1: Direct pressing type
As it is pressed by 2 cylinders directly and left & right electrode bases are installed on one linear guide rail, so its axisality is better than Type of pressing by lever. It is more suitable for smaller diameter workpiece.
2: Type of pressing by lever
Press by lever, pressure is bigger than direct pressing type, it is more suitable for bigger diameter workpiece.
Max welding area is 160 square mm.
1, Adopt the air-powered vertical pressure or air-powered lever pressure system.
2, Adopt the high definition guidance institution.
3, Microcomputer constant pressure control system, twice section discharge, multi- group memory programs.
4, High conduction magnetism silicon sheet steel, secondary whole structure, output current is high.
5, Water cooling transformer, water cooling controlled silicon, and water cooling electrode head.
6, It is used to high quality welding wide range of wire type, plate type, heteromorphosis type copper\aluminum\iron\stainless steel metal etc.
1, Machine body of thick steel sheet.
2, Fast solenoid valve.
3, Cylinder adopt high accurate, anti-friction hard material, which is duralumin.
4, Quality is stable, failure rate is low.
