UNIMIG RazorWeld 350 MIG/TIG/MMA Welder with Separate Wire Feeder - 3-Phase 415V - 350A - RRP $4,000-$5,000 - Complete Professional Setup

UNIMIG RazorWeld Razor 350 (MIG-350) multi-process inverter welder with Razor 350 x4 separate wire feeder, 350A output, 3-phase 415V, Jasic manufactured.


Description


The UNIMIG RazorWeld 350 is a professional multi-process inverter welding system that covers MIG, TIG, and MMA (Stick) welding in a single package. Built by Jasic, one of the world's largest inverter welding manufacturers, this unit delivers 350A in both MIG and MMA modes on 3-phase 415V power. The separate Razor 350 x4 wire feeder with 4-roll gear-driven drive allows remote feeding, giving the operator flexibility to position the feeder at the workpiece while the power source stays at a distance. The power source features digital amperage and voltage displays, crater current control, adjustable inductance (hard to soft), VRD (voltage reduction device) for safety, and 2T/4T trigger modes.


From the photos, the complete system presents in good used condition. The power source and wire feeder are mounted on a purpose-built UNIMIG wheeled trolley. The power source front panel shows dual digital LED displays, multiple rotary controls for amperage, open circuit, crater current, and inductance, plus toggle switches for MIG/MMA selection, VRD, and 2T/4T modes. The wire feeder panel has rotary controls for wire feed speed (1.5-24 m/min) and voltage (15-38V), plus a standard/push-pull selector and wire inch button. The data plate confirms model MIG-350, 3-phase 415V input, 350A at 40% duty cycle, 221A at 100% duty cycle, IP21S protection, F-class insulation, and RCM compliance. Included accessories visible are a MIG torch (SB36 type), earth clamp with lead, 3-phase power cable with orange industrial plug, gas regulator with flowmeter, and a loaded wire spool.


New UNIMIG Razor 350 SWF systems retail for approximately $4,000 to $5,000. At auction, this complete professional setup represents an exceptional opportunity for any fabrication workshop looking to add or upgrade their multi-process welding capability.
