MIG, TIG, Stick & FCAW welding calculators with amperage charts, heat input, preheat, tungsten & electrode database. 100% offline. Built for the shop floor. WeldCalc Pro turns your iPhone into a complete welding calculator for every welder, fabricator, and engineer on the shop floor — brand-neutral, 100% offline, no Wi-Fi required. Get accurate parameters for MIG/GMAW, TIG/GTAW, Stick/SMAW, and Flux-Cored/FCAW welding — all in one app, 100% offline, with no brand lock-in. Stop guessing your settings. Whether you're running a MIG welder on mild steel, TIG welding stainless, striking a 7018 rod, or dialing in flux-cored wire, WeldCalc Pro delivers the right amperage, voltage, wire feed speed, gas flow rate, and travel speed for your joint. WELDING CALCULATORS: - MIG/GMAW Calculator — Voltage, wire feed speed, gas flow, and amperage for solid wire welding. Covers carbon steel, stainless steel, and aluminum across all common wire diameters. - TIG/GTAW Calculator — Amperage, gas flow, tungsten size, and filler rod selection. Supports steel, stainless, aluminum, chromoly, and more. - Stick/SMAW Calculator — Electrode selection, amperage ranges, polarity, and technique guidance for every common rod type including 6010, 6011, 6013, 7014, 7018, and 7024. - FCAW Calculator (Premium) — Complete flux-cored welding parameters with self-shielded and gas-shielded wire data. - Preheat Calculator (Premium) — Calculate required preheat temperatures based on material type, thickness, carbon equivalent, and welding process. Essential for structural and code work. - Heat Input Calculator — Compute heat input using amperage, voltage, and travel speed. Critical for procedures that specify maximum heat input limits. - Carbon Equivalent Calculator — Determine weldability of steel alloys using CE and Pcm formulas. REFERENCE GUIDES: - Filler Metal Guide (Premium) — Match the right filler wire or rod to your base material combination. AWS classifications included. - Electrode Database — Comprehensive data on 10+ electrode types with amperage ranges, positions, polarity, coatings, and AWS classifications. - Amperage Charts — Quick-reference amperage tables organized by material and thickness. - Gas Flow Guide — Recommended shielding gas types and flow rates for every process and material. - AWS Classification Reference — Decode electrode and wire designations at a glance. YOUR DATA, YOUR WAY: - Calculation History — Every calculation is saved automatically. Review, compare, and learn from past results. - Favorites — Star your most-used calculations for instant access. - 100% Offline — No internet required. Every calculation runs on-device. Use it in the shop, on the pipe, or in the field with zero connectivity. - Dark Mode — Full dark mode support designed for bright shop environments and outdoor glare. FREE vs PREMIUM: Free includes MIG, TIG, and Stick calculators, heat input calculator, carbon equivalent calculator, electrode database, amperage charts, gas flow guide, AWS reference, history, and favorites. Premium unlocks FCAW calculator, preheat calculator, filler metal guide, premium materials, and all future calculators and reference tools as they are added. Built for welders, by welders. WeldCalc Pro uses industry-standard formulas and AWS reference data — not locked to any single brand or machine. From apprentice to CWI, this is the welding reference app that belongs in your pocket.
