L: Throat depth, namely arms length
Advantage & Feature:
1, Machine body adopts thick steel sheet structure, not easy to deformation
2, Secondary electric conduction parts adopt upper insulation design, effectively prevent short circuit accidents triggered by scrap iron or workpieces, which lays a solid safety foundation for the stable operation of this Resistance Spot Welding Machine. 3, The electrodes moving speed can be adjusted freely, effectively easing collision between electrodes and workpieces and lowering operating noise.
4, Equipped with microcomputer control system, it runs with high precision and stable performance, and supports storing 15 sets of welding parameters to match products of various specifications, fully meeting diversified processing demands of standard Spot Welding Machine.
5, The built-in controller can realize automatic current compensation to guarantee consistent welding effect, and it also supports preheating and tempering treatment for specific materials, optimizing the overall working performance of the whole Resistance Welding Machine. 6, Equipped with water cooling transformer assembled by 15000 gauss permeability silicon steel sheets, it adopts full copper alloy inner core with internal circulating cooling water. This design cuts down impedance and boosts power utilization rate; with 20% duty cycle, it satisfies long-duration welding and high-power output needs. The equipment features longer service life, lower running noise as well as compact and reasonable overall structure.
7, Matched with high-speed solenoid valve, it greatly accelerates welding pace, lifts overall production efficiency and effectively controls production cost.
8, The cylinder is made of high-precision anti-friction duralumin material, featuring rust resistance, low friction coefficient and low operation noise. It achieves faster pressing action and obviously reduces welding spatter.
9, This equipment boasts stable running quality and low failure rate, extending the overall service cycle greatly.
10, It is widely applicable to metal wire processing, electrical appliance production, metal sheet fabrication, microelectronics industry and other relevant fields.
