What WeldingCalc is for

Welder settings calculator for hobbyists running MIG/TIG/stick.

Not AWS code-weld. Test bead still wins. Shop paperwork lives on shoppacks.net.

This map lists pages that exist. It is not a keyword dump and it does not treat every article as its own niche. The calculator (or the pack) is the hub. Guides sit under one pillar each.

Thickness → amps

About 1 A per mil on mild steel TIG.

• Thickness & amperage calculator — TIG, MIG, stick, duty cycle.
• Settings card — Printable shop-wall chart.
• TIG amps by thickness — Where the 1-amp-per-mil rule breaks.
• Welder for 1/4 inch steel — 140 A vs a shop machine.

Process choice

Thin metal warps. Pick the process that doesn't.

• MIG or TIG for sheet — 16–20 ga auto-body and duct.
• MIG wire speed — ipm windows by thickness.

Buying a machine

Pick the metal first.

• Beginner welder size — 120 V flux-core vs 140 A MIG vs 200 A TIG.

Runtime & the shop

Duty cycle is thermal. Getting paid is paperwork.

• Duty cycle — It scales with the square of the amp ratio.
• Weld cost — Filler and time.
• Shop Packs — Quotes and follow-ups so the shop actually gets paid.
