What is Inductance in MIG Welding? – Effects, Settings & Tuning

Intro Inductance is one of the most misunderstood controls on a MIG welder, yet it directly shapes your weld bead and arc stability. Many new makers skip adjusting it and wonder why their welds spatter excessively or burn through metal. In this guide, we break down what MIG inductance is, how it impacts your welding, and how to tweak it for cleaner results.

Body

• What inductance means for MIG welding: It controls the rate of current rise when the wire touches the workpiece. Higher inductance slows current surge; lower inductance speeds it up.
• Key effects:
  • Low inductance: Fast arc response, crisp arc, more spatter, good for thin metal.
  • High inductance: Softer arc, less spatter, wider bead, ideal for thicker steel.
• Step-by-step setting & adjustment tips
• Common mistakes to avoid
• Quick reference table for different materials

Closing Inductance tuning turns a rough weld into a smooth one. Small adjustments go a long way, whether you’re working on your first project or refining a complex build.
