💡 What technical factors determine the performance of a welding extension cord in high-current welding?

Short answer: it’s about conductor size, insulation, and jacket durability, plus matching plug/receptacle ratings.

- Conductor size and number of conductors (eg 10 AWG, 3-conductor) affect current capacity - Insulation and jacket (STW) protect against moisture and abrasion - Connector compatibility (NEMA 6-50P to 6-50R) ensures a proper, safe connection - Temperature rating and weather resistance enable indoor/outdoor use across -40°C to +90°C
