Advantage & Feature:
Machine body adopts thick steel sheet construction, not easy to deformation. As a reliable Resistance Welding Machine, it maintains stable overall performance during long-term operation. Secondary electric conduction parts adopt upper insulation design, effectively preventing short current accidents caused by scrap iron or workpieces.
The electrode moving speed can be adjusted freely to reduce impact on workpieces and operating noise.
Equipped with microcomputer control system, the equipment runs accurately and steadily. This Spot Welding Machine can store 15 sets of welding schedules to adapt to products of various specifications. The controller features automatic current compensation to guarantee consistent welding quality, and supports preheating or tempering for certain materials.
It is fitted with a water cooling transformer assembled from 15000 gauss permeability silicon steel sheets. The internal full copper alloy core with circulating cooling water cuts down impedance and boosts power utilization. With a 20% duty cycle, this Resistance Spot Welding Machine meets the demands of long-hour welding and high power output. It also boasts longer service life, lower noise and a compact, rational structure. High-speed solenoid valve raises welding speed and overall productivity, helping cut operational costs.
The cylinder is made of high-precision, anti-friction hard duralumin material. It is rust-proof with low friction and noise, and delivers rapid loading, which effectively reduces weld spatter.
Stable running quality and low failure rate extend the overall service life of the equipment.
It is widely applicable for metal wire processing, electrical appliance manufacturing, metal plate fabrication, microelectronics and other industries.
