Telwin Quality 280 Professional 230A AC / 160A DC MMA Transformer Welding Machine 230V/400V - TEL-855012

The Telwin Quality 280 Professional AC/DC MMA Transformer Welding Machine (TEL-855012) is a versatile transformer-based welding machine offering selectable alternating-current and direct-current welding output from a 230V single-phase or 400V two-phase power supply. In AC mode it delivers a steplessly adjustable current of 45–230A (rated 220A at 10% duty cycle, 90A at 60%), while in DC mode it delivers 25–160A (rated 150A at 15% duty cycle, 80A at 60%). Supporting rutile, basic, stainless steel, and cast iron electrodes from 1.6mm to 5mm (AC) and 1.6mm to 4mm (DC), it is fan-cooled with thermostatic protection and an IP22 rating — making it a professional and versatile welding solution for general fabrication, construction, workshop repairs, and agricultural equipment maintenance.

Key Features:

• Selectable AC & DC Welding Output — Switch between alternating-current and direct-current welding to match electrode type, material, and application requirements.
• 45–230A AC / 25–160A DC Stepless Adjustment — Wide, continuously adjustable current ranges in both AC and DC modes for precise control across all supported electrode sizes and material thicknesses.
• Broad Electrode Compatibility — Supports rutile, basic, stainless steel, and cast iron electrodes from 1.6mm to 5mm (AC) and 1.6mm to 4mm (DC) for maximum welding versatility.
• Dual-Voltage 230V/400V Input — Operates from 230V single-phase or 400V two-phase power for flexibility across workshop, site, and agricultural power installations.
• Fan Cooling — Active fan cooling enables more sustained welding operation and faster thermal recovery during extended welding sessions.
• Thermostatic Protection — Built-in thermostatic protection prevents overheating and protects the machine during demanding use.
• IP22 Protection Rating — Suitable for indoor workshop and sheltered construction and agricultural site environments.
