Telwin Linear 430 HD Professional 360A MMA DC Rectified Welding Machine 230V/400V - TEL-860003

The Telwin Linear 430 HD Professional MMA DC Rectified Welding Machine (TEL-860003) is a heavy-duty transformer-based rectified welding machine delivering a continuously adjustable DC welding current of 80–360A from a 230V/400V three-phase power supply. Rated at 325A at 35% duty cycle and 240A at 60% duty cycle, it supports rutile, basic, stainless steel, cast iron, and aluminium electrodes from 2mm to 6mm diameter. With fan cooling, Class H insulation, and an IP22 protection rating, it is engineered for heavy structural-steel fabrication, shipbuilding, construction, civil engineering, and industrial workshop applications. Compatible with the Telwin MMA Welding Kit 801093 (sold separately) for a complete ready-to-weld setup.

Key Features:

• Rectified DC Welding Output — Transformer-based rectified DC output delivers stable, smooth arc performance for a wider range of electrode types and applications than AC welding.
• 80–360A Continuous Current Adjustment — Stepless continuous current adjustment for precise control across a wide range of electrode sizes and material thicknesses.
• 325A Rated Output at 35% Duty Cycle — High sustained output for demanding structural and heavy fabrication welding, with 240A at 60% duty cycle for extended welding sessions.
• Broad Electrode Compatibility — Supports rutile, basic, stainless steel, cast iron, and aluminium electrodes from 2mm to 6mm diameter for maximum welding versatility.
• 230V/400V Three-Phase Power Supply — Three-phase input for stable, high-efficiency operation in professional workshop and construction environments.
• Fan Cooling — Active fan cooling maintains safe operating temperatures during sustained high-current welding sessions.
• Class H Insulation — High-grade insulation for safe, durable performance under demanding welding conditions.
• IP22 Protection Rating — Suitable for indoor workshop and sheltered construction site environments.
• Compatible with Telwin MMA Welding Kit 801093 — Optional welding kit includes DALLAS 400 electrode holder, TOLEDO 400 work clamp, 4m electrode-holder cable (50mm²), 3m work-return cable (50mm²), AX50 cable connections, and slag-removal hammer and brush.
