General Rubber-Sheathed Multi-Core Flexible Cable

A large overseas manufacturing enterprise (customer name: ***) purchased 5,000 welding circuit cables and 2,000 welding machine power cables at once through B2B channels for a new automated welding production line. After delivery, the customer reported that some cables experienced abnormal heating when powered on, and the welding machine output was unstable, seriously affecting production progress. The customer requested urgent remote troubleshooting and possible responsibility for returns or replacements.

We immediately initiated remote technical support services, with senior engineers guiding the customer through the following troubleshooting steps via video conference and online diagnostic systems: 1) Confirming whether the cable specifications match the welder's rated current, and found that the cable cross-sectional area at some of the customer's workstations was smaller than the actual load requirements; 2) Guiding the customer to use a multimeter to measure the resistance at both ends of the cable to rule out internal broken wires or poor contact; 3) Checking the cable reel method and confirming that long-term coiling caused poor heat dissipation; 4) Providing a standardized cable selection table and wiring guidance, and remotely assisting the customer in adjusting 5 overloaded connection points on the production line. All operations were completed step by step through remote collaboration tools, with no on-site dispatch required.
