Faction characteristics This machine adopts electrical synchronous control technique, both welding time and cent-control welding is composed of digital and integrated electric circuit. This operation is accurate, it has stable function, firm welded point, and without welded tracks. Not only welding speed is fast, but also it is easy to learn and operate. Step motor controls fallen weft structure and drawing materials are automatic (this technology has won nation patent ZL200520024381.3), so it is even and accurate, the edge of mesh is regular, it is unnecessary to slice the ends. Drawing mesh adopts the device with elastic tension link that met nation patent ZL200520024380.9 and fixing mesh, it is easy to regulate mesh hole, and mesh size is rather accurate, welding aperture could also adjust randomly within range. Use of the product 1) Enclosure mesh and building roof mesh 2) Building (reinforcing construction mesh, floor warming mesh, seed-bed mesh and flower room mesh).
