WELDING CABLES
Standards :
Generally conforms To Based On CENELEC Hd 22-6-31, VDE 0282, IEC 245-6, BS 6899, IS 6830/84
Conductor :
High conductivity, bare annealed copper flexible conductor EC copper class 5 and 6 generally conforms to IEC 60228, DIN VDE 0281
Insulation :
double Insulated flexible Nitrile Rubber (NBR) insulated
Colour :
Orange / Black jacket
Standard Packing :
coils 100, 200, 300, 500 m
Application :
Designed for the secondary (high current) connection to automatic or hand - held metal arc welding electrodes. it is suitables for flexible use under rugged condiction, on assembly lines and conveyor systems, in machine tool automatically operated line and spot welding machines.
Voltage Drop :
When total cable lenghts in excess of 15 mtrs, are involved it may be necessary to use cables of larger cross section to ensure that the voltage drop is not excessive and welding currents are maintained at adequate levels.
