The ESAB RC 500 welding resistor is known for its robust construction and reliable operation, even in harsh conditions. It features knife switches for precise adjustment of welding current, allowing for 95 different combinations between 6 and 593 A. With 7 resistor groups, it can handle welding network voltages of 60 V and arc voltages of 35 V. Its low temperature coefficient ensures consistent welding current despite temperature fluctuations. The resistor coils are mounted on ceramic rods for enhanced mechanical stability. You can choose between ZBK or OKC machine and cable connections.
