WIRES & CABLES
WELDING CABLE
Application
Welding cables are designed for use in Electric Arc- Welding Machine to power an Electrode, its design is able to withstand tearing, abrasion, impact and chunking extending the life of the cable in harsh applications.
Conductor
Fine wire (class 5) strands of 99.9% Copper Conductivity, least resistance and multi drawn for uniformity in dimensions and flexibility.
Insulation
Specially formulated grade of PVC nitrile blend used for insulation.
Benefits
1. Flame Retardant
2. Oil Resistant
3.Compression Cut Resistant
4.Survives Rough Handling
2. Oil Resistant
3.Compression Cut Resistant
4.Survives Rough Handling
Marking
The cables are marked as "Masai Cables" and KS 1637
