The MINIFLOOR drive unit transforms the TRIAC into a practical, automatic floor welder. The quick-clamp lock on the holder allows the TRIAC to be assembled and disassembled within a matter of seconds. Its light weight of 6.6 kg (14.55 lbs) makes the MINIFLOOR easy to transport. The drive unit alone weighs 5.3 kg (11.7 lbs). All LEISTER and WELDY speed welding nozzles for flooring will fit. The MINIFLOOR is already worth using for weld seam lengths of 1.20 m (3.9 ft).
