steel grating medium frequency welding machine, steel grating welding equipment, steel frame lattice welding machine, steel frame lattice welding equipment

Features:

The machine is to finish flat-rolled steel and wrenched steel welding automatic production line.

1,High productivity, saving energy. Welding speed is able up to 15-25 line rods per minute, reasonable design of welding loop.

2,easy to operate and display clearly. By means of terminal man-machine interaction can achieve functions following: real-time monitor machine’s performance; set line rod pitch and number; record numbers of work-piece.

3,Transformer is made by superimposing silicon steel sheets which are high quality and imported. Transformer has internal water cooling, casting by epoxy resin and has the function for warning of over-temperature.

4,welding process is controlled by micro-computer, ensuring constant current even if voltage undulate and welding duty vary.

5,There are 2 kinds controlling functions of constant current and constant voltage, controller can memorize up to 15 programs.

6,Be able to use 3 pulses to control, the second can be set 1-9 times, special suitable for thicker material.

7, There is function for fault self-monitor, displaying on the LED screen.

8, Very strong protecting functions: non-water and insufficient water pressure, transformer over-heat SCR over-heat, over-big current and over-load.

Applications: the platform of such trades as petroleum, chemical industry, electron, quay, municipal administration, environmental protection, national defence etc.
