Feature

 

welding cable

 

HOFR NBR rubber extra flexible pure copper welding cable is a high-performance welding cable designed for high-current connections. The cable uses high-conductivity bare soft copper conductors (category 5 and 6 conductors in accordance with IEC 60228 and DIN VDE 0281 standards) to ensure excellent electrical performance and excellent flexibility. The insulation layer is made of oil-resistant and wear-resistant NBR nitrile rubber material, which has excellent heat resistance, oil resistance, and mechanical wear resistance. The rated voltage is 600V, the test voltage is up to 2500V, and it can work stably in a wide temperature range of -30℃ to +90℃.

 

Certification

 

 

UL certification is a safety standard widely recognized in the North American market. It complies with UL and other relevant specifications, allowing welding cables to smoothly enter the US, Canadian and other international markets, and enhance the global competitiveness of products. UL certification not only means that product quality meets international standards, but also enhances customer confidence, enhances the market influence of the brand, and enables enterprises to stand out in industry competition

FAQ

 

Q: What type of cable is used for welding?

A: It is a flexible, durable, and highly conductive cable designed to carry the high currents required for welding applications. It is typically a stranded copper conductor that is extremely flexible, and a rubber or synthetic rubber (such as EPDM) insulation that is tough, abrasion-resistant, and resistant to heat, oil, and moisture.

Q: How many AMPs is a #2 welding cable good for?

A: A #2 welding cable is typically rated for about 115 to 150 amps of continuous current, depending on the insulation type, ambient temperature, and whether the cable is used in open air or in conduit.
