You're looking at a split-type wire feeder setup that pushes the wire through, not pulls it—makes a difference when you're running longer lines or working in tighter spots where the feeder has to sit separate from the power source.
It handles wire diameters of 0.8, 1.0, and 1.2 millimeters, which covers most common MIG/MAG jobs, and the welding votage range runs from 17 up to 27 volts on the 280 model or 31 on the 315. The current range is 30 to 270 amps for the smaller unit, 50 to 350 for the larger one—so you've got some overlap but teh 315 is clearly for heavier plate. Input capacty is 8 KVA on the 280FK, 14 KVA on the 315F, and you'll need a 380-volt three-phase feed for the 315 model unless you're running the 280 which can take 220V as well (check your shop's supply before ordering).
Load duty cycle sits at 60%, which means you can weld continuously for six minutes out of ten without overheating the inverter—pretty standard for portable gear, but it's not built for production-line marathon sessions where you'd want something with a higher rating. Air cooling keeps it simple, no liquid to leak or maintain.
Power factor is 0.95, so it's pulling current efficiently from line—better than older transformer-based units that waste more as heat. The inverter topology runs at high frequency, which is what keeps the weight down to 13.5 kilograms for the 280FK or 19.8 for the 315F, and the dimnesions are roughly 445 by 245 by 390 millimeters. We usually have stock on both models, but confirm lead time if you need more than 20 units or so.
One thing that catches people: the push-type feeder can struggle with soft aluminun wire over long distances—you'll want a spool gun for that, this machine isn't really suited for it. Anyway, the 315F is the one most buyers go with for structural steel work.
Our standard MOQ is 10 units per model, but we can negotiate for smaller trial orders if you're just getting started.
Lead time is usually 15-25 working days after order confirmation, depending on current production volume and stock availability.
Yes, both models come with CE certification and we can supply ISO documentation upon request—just let us know what you need.
Absolutely, the NBC-280FK is designed to work with AC220V±10% 50Hz, so single-phase is fine—just check your local voltage matches.
They ship fully assembled in sturdy export cartons with foam padding. The split wire feeder is packed separately but easy to hook up.
