Note: Total cable length = Distance × 2 (welding cable + ground cable)

CALCULATION RESULTS

⚠ WELDING APPLICATION NOTE: Welding equipment requires stable voltage for optimal performance. This calculator uses a maximum 2%-3% voltage drop limit for welding applications to ensure consistent arc stability and weld quality. Standard extension cords use 3% limits, but welding demands tighter tolerances.
⚠ SAFETY NOTICE: This calculator is optimized for welding and heavy-duty applications with voltage drop limited to 2%-3% for maximum performance and safety. Always use SO/SOOW (hard service) cord rated for the amperage. Verify with local electrical codes and consult a licensed electrician before installation. Never use standard household extension cords for welding equipment.
