WeldConnect, the new welding app from Fronius, provides you with a whole host of options for functional use and wireless interaction with the current generation of Fronius systems in many different languages. Intelligent wizards for MIG/MAG and TIG guide you quickly and easily to the right output parameters for your welding solution. In combination with the JobManager, you can conveniently create, manage, and transfer welding set values in no time using a mobile device. With the keyless function, welding systems can be unlocked and locked without a key (i.e. without an NFC card). You can view information about welding systems connected to the app with ease. In combination with WeldCube Premium, this enables tracing actual data that has been documented at component level—even when welding manually. WeldConnect—a recap of your benefits at a glance: / Always keep your welding solutions close to hand, on all your mobile devices / Find a solution quickly and easily with the wizard / Wireless interaction with the welding system—also via Bluetooth / Straightforward capture of component information for welding data documentation / Save, send, and edit jobs / Unlock welding systems without a key (i.e. without an NFC card) / Easy configuration of the WeldCube Connector All WeldConnect features in detail. / How does the wizard work? The Wizard supports the selection of the correct welding parameters. This set of welding parameters can be transmitted wirelessly to the welding device. This saves time when setting all welding parameters. The Wizard is available for MIG/MAG and TIG. The parameters can be saved online and retrieved at any time. / What does the JobManager do? Save and edit all jobs (sets of target parameter sets) of the connected welding device directly in the app. The saved jobs can thus be transferred wirelessly to another welding device. / Device Information The Device Information area provides a comprehensive overview of all of the main configuration data, components, and available function packages. From there, you can also access the SmartManager (system website) for the connected welding system quickly and easily. The keyless function allows authorized users to log in to and out of the system without an NFC card. / Component-related documentation Consistent component documentation through simple and fast recording (manual input or scan function) of component information: Component part number, component serial number and seam number. With this feature you can guarantee that the welding data recorded is consistently assigned to the same component. Combined with WeldCube Premium, this provides a wide range of options in terms of visualization, statistics, and analysis. / WeldCube Connector With WeldConnect, the WeldCube Connector can be configured quickly and easily.

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.

Verdict
The clearest difference is in-app purchases: WeldConnect at none against WeldCalc Pro's 3. WeldConnect also leads on device support (3 vs 1) and iOS requirement (15.4 vs 17.0). WeldCalc Pro's advantage is update cadence (every 3 weeks vs every 2 months). On price and ads there is nothing between them.
