Designed with advanced IGBT inverter technology and **Power Factor Correction (PFC)**, this machine combines energy efficiency, generator compatibility, and a wide input voltage range, making it suitable for workshop, site, and mobile use. At the heart of the Infinium is a **5” colour LCD touch screen**, providing an intelligent, user-friendly graphical interface for fast setup and precise control. With **Synergic MIG**, parameters are automatically optimised based on material thickness and voltage, while advanced MIG Pulse and Dual Pulse modes deliver superior weld appearance and penetration on a variety of materials. This versatile unit supports **MIG/MAG, TIG AC/DC, and MMA AC/DC** welding processes, including advanced TIG features such as HF or Lift TIG, multi-wave Smart TIG, pulse functions, and full AC control for aluminium welding. MMA welding is equally capable, with pulse mode, hot start, adaptive arc force, and built-in VRD for enhanced safety and arc stability. Weighing only **20 kg**, the Infinium is highly portable without compromising power, offering up to **200A output** and the ability to store **up to 100 user programs** for rapid repeat jobs. A **4-roll wire feed motor** ensures consistent wire delivery, even with longer torches and softer wires. ### **Key Features** - Advanced IGBT multi-process inverter technology - Power Factor Correction (PFC) with wide input voltage **95–265V** - Automatic dual voltage detection (110V / 230V) - Generator friendly design - MIG/MAG: Standard, Synergic, Pulse & Dual Pulse - TIG AC/DC: HF or Lift, Smart TIG, pulse, slope up/down, 2T/4T - MMA AC/DC with pulse, hot start, adaptive arc force & VRD - 5” colour LCD touch screen with intuitive navigation - Smart fan system reduces dust intake and power consumption - Stores up to 100 welding programs - USB port for firmware updates - Advanced error code diagnostics - IP23 protection rating - Fully compliant with **EN 60974-1**, **EU Regulation 2019/1784**, **CE** and **UKCA** ### **Supplied Complete With** - T240-3 MIG Torch – 3 m - T26-4 TIG Torch – 4 m - Gas regulator - Gas hose - Work return lead and clamp - Electrode holder and lead ### **Optional Accessories** - 2-wheel trolley - Wired foot pedal - Wireless foot pedal ### **Technical Data – WS-MU4-1N** - **Input Voltage:** AC 95–265V ±15%, 50/60Hz - **Input Power:** 4.5 / 7.5 kVA - **Current Range:** - MIG: 25–230 A - TIG: 10–200 A - MMA: 10–200 A - **No-Load Voltage:** MIG 80V / MMA 88V / TIG 88V - **Duty Cycle @ 40°C:** 230A @ 25% - **Efficiency:** 85% - **Power Factor:** 0.99 - **Idle Power Consumption:** 30 W - **Wire Spool Capacity:** 5 kg / 200 mm - **Protection / Insulation Class:** IP23 / H - **Dimensions (L × W × H):** 780 × 220 × 430 mm - **Weight:** 20 kg The **Weld Star Infinium 4-in-1** is an all-in-one solution for fabricators, maintenance engineers, and professional welders seeking maximum flexibility, advanced control, and reliable performance in a single compact machine. ## Reviews There are no reviews yet.
