Quick Reference

General Guidelines

  • Thinner materials = lower WFS, shorter arc length
  • 0.030" wire is versatile for 14ga to 1/4" steel
  • Increase WFS 10-15% for vertical up welding
  • Push angle 5-15° for better wetting

Material Notes

  • Aluminum: Use 0.035" or 0.045" with 4043/5356 wire
  • Stainless: Lower voltage, tighter arc, push technique
  • Flux-cored: Can use 100% CO₂ or 75% Ar/25% CO₂
