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. The machine is equipped with precise equipment for weft cutting (won nation patent ZL02208722.2) and positioning (won nation patent ZL0-2208721.4), so the length of weft is identical and regular, it is unnecessary to slice the side. Drawing mesh system adopts elastic tension link that met nation patent ZL200520024380.9 and opening positioning mesh, it is easy to regulate mesh hole, and mesh opening size is rather accurate, welding aperture could 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).
