Advantage & Feature
As a professional
Resistance Spot Welding Machine, this equipment delivers reliable performance for diverse joining tasks.
Machine body of thick steel sheet, not easy to deformation.
Secondary electric conduction parts adopt upper insulation design, to avoid short current accident caused by scrap iron or workpiece.
The electrodes speed can be adjusted freely, to reduce impact on workpieces and operating noise.
Equipped with microcomputer control system for high precision and stable operation. This Spot Welding Machine can store 15 sets of welding schedules to match products of different specifications.
The controller can automatically compensate current to maintain consistent welding quality, and support preheating or tempering treatment for certain materials.
It is fitted with water cooling transformer assembled with 15000 gauss permeability silicon steel sheets. Adopting full copper alloy inner core and internal water cooling structure, this
Resistance Welding Machine features lower impedance and higher power utilization. With 20% duty cycle, it meets demands for long-duration welding and high power output, while boasting longer service life, lower noise and a more compact and rational structure.
Equipped with high-speed solenoid valve to accelerate welding procedures, raise productivity and cut production costs.
The cylinder is made of high-precision, wear-resistant hard duralumin material, which is rust-proof with low friction and noise. It realizes faster loading and effectively reduces weld spatter.
Stable overall quality with low failure rate, extending the service life of the whole equipment.
It is widely applicable for metal wire processing, electrical appliances manufacturing, metal plate fabrication, microelectronics and other industries.
