Application

For use between welding generators and hand electrodes and the workpiece . For use in automobile industries, ship building, in transport and conveyor system, tool making machinery, welding robots, etc. Standard

Standard

Adapted to IS:9857, IS:6380, IS:8130.

Technical Data

Voltage Rating : 450V a. c. rms.

Test Voltage : 1000V

Temperature Range : -20°C to +60°C

Minimum Bending Radius : 5 x cable diameter

Cable Construction

Super fine strands of annealed bare copper according to IS:8130, Cl. 6. Elastomeric insulation type SE-1 conforming to the requirements of IS:6380.

Properties

The heavy duty welding cable is resistant to flame, oil, abrasions, tar and grease. Suitable for use in open air, in dry as well as damp interiors.

The high degree of flexibility does not form knots on the cable which could lead to internal break of conductors.
