Telwin Linear 500I XD Professional 400A MMA DC Inverter Welding Machine with 600A Welding Kit, 230V/400V - TEL-816185

The Telwin Linear 500I XD Professional MMA DC Inverter Welding Machine with 600A Welding Kit (TEL-816185) is a high-output professional inverter welder delivering up to 400A at 60% duty cycle and 300A continuously at 100% duty cycle on 400V three-phase, with a wide mains-voltage tolerance of -25% to +15%. Its XD eXtra Duty construction is engineered for extended welding cycles in the most demanding heavy structural, shipbuilding, pipeline, and industrial applications. Supporting electrodes from 1.6mm to 6mm across rutile, basic, stainless steel, and cast iron types, it features Arc Force, Hot Start, Anti-Stick, a digital welding-current display, and optional gouging capability. Supplied complete with the Telwin MMA Welding Kit 801106 (DALLAS 600 electrode holder, TOLEDO 600 work clamp, 4m 70mm² electrode-holder cable, 3m 70mm² work-return cable, AX70 cable connections, and slag-removal tool).

Key Features:

• 400A at 60% Duty Cycle on 400V — Delivers 400A sustained output at 60% duty cycle and 300A continuously at 100% duty cycle on 400V for the most demanding extended welding applications.
• 300A at 60% Duty Cycle on 230V — Delivers 300A at 60% duty cycle and 210A continuously at 100% duty cycle on 230V for high-output single-phase-equivalent performance.
• XD eXtra Duty Construction — Engineered for extended welding cycles and sustained high-current output in heavy industrial, shipbuilding, and pipeline environments.
• Wide Mains-Voltage Tolerance — Operates reliably across -25% to +15% mains-voltage variation for stable performance on variable site power supplies.
