FAQ

‌Q. How does cable diameter affect welding performance?‌
Answer: Larger diameters (e.g., 50mm²) reduce resistance for high-current applications (≥300A), while thinner cables (2mm²-6mm²) are ideal for precision tasks.

‌Q. Is welding cable flexible enough for robotic welding?‌
Answer: Yes, our 16mm²-25mm² cables feature multi-stranded copper conductors with 30% higher flexibility than standard cables, designed for robotic arms.

‌Q. Can welding cables be used outdoors?‌
Answer: Absolutely. Our NBR/PVC insulation withstands UV exposure (-30°C to +90°C), making them ideal for shipbuilding and construction sites.

‌Q. How to calculate the right cable length for a welding project?‌
Answer: Use the formula: Required Length = (Machine Power × Duty Cycle) / (Current² × Resistance). Our engineers provide free calculations.

‌Q. What’s the difference between welding cable and battery cable?‌
Answer: Welding cables handle intermittent high pulses, while battery cables (e.g., 50mm² for EVs) require sustained current flow with lower resistance.

‌Q. How often should welding cables be replaced?‌
Answer: Inspect every 6 months. Replace if insulation cracks or resistance increases by 15%. Our cables average 5-8 years lifespan.

‌Q. Do you offer custom-colored welding cables?‌
Answer: Yes. Orange/black coding for polarity, or color-matched to your branding for large-volume orders (MOQ 500 meters).

‌Q. Why choose direct manufacturer sourcing?‌
Answer: We eliminate middlemen costs, offering 12-18% savings, 10-day lead times, and free technical support for bulk orders.
