This
Resistance Spot Welding Machine integrates mature structural design and intelligent control, and boasts outstanding advantages and features as follows:
Machine body adopts thick steel sheet construction, not easy to deformation.
Secondary electric conduction parts apply upper insulation structure, effectively preventing short current accidents triggered by scrap iron or workpieces.
Electrode moving speed is steplessly adjustable, which reduces impact on workpieces and operating noise.
Equipped with microcomputer control system, the equipment delivers high precision and stable performance. It can store 15 sets of welding schedules to adapt to products of various specifications, a core merit of this professional
Spot Welding Machine.
The controller realizes automatic current compensation to maintain consistent welding quality, and supports preheating or tempering treatment for certain materials.
It is fitted with a water cooling transformer assembled from silicon sheets with 15000 gauss permeability. Adopting full copper alloy core and internal water cooling structure, the transformer cuts down impedance and improves power utilization. With a 20% duty cycle, it fully meets the demands of long-duration welding and high power output. This design extends service life, lowers noise and creates a more compact and rational layout for the
Resistance Welding Machine.
High-speed solenoid valve accelerates welding cycles to lift productivity and cut production costs.
The cylinder is made of high-precision, anti-friction duralumin material, featuring rust resistance, low friction and low noise. It enables quicker load movement and effectively reduces weld spatter.
Reliable performance brings stable running quality and low failure rate, greatly prolonging the overall service life of the equipment.
Widely applicable to metal wire processing, electrical appliance manufacturing, metal plate fabrication, microelectronics and other industries.
