The shelf is made of thick steel board and this kind of machine adopts closed straightened wire ,upright gearbox and electromagnetism stepless adjustable speed ,integrated clutch sends the weft so the hole of mesh is very even and firm, welding is controlled by three-phase power electronics. This machine will stop working by digital control when the length is enough welding power is high and the structure is compact, adjustable control is also very meticulous.
