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. 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. E6013 and E7018 are free; 6010, 6011, 7014, 7024 and the rest are Pro. - FCAW Calculator (Pro) — Complete flux-cored welding parameters with self-shielded and gas-shielded wire data. REFERENCE TOOLS: - Preheat Calculator — Required preheat temperature from material type, thickness, carbon equivalent, and welding process. Essential for structural and code work. - Heat Input Calculator — Heat input from amperage, voltage, and travel speed. Critical for procedures that specify maximum heat input limits. - Amperage Charts — Quick-reference amperage tables by material and thickness. A starter set is free; the complete tables are Pro. - Filler Metal Guide — Match the right filler wire or rod to your base material combination, with AWS classifications. The first material group is free; the rest are Pro. - Gas Flow Guide — Recommended shielding gas types and flow rates for every process and material. - Unit Converter — Convert between metric and imperial welding units. YOUR DATA, YOUR WAY: - Calculation History — Your last 3 calculations are free. Pro keeps every one of them, plus favorites. - 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. - Imperial or Metric — Enter thickness as 3/16" or 0.25 and get results in inches, ipm and cfh. - Light and Dark — Both fully designed, for bright shop environments and outdoor glare. WHAT PRO UNLOCKS: The FCAW calculator, every stick electrode beyond E6013 and E7018, the complete amperage charts, the full filler metal guide, and unlimited calculation history with favorites — plus every calculator and reference tool added in future. Everything else is free, forever: the MIG, TIG and Stick calculators, preheat, heat input, gas flow, the unit converter, and your last 3 calculations. 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. Download WeldCalc Pro and get the right parameters — every time.
