Features:
High working efficiency: This Spot Welding Machine is capable of producing 1000 pieces per day.
Ultra-low loose welding rate: Only 5 defective loose welding pieces occur among 1000 finished products.
Ensures finished workpieces free from deformation and discoloration.
Outstanding energy-saving performance: It saves 40% more energy than ordinary conventional equipment.
Cost-effective electrode replacement: Worn electrodes can be replaced conveniently; there is no need to change the whole electrode and electrode base, only the electrode accessories need replacement, which effectively cuts down production costs.
Uniform three-phase power input brings no adverse impact on the power grid.
Fitted with PLC touch screen and clear LED display, supporting simple parameter adjustment and easy operation. Designed as Automatic Type, it is equipped with guide rails and adopts precise PLC control system to realize full-process automatic welding.
The whole machine is fabricated with thick steel plates, featuring solid structure and strong anti-deformation capacity.
Adopts microcomputer control system to guarantee stable operation and high machining precision.
Built-in water-cooled transformer: Assembled with 15000 gauss permeability silicon steel sheets internally, filled with circulating cooling water and configured with full copper alloy core. It effectively lowers impedance and boosts power utilization rate. The 20% duty cycle fully meets the demands of long-duration welding and high power output. This configuration extends service life, lowers operating noise and optimizes internal structure to be more compact and reasonable.
Matched with high-speed solenoid valve greatly accelerates welding progress, further lifting overall productivity and reducing comprehensive production costs.
The cylinder is made of high-precision wear-resistant hard duralumin material, which is rust-proof with low friction and low running noise. It realizes faster feeding speed and effectively reduces welding spatter.
Stable operating performance with low failure rate, greatly prolonging the service life of the Automatic Welding Machine.
Application: Ideal welding equipment for processing condensers and evaporators.
