Velo — speed stabilization system for manual MIG/MAG welding

Technical specifications

Specifications are taken from the manufacturer’s technical documentation. Updated 11/06/2026. Customs codes are for reference only; the final code is determined at customs declaration for the specific model.

Description

On a long weld it is hard for the welder to hold the torch steady relative to the workpiece and move it evenly, which results in an uneven weld. With Velo, heat input stays even along the whole length and weld quality stays stable. The set includes the WF 25i Velo wire feeder, a torch holder adjustable by turning without tools, the additional Velo wire feeding system, a manual MIG/MAG feeder and an OPT/i Velo licence. An existing system is upgraded in two steps: the software is activated and the WF 25i Velo is fitted with a torch adapter. The assistant works with all main processes, Standard, LSC, Pulse, PMC and CMT, on steel and chromium-nickel steels. With SyNext synergy it is enough to set the leg size (a-dimension), weld profile and spatial position, and the system selects the remaining parameters itself. The penetration and arc length stabilizers in LSC and PMC and the low heat input of CMT are retained with Velo, which matters for thin sheet and welds in different positions.

How to choose

Velo makes sense where there are many long fillet and butt welds and robotization is not practical. Depending on the task, a welder with this assistant is comparable in productivity to a welding robot; it makes long welds easier for an experienced welder and helps a less experienced one get a quality result quickly. If the workshop has no TPS/i or iWave Multiprocess, the assistant is bought together with a power source, because the Fortis series is not listed as compatible.
