Telwin Nordika 3250 250A MMA AC Transformer Welding Machine 230V/400V – TEL-812012

The Telwin Nordika 3250 MMA AC Transformer Welding Machine (TEL-812012) is a robust transformer-based AC welding machine delivering a steplessly adjustable welding current of 70250A from a 230V single-phase or 400V two-phase power supply. Designed for general mild-steel fabrication, welding gates, railings, and steel frames, and construction and installation work, it supports rutile electrodes from 2mm to 5mm diameter. With built-in thermostatic protection, Class H insulation, and an IP21 protection rating, it is a dependable mid-range professional AC welding solution for workshops and construction sites.

Key Features:

• 70250A Stepless Current Adjustment Continuously adjustable welding current for precise control across a wider range of electrode sizes and material thicknesses than the Nordika 2160/2162 series.
• Dual-Voltage 230V/400V Input Operates from 230V single-phase or 400V two-phase power for flexibility across workshop, site, and construction power installations.
• 25mm Rutile Electrode Compatibility Supports rutile electrodes from 2mm to 5mm diameter for a wider range of mild-steel fabrication and structural welding applications.
• Thermostatic Protection Built-in thermostatic protection prevents overheating and protects the machine during extended welding sessions.
