Telwin Mastermig 270/2 Professional 240A MIG-MAG & Brazing Welding Machine 230V/400V - TEL-821065

The Telwin Mastermig 270/2 Professional MIG-MAG & Brazing Welding Machine (TEL-821065) is a versatile 230V/400V three-phase DC MIG-MAG and MIG Brazing welding system delivering an adjustable welding current of 28–240A with both continuous and spot welding modes. Rated at 240A at 30% duty cycle, 160A at 60% duty cycle, and 130A continuously at 100% duty cycle, it supports steel (0.6–1.2mm), stainless steel (0.8–1mm), aluminium (0.8–1mm), and brazing wire (0.8–1mm) across a wire-speed range of 1.5–20m/min. With 10 voltage-adjustment steps, a 2+2 roller wire-feed system, and a 0.9 power factor, it is engineered for general metal fabrication, automotive bodywork, sheet-metal fabrication, stainless steel, and high-strength-steel welding applications.

Key Features:

• MIG-MAG & MIG Brazing — Supports both MIG-MAG welding and MIG Brazing for galvanised and coated sheet metal with minimal zinc burn-off, ideal for automotive bodywork and panel repairs.
• Continuous & Spot Welding Modes — Selectable continuous seam welding and spot welding modes for versatility across fabrication and bodywork applications.
• 28–240A Adjustable Welding Current — Wide current range for precise control from thin sheet metal through to heavier structural components.
• 240A at 30% / 160A at 60% / 130A at 100% — Flexible duty cycle ratings for both burst and sustained welding applications.
• 10 Voltage-Adjustment Steps — 10 selectable voltage steps for precise arc tuning across different wire types, diameters, and material thicknesses.
• Wide Wire Compatibility — Supports steel (0.6–1.2mm), stainless steel (0.8–1mm), aluminium (0.8–1mm), and brazing wire (0.8–1mm).
• 2+2 Roller Wire-Feed System — Four-roller drive (2+2 configuration) ensures consistent, reliable wire feeding across the full wire-speed range of 1.5–20m/min.
• Large Wire-Reel Capacity — Accepts wire reels from 200mm to 300mm diameter for extended production runs.
• 0.9 Power Factor — Near-unity power factor minimises reactive power draw for efficient mains power utilisation.
• 230V/400V Three-Phase Input — Wide voltage input with -25% to +15% tolerance for compatibility with variable site and workshop power supplies.
