Suspension-type welder К355АМ of МСО-4501У1 type is designed for contact flash welding by pulsating flashing of rails with cross-section ranging from 6400 to 10000 mm2 and for field flash trimming right after welding.

The welder can be powered from AC mains, diesel-generator plant and motor-generator set.

 

The complete set of delivery includes:

1. Welder

2. Control Cabinet

2.1. Power system

3. Pump station

4. * Water cooling plant

5. Electric connectors

6. Hydraulic connectors
