Series 4

 -Welding machine with medium frequency technology, designed to satisfy a wide range of welding applications, both spot and
projection, allowing to achieve a high quality of the welding points.

- Reduced welding current rise time, time adjustment in ms, symmetrical load on the machine power line.

-Modular concept of the structure, with the possibility of inverting the position of the welding cylinder or of operating with two
opposing welding cylinders.

-Heavy duty chrome plated steel rod cylinder for long life. Adjustable anti-rotation device. All pneumatic components used do not
require lubrication.

- Double adjustable stroke.

- Filter group with sectioning of compressed air connected to the emergency control.

- Liquid-cooled secondary circuit and transformer, hydraulic circuit isolation valve connected to the emergency control. Flow meter
and cooling water temperature measure device.

- Two-stage electric pedal which allows the pieces to be clamped in position by means of the intermediate stage and proceed with
welding only by activating the second stage, after verifying the correct positioning of the pieces.

- Possibility of connecting a second electric pedal to weld using a different welding program.

- Two-hand control with simultaneous control for maximum safety and removable key selector for selecting the control device.

- Welding control and commands for the control of the spot welder installed on a suspended arm for maximum ergonomics of
use of the spot welder.
