# Telwin Linear 630 HD Professional 550A MMA DC Rectified Welding Machine 230V/400V with Accessories - TEL-860002

The Telwin Linear 630 HD Professional MMA DC Rectified Welding Machine with Accessories (TEL-860002) is a top-tier heavy-duty transformer-based rectified welding machine delivering a steplessly adjustable DC welding current of 60–550A from a 230V/400V three-phase power supply. Rated at 500A at 35% duty cycle and 370A at 60% duty cycle, it supports rutile, basic, stainless steel, cast iron, and aluminium electrodes from 2mm to 8mm diameter. With fan cooling, optional gouging capability, and an IP22 protection rating, it is engineered for the most demanding heavy structural fabrication, shipbuilding, construction, civil engineering, pipeline, and mining welding applications. Key Features: 60–550A Stepless Current Adjustment — Wide stepless current range for precise control across the full spectrum of electrode sizes and material thicknesses from light fabrication to heavy structural welding. 500A Rated Output at 35% Duty Cycle — Exceptional peak output for the most demanding heavy-duty welding tasks, with 370A sustained at 60% duty cycle for extended high-current welding sessions. Rectified DC Welding Output — Transformer-based rectified DC output delivers stable, smooth arc performance superior to AC welding across all compatible electrode types. 2–8mm Electrode Compatibility — Supports the widest range of electrode diameters from 2mm to 8mm, including rutile, basic, stainless steel, cast iron, and aluminium types. Optional Gouging Capability — Compatible with an optional gouging kit for carbon arc gouging applications in heavy fabrication and maintenance environments. 230V/400V Three-Phase Power Supply — Three-phase input for stable, high-efficiency operation in professional workshop and heavy construction environments. Fan Cooling — Active fan cooling maintains safe operating temperatures during sustained high-current welding sessions. IP22 Protection Rating — Suitable for indoor workshop and sheltered heavy construction site environments. Supplied with Accessories — Includes accessories for immediate operational readiness in heavy-duty welding environments.
