Flexible Welding Cable

Ambient temperatures: cable operating temperature also varies according to the prevailing ambient temperature.  EPR / CSP cables are designed to give optimum performance up to an operating temperature of 85oC at an ambient temperature of 25oC.
 Operations under severe conditions: High operating temperatures or prolonged maximum loading of the cable reduce the service life or makes the cable too hot to handle.  Thus under conditions where a long service life cannot be expected or where a high surface temperature is tolerable, the current rating for 25^oC may be applied up to an ambient temperature of 40

Very intermittent or occasional welding : Up to 20%

Manual welding : 30 - 60%

Semi-automatic welding : 30 - 85%

Automatic welding : up to 100% .

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 welding operation varies from occasionally to continuous, the duty cycle can vary from as little as 20% to a maximum of 100% on automatic operation.  As conductor temperature varies according to time in use as well as current, the following ratings are given as a guide

For current ratings see below.

Minimum bending radius: 6 x overall diameter

Operating temperature: maximum 85^oC, Minimum flexing -20^oC

Color: orange, yellow or black
