated tunnel ventilation system protects electronic components from dirt and dust.
