MIG Welding Settings Calculator (by Thickness)
Starting amperage and wire feed speed for short-circuit MIG on mild steel from material thickness.
These are STARTING numbers for short-circuit transfer on clean mild steel — set them, run a bead, then tune voltage by ear to the bacon-sizzle. Over ~6 mm you need multiple passes, preheat thinking, or spray transfer with higher voltage and 100% argon-rich gas.
Formula
MIG Welding Settings Calculator (by Thickness) is a free mig welding settings for welding engineers, fabricators and CWI inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About MIG Welding Settings Calculator (by Thickness)
Starting amperage and wire feed speed for short-circuit MIG on mild steel from material thickness. The calculation implements A ≈ 1 amp per 0.001″ thickness; WFS = A × burn rate (0.030″: 2 ipm/A · 0.035″: 1.6 ipm/A) (Miller / Lincoln Electric MIG setting guides). These are STARTING numbers for short-circuit transfer on clean mild steel — set them, run a bead, then tune voltage by ear to the bacon-sizzle. Over ~6 mm you need multiple passes, preheat thinking, or spray transfer with higher voltage and 100% argon-rich gas.
How to use MIG Welding Settings Calculator (by Thickness)

Frequently asked questions
What formula does the MIG Welding Settings Calculator (by Thickness) use?+
It computes A ≈ 1 amp per 0.001″ thickness; WFS = A × burn rate (0.030″: 2 ipm/A · 0.035″: 1.6 ipm/A), per Miller / Lincoln Electric MIG setting guides. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
These are STARTING numbers for short-circuit transfer on clean mild steel — set them, run a bead, then tune voltage by ear to the bacon-sizzle. Over ~6 mm you need multiple passes, preheat thinking, or spray transfer with higher voltage and 100% argon-rich gas.
Does this follow AWS/IS welding codes?+
Each tool implements the formula from the cited code or handbook (AWS D1.1, IS 800, ISO/EN). Qualified WPS values always govern over any calculator for code work.
Is the MIG Welding Settings Calculator (by Thickness) free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
