The Ralli Wolf WFC42 is a lightweight pneumatic weld flux chipper built for fast, precise removal of weld flux and slag after welding operations. A pulley valve design gives operators precise control over the chipping action while keeping operation smooth, avoiding the harsh jerkiness that can make flux removal slower and less controlled on lower-quality chippers.

With a high 4200 blows per minute, the WFC42 clears weld flux quickly, cutting down the time spent on post-weld cleanup between passes — a meaningful efficiency gain in shipyards and fabrication shops running continuous welding operations. Its light 2kg weight and compact 257mm length keep it easy to manoeuvre along weld seams and into tighter working positions without causing operator fatigue over a full shift.

Running on a 1/4" NPT air inlet, it draws 22 cfm — a fairly high consumption for its size, reflecting the high-BPM output needed for fast flux clearing. Built for fabrication shops, shipyards and R&D centres, it's suited to both production welding environments and lower-volume precision work where clean, controlled flux removal matters.
