Telwin Eurarc 422 ACX Professional 320A MMA AC Welding Machine with Welding Kit, 230V/400V - TEL-858013

The Telwin Eurarc 422 ACX Professional MMA AC Welding Machine with Welding Kit (TEL-858013) is a heavy-duty transformer-based AC welding machine delivering a steplessly adjustable welding current of 70–350A from a 230V single-phase or 400V two-phase power supply. Rated at 320A at 15% duty cycle and 215A at 35% duty cycle, with 170A at 60% duty cycle, it supports both rutile and basic electrodes from 2mm to 6mm diameter. With thermostatic protection, Class H insulation, and an IP22 protection rating, it is a robust and reliable solution for structural-steel fabrication, general metal fabrication, construction, and welding gates, railings, and frames.

Key Features:

• 70–350A Stepless Current Adjustment — Continuously adjustable welding current for precise control across a wide range of electrode sizes and material thicknesses.
• 320A Maximum Output at 15% Duty Cycle — High peak output for demanding welding tasks, with 215A at 35% and 170A sustained at 60% duty cycle for extended welding sessions.
• Rutile & Basic Electrode Compatibility — Supports both rutile and basic electrodes from 2mm to 6mm diameter for greater welding versatility across structural and general fabrication applications.
• 230V/400V Dual Voltage Input — Operates from 230V single-phase or 400V two-phase power for flexibility across workshop and site power installations.
• 52–73V No-Load Voltage Range — Wide no-load voltage range supports reliable arc ignition with both rutile and basic electrode types.
• Thermostatic Protection — Built-in thermostatic protection prevents overheating and protects the machine during extended welding sessions.
• Class H Insulation — High-grade insulation for safe, durable performance under demanding welding conditions.
• IP22 Protection Rating — Suitable for indoor workshop and sheltered construction site environments.
• Supplied with Welding Kit — Includes a welding kit for immediate operational readiness.
