WeldMaster: Welding Calculator

New: Lifetime unlock. Pay once and keep every Pro feature forever. No subscription, no renewals.

WeldMaster is the welding settings calculator built for working welders, fabricators, and students.

Pick your process, material, and thickness — get starting amperage, voltage, wire feed speed, gas flow, and polarity as honest ranges you tune to your machine. Brand-agnostic and 100% offline: it works in the shop, in the field, and inside metal buildings with zero signal.

FREE • MIG (GMAW) calculator — mild steel, real shielding gas options (C25, C100, 90/10 and more), short-circuit vs spray transfer guidance • Gauge chart — exact sheet steel gauge to inches and millimeters • Troubleshooting starters — porosity, spatter, burn-through

PRO — ONE-TIME PURCHASE, NO SUBSCRIPTION • MIG stainless & aluminum with gas compatibility warnings • Flux-core: self-shielded E71T-11 AND dual-shield E71T-1 — with the polarity and gas each one actually needs • Stick (SMAW): 6010, 6011, 6013, 7014, 7018, 7024 — published amperage tables by rod diameter, polarity per rod • TIG (GTAW): amperage, tungsten type & size, cup, filler rod, AC balance & frequency for aluminum • Heat input calculator with a built-in travel speed timer • Preheat & carbon equivalent (CE) guidance • Electrode chart & filler metal selector (including dissimilar 309L and 4043 vs 5356) • Troubleshooting guide: 14 weld defects with cause-ranked fixes and bead diagrams • My Setups: save the settings that actually worked on YOUR machine — name, machine, process, notes

Every result is a starting point clearly labeled as such. WeldMaster is a reference aid — always follow your WPS and applicable code requirements.

Made for MIG welders, TIG welders, stick welders, pipefitters, boilermakers, ironworkers, farm and hobby welders, and welding students.
