Telwin Superior 400 CE VRD Professional 350A MMA, TIG DC-Lift & Gouging Inverter Welding Machine 230V/400V with 400A MMA Kit - TEL-816034

The Telwin Superior 400 CE VRD Professional MMA, TIG DC-Lift & Gouging Inverter Welding Machine with 400A MMA Kit (TEL-816034) is a high-output 230V/400V three-phase DC multiprocess inverter welder supporting MMA, TIG DC-Lift, and Carbon-Arc Gouging, with optional MIG-MAG and Flux-Cored capability via additional equipment. Rated at 330A at 35% duty cycle on 400V and 250A at 35% duty cycle on 230V, it delivers 230A at 60% on 400V and 170A at 60% on 230V. With adjustable Arc Force and Hot Start, Anti-Stick, VRD safety, remote-control connection, alarm memory for the last 10 alarms, and support for cellulosic, rutile, basic, stainless steel, cast iron, and aluminium-coated electrodes from 1.6mm to 6mm, it is supplied complete with the Telwin 400A MMA Welding Kit (801093) for immediate professional use.

Key Features:

• MMA, TIG DC-Lift & Carbon-Arc Gouging — Three-process capability in a single unit, with optional MIG-MAG and Flux-Cored welding via additional equipment for maximum process versatility.
• 330A at 35% Duty Cycle on 400V — High rated output with 230A at 60% duty cycle on 400V for sustained professional welding and gouging sessions.
• 10–350A on 400V / 10–300A on 230V — Wide adjustable current range for precise control from thin sheet metal through to heavy structural and pipeline components.
• VRD Voltage Reduction Device — Reduces no-load voltage between welds for enhanced operator safety in confined, damp, or pipeline environments.
• Cellulosic Electrode Support — Compatible with cellulosic electrodes for pipeline and vertical-down welding applications.
• Broad Electrode Compatibility — Supports cellulosic, rutile, basic, stainless steel, cast iron, and aluminium-coated electrodes from 1.6mm to 6mm.
• Adjustable Arc Force & Hot Start — Fine-tunable arc control functions for optimised arc stability and electrode ignition across all supported electrode types.
• Alarm Memory (Last 10 Alarms) — Stores the last 10 machine alarms for fault diagnosis and maintenance tracking.
• Remote-Control Connection — Remote control socket for convenient current adjustment from the welding position.
• 86% Efficiency & 0.9 Power Factor — High efficiency and near-unity power factor minimise energy consumption and reactive power draw.
• Supplied with 400A MMA Welding Kit (801093) — Complete ready-to-weld setup included.
