Telwin LINEAR 500i XD - Inverter MMA Stick Electrode Welder (DC) 400A

The **Telwin LINEAR 500i XD** is an ultra-high-power DC inverter stick electrode (MMA) welding machine, ideal for industrial work and heavy-duty cycles. The **XD (eXtra Duty)** designation ensures a high Duty Cycle (400 A at 60%), supporting continuous use with electrodes up to **6 mm**. Featuring dual three-phase voltage (230V/400V), a digital display, and synergic settings, it is extremely versatile and is also prepared for **Gouging** applications.

Key Features

• Maximum Power: 400 A (at 400 V), ideal for continuous duty cycles (eXtra Duty).
• Dual Voltage: Operation on three-phase 230 V or 400 V mains supply.
• Usable Electrodes: Handles rutile, basic, stainless steel, cast iron, etc., electrodes with diameters from 1.6 mm up to **6 mm**.
• Smart Control: **Synergic** regulation of Arc Force and Hot Start based on the electrode type, along with the Anti-stick device.
• Display: Digital display shows the set welding current.
• Environmental Resistance: Tunnel ventilation system (dirt/dust resistant) preserves electronic components for increased durability. Robust, shock, and dust resistant (IP23).
• Additional Function: Prepared for **Gouging**.
