Sheath Color: Orange ( Tinned conductors ) Black ( Plain conductors )

Flexible aluminium conductors available upon request.

APPLICATION :
This range of Cables are designed as highly flexible voltage leads, primarily for the secondary (high current) connection to automatic or hand held metal arc welding electrodes .
May also be used for non welding applications such as earthing return leads, flexible tails on power supply. Busbar connections.

TECHNICAL DATA
:
Voltage: 100V (If used in an environment where they are not liable to sustain mechanical damage these Cables may be used at 450/700V in the control panels, switchgears etc.
Temperature Rating: -20 to +85°C
Bending Radius:
6 x Overall Diameter

RATING FACTORS :

The current ratings given are based on an ambient temperature of 25 Deg. Rating factors for higher temperatures are: Ambient Temp: 30 Deg 35 Deg 40 Deg 45 Deg Rating Factor: 0.96 0.91 0.87 0.82 Where total cable lengths in excess of 15m are involved, it may be necessary to use cable of larger cross section to ensure that the voltage drop is not excessive and welding currents are maintained at adequate levels.

DUTY CYCLE :

The duty cycle is defined as the time for which the current flows expressed as a percentage of the complete cycle, which is taken as 5 minutes. Since the length of time for which current flows during a welding operation varies, occasional to continuous, the duty cycle can vary from as little as 20% to a maximum of 100% on automatic operation.

Automatic Welding up to 100%.
Semi Automatic Welding 30-85%.
Manual Welding 30-60%.
Intermittent or Occasional Welding up to 20%.
