Telwin Mastermig 275i Professional 250A Multiprocess MIG-MAG, MMA & TIG DC-Lift Inverter Welding Machine 400V - TEL-816196

The Telwin Mastermig 275i Professional Multiprocess MIG-MAG, MMA & TIG DC-Lift Inverter Welding Machine (TEL-816196) is a versatile 400V three-phase DC inverter welding system supporting MIG-MAG, Flux-Cored, MIG Brazing, MMA, and TIG DC-Lift processes with an adjustable current range of 20–250A. Rated at 250A at 30% duty cycle and 180A at 60% duty cycle, it features 2T and 4T MIG-MAG trigger modes, electronic reactance adjustment, a digital display, and Arc Force, Hot Start, and Anti-Stick functions for MMA welding. With 85% efficiency, a 0.72 power factor, and support for steel, stainless steel, aluminium, flux-cored, and brazing wire, it is a comprehensive professional welding solution for general fabrication, automotive bodywork, sheet-metal, stainless steel, and high-strength-steel welding.

Key Features:

• 5-in-1 Multiprocess Welding — Supports MIG-MAG, Flux-Cored, MIG Brazing, MMA, and TIG DC-Lift welding processes in a single professional inverter unit.
• 250A at 30% / 180A at 60% Duty Cycle — Flexible duty cycle ratings for both burst and sustained welding applications across all supported processes.
• 2T and 4T MIG-MAG Trigger Modes — Selectable 2T (standard) and 4T (latch) trigger modes for operator comfort during short tacks and extended seam welding.
• Electronic Reactance Adjustment — Electronic reactance control for fine-tuning arc characteristics and weld bead profile across different wire types and material thicknesses.
• TIG DC Lift-Arc Ignition — TIG welding with DC Lift-Arc ignition for clean, reliable arc starts without high-frequency interference.
• MMA Arc Force, Hot Start & Anti-Stick — Synergic arc control functions for stable MMA arc performance, easy electrode ignition, and electrode protection.
• Digital Display — Clear digital display for real-time monitoring of welding settings and values across all processes.
• Wide Wire Compatibility — Supports steel (0.6–1.2mm), stainless steel (0.8–1mm), aluminium (0.8–1mm), flux-cored (0.8–1.2mm), and brazing wire (0.8–1mm).
• MMA Electrode Compatibility — Supports MMA electrodes from 1.6mm to 5mm diameter.
• 85% Efficiency — High inverter efficiency reduces energy consumption in professional workshop environments.
• Wide Mains-Voltage Protection — -25% to +15% mains-voltage tolerance for stable performance on variable power supplies.
