The CRUXWELD WeldyFi is a portable fillet welding carriage that needs no track. A lever-switched magnet holds it on the steel, brass guide rollers run against the web plate, and four-wheel drive carries your MIG/MAG torch along the fillet at a steady 5–1100 mm/min.

Long fillet welds on stiffeners, beams and panels are where hand welding loses time and consistency: the welder tires, travel speed drifts and the leg size wanders. The WeldyFi takes over the travel. Set it on the plate, drop the magnet lever, let the guide rollers rest against the web and press start.
Its motor runs with encoder feedback through a planetary gearbox, so the speed you set on the knob is the speed it holds along the joint. The torch sits in a quick-attach clamp on an X-Y slide, so the wire lands exactly in the root of the fillet and stays there.
Typical work: stiffeners on deck and side panels, I-beam and H-beam fabrication, girders, frames, tanks and vessels — any carbon or low-alloy steel structure with long, repeated fillet welds.
New to welding automation? These are the flush-fillet settings our technical team starts from with 1.2 mm wire on 6 mm plate. Strike the arc, watch the bead for the first few hundred millimetres and fine-tune travel speed on the knob.
