Features:
1.Adopting medium frequency inverter controller, this MF DC Spot Welder outputs 1000Hz direct welding current for far more stable current performance. 2.Saving energy with lower welding current and electrode pressure;
3.Delivering top quality. Compared with traditional AC welders, it boasts superior welding stability and concordance, featuring fewer craters, finer welding appearance and firmer joints. As a high-performance MFDC Spot Welding Machine, it achieves remarkable upgrades in overall welding effects.
4.Three-phase power supply inputs evenly to lower strike force to the power grid.
5.It requires less power supply and saves 40% electricity than ordinary AC welding machine.
Constitute:
1.Machine body made of thick steel sheet, not easy to deform.
2.Microcomputer control ensures high working accuracy and steady operation.
3.Water cooling transformer: Assembled with silicon sheets of 15000 gauss permeability, it adopts full copper alloy core with internal circulating cooling water. This design reduces impedance, improves power utilization, and supports 20% duty cycle to meet long-time welding demands and high output power. It features longer service life, lower noise and more compact and reasonable structure.
4.Equipped with fast solenoid valve to accelerate welding speed, boost productivity and cut overall production costs.
5.The cylinder is made of high-precision, anti-friction hard duralumin material, which is rust-proof with low friction and noise. It enables faster loading and effectively reduces weld spatter.
6.With stable quality and low failure rate, the equipment enjoys an extended service life.
As a professional Resistance Spot Welding Machine, it is specially suitable for spot welding of aluminum plates. Model
