UNIMIG Workshop Series 390S MIG Welder with KT 50 Remote Wire Feeder - 3-Phase - 375A Output, 300A at 100% Duty - European Made (Hungary)
UNIMIG Workshop Series 390S MIG/MAG welder with KT 50/390 remote wire feeder, 40-375A output, 3-phase 410V, 300A at 100% duty cycle, WGA manufactured (Hungary).
Description
The UNIMIG Workshop Series 390S is a heavy-duty industrial MIG welder built by WGA in Hungary and designed for continuous professional fabrication. This is not a hobby unit. With 375A output, 355A at 70% duty cycle, and a genuinely impressive 300A at 100% duty, this welder is built to run all day without rest in a production workshop environment. The separate KT 50/390 remote wire feeder allows the operator to position the wire drive at the workpiece, minimising wire feed issues on long lead runs and providing flexibility for large fabrication jobs.
From the photos, the 390S power source is a substantial floor-standing unit on an integrated wheeled trolley with gas bottle holder. The front panel features a stepped voltage selector, fine voltage trim adjustment, inductance/mode selector, and indicator lights. Output connections include heavy-duty dinse terminals and multi-pin remote feeder connectors. The KT 50 wire feeder features a 10-position programme selector, variable wire speed control, and burn-back/run-in adjustment knobs, with a Euro torch connector. Both data plates are legible: the 390S confirms 40-375A output, 3x410V 50Hz input, 25A fuse, 300A at 100% duty, F-class insulation, IP21 rating, and EN 60974-1 compliance. The KT 50 plate confirms 400A max welding current at 100% duty, 0.6-1.4mm wire range, and IP21 protection. A blue shielding gas cylinder with dual-gauge regulator is present. MIG torch, earth clamp with lead, and interconnect cable bundle are all included.
New workshop MIG welders in this output class retail for $3,000 to $5,000. This is genuine industrial welding capacity at auction prices, with European build quality.
