Welding calculators
Free, no sign-up, nothing to install
Starting points for machine settings, built from published manufacturer data with the sources listed on every page. They give you a range and a reason, not a single number — because the number that's right for your rod, your machine and your plate isn't knowable from a web page.
7018 amperage →
Amps for stick by rod diameter, position and plate thickness. Shows the published range and where in it to start.
MIG settings →
Wire size, amperage, voltage window and wire feed speed for mild steel, from a thickness and a joint type.
Wire speed ↔ amps →
Your machine has a wire speed dial; the chart is in amps. Convert either way, for any wire diameter.
Why these are different from the other charts
Most welding settings charts online are the same table copied between sites, with no source and no indication of how much the numbers move between brands. That's not a small detail: ESAB publishes 90–160 A for a 1/8 in 7018, while the figure repeated everywhere else starts at 110 A for the same size rod. Both are honest — they describe different electrodes — and a chart that hides the spread is telling you it knows more than it does.
So these show the range, cite where it came from, and say plainly when your own rod box or machine door beats them.
Settings are the input. The bead is the evidence. Bead Score photographs a finished bead and scores it against D1.1-style visual criteria, logs the settings that produced it, and tells you the one thing to change on the next pass. Practice feedback — not an inspection, and not a substitute for a Certified Welding Inspector.
