Product details
Product details
The Telwin Mastermig 400 Professional MIG-MAG, Flux-Cored & Brazing Welding Machine (TEL-827004) is a high-output industrial 230V/400V three-phase DC welding system supporting MIG-MAG, Gas-Shielded Flux-Cored, and MIG Brazing processes with an adjustable current range of 50–400A. Delivering 400A at 25% duty cycle on 400V, 240A at 60% duty cycle, and 190A continuously at 100% duty cycle, it features both continuous and spot welding modes, a four-roller P-K wire-feed system, and support for steel (0.6–1.6mm), stainless steel (0.8–1.6mm), aluminium (0.8–1.2mm), flux-cored (0.8–1.2mm), and brazing wire (0.8–1.2mm). Engineered for general metal fabrication, automotive bodywork, sheet-metal, stainless steel, and high-strength-steel welding applications.
Key Features:
- 400A Maximum Output — Delivers 400A at 25% duty cycle on 400V and 400A at 20% duty cycle on 230V for high-throughput industrial MIG-MAG welding applications.
- 240A at 60% / 190A at 100% Duty Cycle — Sustained output ratings for both extended production welding and continuous duty industrial applications.
- MIG-MAG, Flux-Cored & MIG Brazing — Supports MIG-MAG, Gas-Shielded Flux-Cored, and MIG Brazing processes for versatility across steel, stainless steel, aluminium, and galvanised sheet metal.
- Continuous & Spot Welding Modes — Selectable continuous seam welding and spot welding modes for fabrication and bodywork applications.
- Four-Roller P-K Wire-Feed System — Robust four-roller P-K drive ensures consistent, reliable wire feeding across the full wire-speed range of 1.5–20m/min.
- Wide Wire Compatibility — Supports steel (0.6–1.6mm), stainless steel (0.8–1.6mm), aluminium (0.8–1.2mm), flux-cored (0.8–1.2mm), and brazing wire (0.8–1.2mm).
- 230V/400V Three-Phase Input — Wide voltage input with ±15% tolerance for compatibility with variable site and workshop power supplies.
- Large Wire-Reel Capacity — Accepts wire reels from 200mm to 300mm diameter for extended production runs without reel changes.
- Class H Insulation — High-grade insulation for safe, durable performance under demanding industrial welding conditions.
- IP22 Protection Rating — Suitable for indoor workshop and sheltered industrial environments.
